Letter from the Editor<br />

While the goal <strong>of</strong> the <strong>Journal</strong> <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> is to present to you a publication <strong>of</strong> the highest standard with<br />

the best academic work in our industry, it is also our goal to push a few buttons so that readers and contributors alike may<br />

reflect on the direction <strong>of</strong> our industry and provide fuel for thought for our further development.<br />

In this issue you will find six eloquently written papers with opinions backed and derived from testing. Some<br />

readers may have read a few <strong>of</strong> these papers before as several are award winners. But as your editor, let me ask you to revisit<br />

all these papers because they shed a light on our industry in a way that is meaningful as a collected body <strong>of</strong> work. One<br />

question we need to ask ourselves is, Where do we want technical analysis to be in five, ten, or perhaps twenty years from<br />

now? Another question I challenge our entire industry to reflect upon is this; What responsibility does a technical analyst<br />

have to minimize risk to principle and minimize capital drawdown? Are these responsibilities entirely in the hands <strong>of</strong> the<br />

trader? As an example you will find Parker Evans, in An Empirical Study <strong>of</strong> Rotational Trading Using the %b Oscillator,<br />

<strong>of</strong>fers in his own conclusion, “Admittedly, we have presented back test results that fly in the face <strong>of</strong> the well-worn trader’s<br />

axiom, Cut your losses short; let your pr<strong>of</strong>its run. Table 2 confirms that the %b BW system <strong>of</strong>fers no protection against<br />

ruinous losses at the asset level.” In the paper named Ichimoku Kinko Hyo, by Véronique Lashinski, Table I: <strong>of</strong>fers total<br />

results showing the percentage <strong>of</strong> winners is less than 40%. In Buff Dormeier’s paper, Price and Volume, Digging Deeper, early versions had a bullish bias to<br />

the paper that was identified by the Judges for the Charles Dow Award. When a larger look back period within the charts was requested, it was discovered the<br />

equity curve in Chart 7 experienced a sharp drawdown in 1998, though the summarized results would not be significantly impacted.<br />

If any logic being examined experiences a 40 - 50% drawdown at any point, yet still ends with a strong finish that yields a statically backed positive<br />

conclusion, is this something we can view as reality and genuine growth to our Body <strong>of</strong> Knowledge about our tools and methods? Would a pr<strong>of</strong>essional analyst<br />

still be employed the full duration <strong>of</strong> a test interval if a sharp equity curve “blip” occurs? We each have different views about acceptable risk exposure. While<br />

this is not an easy answer, the question must be considered.<br />

Statistics is essential to prove the validity <strong>of</strong> our methods, but are our methods being tested to mirror how they are used by the most skilled technicians?<br />

If only small integral parts <strong>of</strong> a skilled technicians’ logic tree is tested, does it help or hurt our industry and the method being examined? I do not know how<br />

to bring the best technicians and most accomplished academic statisticians together, but I am confident our industry as a whole would benefit if we could find<br />

a solution to this pickle we find ourselves currently. These papers deserve the highest recognition, but it is my hope they prompt you to give the goals <strong>of</strong> our<br />

industry and how best to move our craft forward much deeper thought.<br />

The final article is a reprint excerpt from the book Benner’s Prophecies <strong>of</strong> Future Ups and Downs in Prices written by Samuel Benner in 1884. Benner<br />

touches upon Fibonacci cycles and considers cycles <strong>of</strong> prosperity and contraction in several markets. We will begin to include a reprint in each <strong>Journal</strong> issue<br />

from hard to find works that mark historical milestones in our industry. Benner’s Prophecies is a most appropriate selection to begin this new addition to the<br />

<strong>Journal</strong> because the book is recognized as the first financial book written in North America with technical forecasts. Considering current global equity market<br />

trends you will find this work written over a century ago on market panics a most intriguing read.<br />

The Boundaries <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong><br />

Milton W. Berg, CFA<br />

<strong>Market</strong> Prognostication<br />

1<br />

In his treatise on stock market patterns, the late Pr<strong>of</strong>essor Harry V. Roberts 1 observed that “<strong>of</strong> all economic time series, the history <strong>of</strong> stock prices, both individual<br />

and aggregate, has probably been most widely and intensively studied,” and “patterns <strong>of</strong> technical analysis may be little if nothing more than a statistical artifact.” 2<br />

Ibbotson and Sinquefield maintain that historical stock price data cannot be used to predict daily, weekly or monthly percent changes in the market averages.<br />

However, they do claim the ability to predict in advance the probability that the market will move between +X% and -Y% over a specific period. 3 Only to this very<br />

limited extent – forecasting the probabilities <strong>of</strong> return – can historical stock price movements be considered indicative <strong>of</strong> future price movements.<br />

In Chart 1, we present a histogram <strong>of</strong> the five-day rate <strong>of</strong> change (ROC) in the S&P 500 since 1928. The five-day ROC <strong>of</strong> stock prices has ranged from -27% to<br />

+ 24%. This normal distribution 4 is strong evidence that five-day changes in stock prices are effectively random. Out <strong>of</strong> 21,165 observations <strong>of</strong> five-day ROCs, there<br />

have been 138 declines exceeding -8%, (0.65% <strong>of</strong> total) and 150 gains greater than +8% (0.71% <strong>of</strong> total). Accordingly, Ibbotson and Sinquefield would maintain that<br />

over any given 5-day period, the probability <strong>of</strong> the S&P 500 gaining or losing 8% or more is 1.36%. Stated differently, the probabilities <strong>of</strong> the S&P 500 returning<br />

between -7.99% and +7.99% are 98.64%.<br />

Pr<strong>of</strong>essor Jeremy Siegel adopts this idea. Siegel states, “The total return on equities dominates all other assets.” 5 Based on probabilities, we can be nearly certain<br />

that over the long-term, stocks will outperform bonds, gold, commodities, inflation, real estate, and other tradable investments.<br />

Are these ideas true? Are stock price movements effectively random? Do historical stock market returns indicate probabilities <strong>of</strong> future returns? Can statistical<br />

analysis tell us that the equities market will continue to outperform all other assets? Can stock market data never indicate that over a given period <strong>of</strong> time the market<br />

will increase at a rate greater than its historical gain? Can stock market data never point toward the probability <strong>of</strong> a decline overwhelming the probability <strong>of</strong> a<br />

rally?<br />

particles in radioactive decay, “may ultimately be understood in a deeper sense.”<br />

Roll <strong>of</strong> the Dice<br />

Let us compare the capital markets to a pair <strong>of</strong> dice, and the shooting <strong>of</strong> the double sixes to an investment in the equity market. Let us assume that beginning in<br />

the year 1900 only one pair <strong>of</strong> dice existed and all gamblers played with that dice. Let us assume that the dice were weighted and biased towards the shooting <strong>of</strong> the<br />

double six. Rather than the honest odds <strong>of</strong> 2.78% for the throwing <strong>of</strong> the double six, let us assume the odds were 5.00%. It is logical to assume that all those who<br />

bet on or against the double six would seek compensation commensurate with the perceived (but inaccurately considered) risk. After a few years however, some<br />

gamblers may begin to notice a statistical anomaly. It would seem as if the double six were favored. Those gamblers would seek to adjust to the perceived new reality.<br />

As more and more gamblers took notice, and accepted the fact that the dice are inherently biased, they will adjust their betting odds accordingly.<br />

Academics are, in fact, comparing the capital markets to those loaded dice. By studying historical market data, they have discovered the true nature <strong>of</strong> those<br />

dice. Ibbotson, Sinquefield, and Siegel can now state with certainty that stocks will outperform bonds and probabilistically return between +X% and -Y% over the<br />

next day, week, month or decade.<br />

It is not just members <strong>of</strong> academia who have discovered the positive bias <strong>of</strong> the stock market. Investors in general seem to compare the market to those<br />

inadvertently loaded dice as well. Historically, investors wrongly assumed that buying stocks was a risky endeavor. As compensation for taking that risk, investors<br />

in equities<br />

•<br />

Required a cash yield higher than that <strong>of</strong> long-term corporate bonds<br />

7<br />

Sought high absolute dividend yields<br />

8<br />

Invested only a small portion <strong>of</strong> their assets in stock<br />

9<br />

Limited their margin exposure<br />

6<br />

Not yet realizing that the capital markets (dice) were positively biased towards the equity market (double sixes), investors liquidated en masse when dividend<br />

yields declined or economic slowdowns materialized. Experiencing decade after decade <strong>of</strong> stocks outperforming bonds, investors have come to realize that the<br />

market compensates for the risks assumed. They no longer require stock yields to be greater than the bond yield. 10 They no longer require a high absolute dividend<br />

yield. 11 High long-term exposure to the equity market is common. 12 Investing on margin is an accepted norm. 13 Further confirming the market’s positive bias, the<br />

1987 crash passed with nary an effect, and the 2000-2003 Internet-stock implosion did not destroy well-diversified portfolios. The Dow, small-cap, mid-cap, and<br />

emerging markets worldwide continue making new, all-time highs. The wealth-creating machine continues running as expected. Investors know that over the longterm<br />

(measured in decades), stocks create wealth. Over the short-term (measured in days, months, and years), stock market direction is unpredictable!<br />

Statistics vs. <strong>Market</strong>s<br />

We disagree with the view <strong>of</strong> the academics, and deem the application <strong>of</strong> conventional statistical analysis to stock market prices as misguided. Stock market<br />

returns and risks cannot be compared to the probable outcomes <strong>of</strong> the throw <strong>of</strong> a pair <strong>of</strong> dice. 14 Nor can a bell-shaped curve generated by historical stock price<br />

movements be compared to the bell-shaped curve generated by a Quincunx board. 15 This is because an economic system is not the same as a physical system. In a<br />

physical system, predicted outcomes <strong>of</strong> dice rolls and Quincunx ball drops are true by definition. Trials or historic tests are not required to determine future outcomes.<br />

The probabilities <strong>of</strong> the outcomes are inherent within the nature <strong>of</strong> the object or system.<br />

In economic systems such as the Capital Asset Price Structure <strong>of</strong> the United States markets, there are no physical objects or material systems to analyze.<br />

Historical returns and risks may never be replicable. The structure is in a constant state <strong>of</strong> unrest. Economies based on capitalism can turn to socialism. Heavily<br />

regulated or protected industries can be liberalized. Thriving industries can virtually vanish due to foreign competition. Industries prosperous in a free environment<br />

may encounter excessive regulation or nationalization by a socialistically inclined Congress. Tax rates may be raised or lowered. The unit <strong>of</strong> account itself (the<br />

currency) may be recalibrated. The Federal Reserve may mismanage the supply <strong>of</strong> money and credit, transform mild recessions into deep depressions, or turn normal<br />

cyclical recoveries into credit based booms. In short, when measuring the capital markets, particularly the stock market, one is measuring the results <strong>of</strong> a myriad <strong>of</strong><br />

factors that may or may not repeat. Unique factors that may affect the markets in the future are not necessarily part <strong>of</strong> the historic system being measured.<br />

Most importantly, statistical analysis <strong>of</strong> stock prices does not measure any <strong>of</strong> the various financial statistics <strong>of</strong> the companies that make up the market. Nor does<br />

statistical analysis measure any <strong>of</strong> the economic and political factors that contribute to the wealth <strong>of</strong> the nation. All that is actually being measured are the prices<br />

that investors are paying for those economic entities. Prices paid for marketable securities are far removed from a physical or natural system suitable to the rigors <strong>of</strong><br />

statistical dissection.<br />

We therefore believe that based on statistical analysis one can only affirm that the stock market may or may not outperform bonds in the future or that stocks may<br />

or may not exhibit a long-term rising price trend in the future. We can only know with a certainty that stocks may or may not compensate investors for risk assumed,<br />

and we can have no idea where the market will trade one day, one week, one month, one year, or one decade from the present.<br />

We plainly disagree with Ibbotson, Sinquefield and Siegel, and do not recognize the ability to predict probabilities <strong>of</strong> stock market fluctuations. We take note that<br />

Nobel Prize winning economists portray the movement <strong>of</strong> stock prices as a random or drunkard’s walk. 16 Does this understanding <strong>of</strong> stock price movements mark<br />

the futility <strong>of</strong> technical market analysis?<br />

Paradox <strong>of</strong> Prediction<br />

In fact, were the movements <strong>of</strong> stock market prices to be <strong>of</strong> a random nature, the ultimate price trend may still be known and predictable in advance. This<br />

apparent paradox – that directionality can be predicted even if price movements were random – is based on a unique exception to the drunkard’s walk rule.<br />

The famed zoologist and writer Stephen Jay Gould gives the following example. “A man staggers out <strong>of</strong> a bar dead drunk. He stands on the sidewalk in front <strong>of</strong><br />

the bar, with the wall <strong>of</strong> the bar on one side and the gutter on the other. If he reaches the gutter he falls down into a stupor and the sequence ends. For simplicity’s<br />

sake, [and this example fits with the linear direction <strong>of</strong> stock price movement, either up or down] we will say that the drunk staggers in a single line only, either<br />

toward the wall or toward the gutter. He does not move at right angles along the sidewalk parallel to the wall and gutter.<br />

“Where will the drunkard end up if we let him stagger long enough and entirely at random? He will finish in the gutter absolutely every time and for the following<br />

reason: Each stagger goes in either direction with 50% probability. The bar wall at one side is a ‘reflecting boundary.’ If the drunkard hits the wall, he just stays there<br />

until a subsequent random stagger propels him in the other direction. In other words, only one direction <strong>of</strong> movement remains open for continuous advance – toward<br />

the gutter.<br />

“In a system <strong>of</strong> linear motion structurally constrained by a wall at one end, random movement, with no preferred directionality whatsoever, will inevitably propel<br />

the average position away from a starting point at the wall. The drunkard falls into the gutter every time, but his motion includes no trend whatever toward this form<br />

<strong>of</strong> perdition.” 17<br />

We posit that rigorous technical analysis can identify areas <strong>of</strong> “reflecting boundaries” in the capital markets. The direction <strong>of</strong> stock price movements can<br />

therefore be predicted in advance despite the perceived random nature <strong>of</strong> their daily and weekly moves.<br />

Graham & Dodd Meet <strong>Technical</strong> <strong>Analysis</strong><br />

Value investors admit that stock prices do not always reflect the many financial statistics <strong>of</strong> the companies they value. The only certainties that stock prices do<br />

reveal are the levels at which buyers and sellers have agreed to transact. 18 The discipline <strong>of</strong> value investing depends on this fact, that stock price fluctuations are<br />

not always value driven. Stock price movements must be radically independent <strong>of</strong> fluctuations in the value <strong>of</strong> the underlying entity in order for value investing to<br />

be effective. If stock prices always reflect the underlying value <strong>of</strong> a company, how could a company whose intrinsic value was $50 ever trade at $20? How could a<br />

company worth $50 ever trade at $100? How could a stock, or for that matter the market, ever be overpriced or undervalued?<br />

A more philosophical complexity is the following: If a stock appraised at $50 can be found to trade at $20, why can it not forever remain at $20? How can we<br />

be confident that this stock will return to intrinsic value? Why should a market that evaluates securities incorrectly be assumed to correctly price those very same<br />

securities in the future?<br />

Benjamin Graham was asked this very question. In testifying before Congress, Graham stated, “That is one <strong>of</strong> the mysteries <strong>of</strong> our business, and it is a mystery<br />

to me as well as to everybody else. We know from experience that eventually the market catches up with value.” 19<br />

Graham, the father <strong>of</strong> fundamental security analysis considered the philosophy behind his discipline to be a “mystery.” 20 By our understanding, value investing<br />

works because excessively low or high stock prices relative to intrinsic valuation serve as a technical indicator <strong>of</strong> the proximity <strong>of</strong> a reflecting boundary. That<br />

reflecting boundary exists at a price level and during a time period when many diverse fundamental and technical factors converge. Low valuation is one <strong>of</strong> the<br />

factors that can contribute to that reflecting boundary. Low valuation itself is not that boundary, for if it were, then levels <strong>of</strong> undervaluation that determine a bottom<br />

would remain consistent over time. However a stock or market may bottom at 40% <strong>of</strong> intrinsic value, at other times it may do so at 50% or 30% <strong>of</strong> intrinsic value.<br />

There must be other factors that combine to contribute to that reflecting boundary. We do not attempt to discover those factors. We use technical data to discover when<br />

and at what level these reflecting boundaries exist. In our view, the primary causes <strong>of</strong> stock price movements are too diverse, complex, and hidden to be analyzable.<br />

What we as technicians attempt to do is recognize the symptoms that lead and accompany directional movement <strong>of</strong> stock market prices.<br />

We posit that “reflecting boundaries” exist in the stock market. We do not know the nature <strong>of</strong> these reflecting boundaries. They are clearly not a predetermined<br />

boundary that can be measured and calculated. Nor are they fixed at a specific price level or calendar date. Their existence can at times be temporary, or very long<br />

lasting. There can be a single boundary or a series <strong>of</strong> boundaries at successively higher or lower prices. For reasons not knowable through direct analysis, these<br />

boundaries can cause stock prices to find support against further decline, or conversely they can cause stock prices to find resistance against further rally.<br />

Discovering the Boundaries<br />

Having theorized that stock price movements are generally random but are affected by boundaries <strong>of</strong> support and resistance, let us now reveal methods <strong>of</strong><br />

discovering those boundaries. Let us return to Chart 1, the five-day rate <strong>of</strong> change.<br />

This is a simple indicator, one that is based solely on price and time. Note that the curve generated by five-day rates <strong>of</strong> change is a standard curve. This fiveday<br />

data should pr<strong>of</strong>fer no predictive edge, and a statistician would conclude that these five-day rates <strong>of</strong> change are random. They are random in the sense that they<br />

cannot be predicted in advance. But where others perceive randomness, we take notice. Why would buyers be willing to pay 8-24% more for a diversified portfolio<br />

<strong>of</strong> stocks than they were willing to pay five days prior? Why would sellers be willing to accept 8-24% less than they were willing to receive five days prior? We do<br />

not care to know the answer. We care that it is a good question. We care that the action <strong>of</strong> those buyers and sellers are effectively aberrant.<br />

Our notion is that the only information that can be gleaned from stock prices is the willingness <strong>of</strong> investors to pay those prices. We therefore study the tails <strong>of</strong><br />

standard statistical curves and take note when they reflect anomalous behavior on the part <strong>of</strong> those who determine market prices. The specific times at which this<br />

action takes place cannot be predicted in advance, and their occurrence is effectively random. But those uncommon actions, when they do take place, signal the<br />

proximity <strong>of</strong> that “reflecting boundary.” When an apparent reflecting boundary has been hit by a myriad <strong>of</strong> buyers and sellers, the market inevitably propels away<br />

from that boundary.<br />

<strong>Technical</strong> indicators do not reveal causes <strong>of</strong> market movement. They simply indicate the proximity <strong>of</strong> a reflecting boundary. We therefore use technical indicators<br />

only in context <strong>of</strong> a potential reflective boundary. When creating models we utilize data only when they are proximate to a measured high or low, a potentially precise<br />

turning point.<br />

Using the five-day Rate <strong>of</strong> Change we eliminate all signals that are not proximate to potential and significant short term lows. Each signal date that is more than<br />

six days after the markets lowest low over the previous 90 days is therefore ignored. Additionally, we void <strong>of</strong> any thrust type indicator that signals just one to three<br />

days after a market low. We therefore eliminate any signal that flashes only one to three days after a 90 day low. This five-day ROC indicator then signals whenever<br />

the market has gained 8% or more over five days, as well as having made a new 90 day low within the previous four, five, or six days. See Appendix 2. 23<br />

Table 1 presents all <strong>of</strong> the final five-day +8% ROC signals.<br />

Recognizing the existence <strong>of</strong> reflecting boundaries and using price and time data alone, we have created an indicator in the S&P 500 Index that signaled within<br />

We have displayed the right tails <strong>of</strong> the five-day ROC curve. We have established that random movements <strong>of</strong> stock prices in conjunction with boundary analysis<br />

can be used to pinpoint proximate turning points. We now turn to the left tails <strong>of</strong> the same standard curve. Chart 3 displays an arrow each time the S&P 500 has<br />

declined 8% or more over a five-day period. See Appendix 3 for all signal dates.<br />

Chart 3<br />

Five-Day ROC -8%<br />

Note that these signals, which use a negative 8% parameter, <strong>of</strong>ten occur directly proximate a significant turning point.<br />

Using these -8% five-day ROC signal dates, we eliminate all signals that are not proximate to potential lows. We therefore include only those signals that take<br />

place as the market is trading at a maximum <strong>of</strong> one day 24 after a six month low. All signal dates that are two days or more after a six-month low are eliminated.<br />

Having utilized the two main legs <strong>of</strong> technical analysis, price and time, we will now introduce the third leg <strong>of</strong> technical analysis, volume. Five-day market<br />

volume can be represented by a standard curve, yet significant increases in market volume are not randomly distributed. The following (Chart 4) indicates each time<br />

the five-day average <strong>of</strong> daily volume was highest in 250 days. Out <strong>of</strong> 20,876 observations since 1929, there have been 425 instances (2.04% <strong>of</strong> total) <strong>of</strong> five-day<br />

average daily volume at a 250 day high. See Appendix 4 for all dates on which this occurred.<br />

We wonder why sellers would accept 8-24% less than they were willing to obtain five days prior. More importantly, we note that their urgency to sell (as reflected<br />

in the 250-day volume figures) increases dramatically as prices decline. In Table 2 we combine price, time and volume. Table 2 lists all periods during which both<br />

the five-day rate <strong>of</strong> decline was -8% or greater (price and time) and the five-day average <strong>of</strong> volume was highest within 250 days (time and volume). Additionally, in<br />

seeking indications <strong>of</strong> a technical reflecting boundary, we consider only those dates on which the price the sellers receive for their index <strong>of</strong> stocks was within one day<br />

<strong>of</strong> the lowest price they could have received during the previous six months (price and time). Results in Table 2 are compelling. By observing aberrations in price,<br />

time, and volume, we have created a viable capitulation-defining indicator.<br />

Table 2<br />

Five-Day ROC -8%<br />

Six Month Low<br />

250-Day Volume High<br />

This method can be refined further. We wait until a series <strong>of</strong> five-day 8% declines ends. Since we cannot know when that final day <strong>of</strong> a series occurs until a day<br />

after the series ends, we set our signal dates as one day after a -8% ROC extreme. To accommodate this adjustment we allow our buy signal to lag the 250-day volume<br />

boundary and the six-month low boundary by a maximum <strong>of</strong> seven days. (see table 3)<br />

Recognizing the existence <strong>of</strong> reflecting boundaries, and using price, volume and time alone, we have created an indicator in the S&P 500 Index that signaled<br />

within four-days <strong>of</strong> the historic lows <strong>of</strong>: November 13, 1929; October 19, 1987; July 23, 2002; and near the final low <strong>of</strong> June 26,1962.<br />

Last Signal in Series<br />

This concept that markets turn at reflecting boundaries permits the same indicators to call both tops and bottoms. It depends on whether those indicators are<br />

signaling at a potential top boundary or at a potential bottom boundary. An excellent example is the S&P 500 TRIN indicator.<br />

We consider a reading on the S&P 500 TRIN at or below .50 as representing extreme urgency to buy. Since 1957 there have been 530 (4.13% <strong>of</strong> total) days in<br />

which TRIN was at .50 or below. Looking at the five-day volume figures, we find that since 1957 there have been 240 instances (1.87% <strong>of</strong> total) in which the five-day<br />

average volume was highest in 375 days. (see appendix 5) When TRIN trades at or below.50 on a given day or on the previous day, and the five-day average volume<br />

is highest in 375 days on that day or on the previous day, we have an indicator suggestive <strong>of</strong> a potential market turn.<br />

If the market has traded at a new one-year low within the previous ten days (supportive boundary), we get a buy signal. See Table 4, and note that all seven<br />

signals resulted in long-term bull markets. (see chart appendix 6)<br />

If however the market is trading at a new three year high (potential top boundary) and during the previous five days TRIN traded at or below .50, and the<br />

five-day average volume was highest in 375 days within one day <strong>of</strong> the TRIN extreme, we get a sell signal. (see table 4a) Note that all signals led to bear markets.<br />

(see chart appendix 7)<br />

<strong>Technical</strong> <strong>Analysis</strong> Redefined<br />

Combining extremes in TRIN, volume, and proximity to potential reflective boundaries, creates an indicator that correctly identified seven major bull markets<br />

and four major bear markets. (see charts appendix 6 and 7)<br />

We have demonstrated that at significant turning points, the ultimate trend <strong>of</strong> the market can be predicted. We have introduced a new idea in technical analysis,<br />

the idea <strong>of</strong> “reflecting boundaries.” While in this paper we have demonstrated longer term boundaries, this idea can be used for the shorter term as well. This concept<br />

when used in conjunction with existing technical indicators can greatly assist the analyst in pinpointing market turning points. We hope this paper opens new<br />

possibilities for those who work at this mystifying discipline.<br />

Price & Volume, Digging Deeper<br />

Buff Dormeier, CMT<br />

2<br />

When securities change hands on a securities auction market, the volume <strong>of</strong> shares bought always matches the volume sold on executed orders. When the price<br />

rises, the upward movement reflects demand exceeds supply or that buyers are in control. Likewise, when the price falls it implies supply exceeds demand or that<br />

sellers are in control. Over time, these trends <strong>of</strong> supply and demand form accumulation and distribution patterns. What if there was a way to look deep inside price<br />

and volume trends to determine if current prices were supported by volume. This is the objective <strong>of</strong> the Volume Price Confirmation Indicator (VPCI), a methodology<br />

that measures the intrinsic relationship between price and volume.<br />

The Volume Price Confirmation Indicator or VPCI exposes the relationship between the prevailing price trend and the volume, as either confirming or<br />

contradicting the price trend, thereby giving notice <strong>of</strong> possible impending price movements. This paper discusses the derivation and components <strong>of</strong> the VPCI, and<br />

explains how to use the VPCI. We also review comprehensive testing <strong>of</strong> the VPCI, and presents further applications using the indicator.<br />

In exchange markets, price results from an agreement between buyers and sellers to exchange, despite their different appraisals <strong>of</strong> the exchanged item’s value.<br />

One opinion may have legitimate fundamental grounds for evaluation; the other may be pure nonsense. However, to the market, both are equal. Price represents the<br />

convictions, emotions and volition <strong>of</strong> investors. 1 It is not a constant, but rather is changed and influenced over time by information, opinions and emotions.<br />

<strong>Market</strong> volume represents the number <strong>of</strong> shares traded over a given time period. It is a measurement <strong>of</strong> the participation, enthusiasm, and interest in a given<br />

security. Volume can be thought <strong>of</strong> as the force that drives the market. Force or volume is defined as power exerted against support or resistance. 2 In physics, force<br />

is a vector quantity that tends to produce acceleration. 3 The same is true <strong>of</strong> market volume. Volume substantiates, energizes, and empowers price. When volume<br />

increases, it confirms price direction; when volume decreases, it contradicts price direction. In theory, increases in volume generally precede significant price<br />

movements. This basic tenet <strong>of</strong> technical analysis, that volume precedes price, has been repeated as a mantra since the days <strong>of</strong> Charles Dow. 4 Within these two<br />

independently derived variables, price and volume, exists an intrinsic relationship. When examined conjointly, price and volume give indications <strong>of</strong> supply and<br />

demand that neither could provide independently.<br />

The basic VPCI concept is derived by examining the difference between a volume-weighted moving price average (VWMAs) and the corresponding simple<br />

moving price average (SMA). These differences expose information about the inherent relationship between price and volume. Although, SMAs demonstrate a<br />

stock’s changing price levels, they do not reflect the amount <strong>of</strong> investor participation. On the other hand, with VWMAs, price emphasis is adjusted proportionally to<br />

each day’s volume, and then compared to the average volume over the range <strong>of</strong> study. The VWMA is calculated by weighting each time frame’s closing price with<br />

the time frame’s volume compared to the total volume during the range:<br />

volume-weighted average = sum {closing price (I) * [volume (I)/(total range)]} where I = given day’s action.<br />

This is an example <strong>of</strong> how to calculate a two-day moving average, using both the SMA and VWMA for a security trading at $10.00 a share with 100,000 shares<br />

changing hands on the first day, and at $12.00 a share with 300,000 shares changing hands on the second day. The SMA calculation is Day One’s price plus Day<br />

Two’s price divided by the number <strong>of</strong> days, or (10+12)/2, which equals 11. The VWMA calculation would be Day One’s price $10 multiplied by Day One’s volume<br />

which is expressed as a fraction <strong>of</strong> the total range: (100,000/400,000 = 1/4) plus Day Two’s price $12 multiplied by Day Two’s volume <strong>of</strong> the total range expressed<br />

as a fraction (300,000/400,000 = 3/4), which equals 11.5 (2.5 Day One + 9 Day Two) 5 .<br />

The VWMA measures investor’s commitments expressed through price, weighted by each day’s corresponding volume (participation), compared to the total<br />

volume (participation) over time. Thus, volume-weighted averages weight closing prices in exact proportion to the volume traded during each time period. Keeping<br />

in mind how VWMAs work, an investigation <strong>of</strong> the VPCI may begin.<br />

The VPCI involves three calculations:<br />

1) volume-price confirmation/contradiction (VPC+/-),<br />

2) volume-price ratio (VPR), and<br />

3) volume multiplier (VM).<br />

Deriving the Components<br />

VWMA volume-weighted moving average<br />

VPC (+/-) volume/price confirmation/contradiction<br />

VPR volume/price ratio<br />

VM volume multiplier<br />

The VPC is calculated by subtracting a long-term SMA from the same time frame’s VWMA. In essence, this calculation is the otherwise unseen nexus between<br />

price and price proportionally weighted to volume. This difference, when positive, is the VPC+ (volume-price confirmation) and, when negative, the VPC- (volumeprice<br />

contradiction). This computation is the intrinsic relationship between price and volume symmetrically distributed over time. The result is quite revealing. For<br />

example, a 50-day SMA might be $48.5, whereas the 50-day VWMA may be $50. The difference <strong>of</strong> 1.5 represents price-volume confirmation (VWMA – SMA). (see<br />

Chart 1) If the calculation were negative, then it would represent price-volume contradiction. This calculation alone provides purely unadorned information about<br />

the otherwise unseen relationship between price and volume.<br />

The next step is to calculate the volume price ratio (VPR). VPR accentuates the VPC+/- relative to the short-term price-volume relationship. The VPR is<br />

calculated by dividing the short-term VWMA by the short-term SMA. For example, assume the short-term timeframe is 10 days, and the 10-day VWMA is $68.75,<br />

while the 10-day SMA is $55. The VPR would equal 68.75/55, or 1.25. This factor will be multiplied by the VPC (+/-) calculated in the first step. Volume price ratios<br />

greater than 1 increase the weight <strong>of</strong> the VPC+/-. Volume-price ratios below 1 decrease the weight <strong>of</strong> the VPC+/-.<br />

The third and final step is to calculate the volume multiplier (VM). The VM’s objective is to overweight the VPCI when volume is increasing and underweight<br />

the VPCI when volume is decreasing. This is done by dividing the short-term average volume by the long-term average volume. As an illustration, assume SMA’s<br />

Jo u r n a l <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> • 2008 • Issue 65 19

Chart 1 VPC = VWMA- SMA<br />

short-term average volume for 10 days is 1.5 million shares a day, and the long-term average volume for 50 days is 750,000 shares per day. The VM equals 2<br />

(1,500,000/750,000). This calculation is then multiplied by the VPC+/- after it has been multiplied by the VPR. Now we have all the information necessary to<br />

calculate the VPCI. The VPC+ confirmation <strong>of</strong> +1.5 is multiplied by the VPR <strong>of</strong> 1.25, giving 1.875. Then 1.875 is multiplied by the VM <strong>of</strong> 2, giving a VPCI <strong>of</strong> 3.75.<br />

Although this number is indicative <strong>of</strong> an issue under very strong volume-price confirmation, this information serves best relative to the current and prior price trend<br />

and relative to recent VPCI levels. Next, we discuss how to properly use the VPCI.<br />

Using the VPCI<br />

We have previously expressed price as the emotion, conviction and volition <strong>of</strong> investors. Logically, we could then also define a price trend as the emotion,<br />

conviction and volition <strong>of</strong> investors expressed over time. Generally, a buyer’s underlying emotion or motivation is greed. Greed is the desire to obtain a pr<strong>of</strong>it. An<br />

uptrend could be viewed then as an accumulation <strong>of</strong> greed over time.<br />

Many times, but not always, an investor who creates supply, a seller, is motivated by the fear <strong>of</strong> losing value in his investment. Likewise, a downtrend would<br />

then be the accumulation <strong>of</strong> fear over time. We also spoke <strong>of</strong> volume as the force that sustains price. Force implies energy. A rising volume trend would represent a<br />

buildup in energy or fuel. A decrease in volume would then represent the loss <strong>of</strong> fuel, nonworking energy or entropy.<br />

Greed or an uptrend needs fuel to build and sustain itself. Greed’s growth cannot be sustained without energy. An investor will lose interest and move on to better<br />

opportunities. Whereas, an investor who is a seller, maybe bearish or fearful, but not necessarily. A seller could be motivated by greed and sell, allowing participation<br />

in a more lucrative investment. Or a seller could be motivated by greater emotions than greed, such as lust or personal responsibilities. In such cases, the investor will<br />

sell his investment to buy material pleasures or to satisfy his responsibilities. In this way greed (bulls) need fuel (volume) to expand but fear (bears) do not necessarily<br />

need volume to fall.<br />

Confirming Signals<br />

Several VPCI signals may be employed in conjunction with price trends and price indicators. These include a VPCI greater than zero, which shows whether he<br />

relationship between price trends and volume confirms or contradicts the price trend. 6 More importantly, a rising or falling VPCI, provides the trend direction <strong>of</strong> the<br />

VPCI, revealing the direction <strong>of</strong> confirmation or contradiction. And a smoothed volume-weighted average <strong>of</strong> VPCI called “VPCI smoothed” demonstrates how much<br />

the VPCI has changed from previous VPCI levels, and is used to indicate momentum. Bollinger Bands 7 maybe also applied to the VPCI, exposing VPCI extremes.<br />

Fundamentally, the VPCI reveals the proportional imbalances between price trends and volume-adjusted price trends. An uptrend with increasing volume is<br />

a market characterized by greed supported by the fuel needed to grow. An uptrend without volume is complacent and reveals greed deprived <strong>of</strong> the fuel needed to<br />

sustain itself. Investors without the influx <strong>of</strong> other investors (volume) will eventually lose interest and the uptrend should eventually breakdown.<br />

Chart 2 VPCI ‘V’ BOTTOM<br />

A falling price trend reveals a market driven by fear. A falling price trend without volume reveals apathy, fear without increasing energy. Unlike greed, fear is<br />

self-sustaining, and may endure for long time periods without increasing fuel or energy. Adding energy to fear can be likened to adding fuel to a fire and is generally<br />

bearish until the VPCI reverses. In such cases, weak-minded investor’s, overcome by fear, are becoming irrationally fearful until the selling climax reaches a state<br />

<strong>of</strong> maximum homogeneity. At this point, ownership held by weak investor’s has been purged, producing a type <strong>of</strong> heat death capitulation. These occurrences may<br />

be visualized by the VPCI falling below the lower standard deviation eight <strong>of</strong> a Bollinger Band <strong>of</strong> the VPCI, and then rising above the lower band, and forming<br />

a “V” bottom.<br />

22<br />

It’s important to note when using the VPCI that volume leads or precedes price action. Unlike most indicators, the VPCI will <strong>of</strong>ten give indications before price<br />

trends are clear. Thus, when a VPCI signal is given in an unclear price trend, it is best to wait until one is evident. At Point 1 in Chart 3, TM - Toyota Motor, is breaking<br />

out <strong>of</strong> a downtrend and the VPCI confirms this breakout immediately as the VPCI rises, crossing over the VPCI smoothed and then the zero line. This is an example <strong>of</strong><br />

VPCI’s bullish confirmation <strong>of</strong> a price trend. Later, the VPCI begins to fall during the uptrend, suggesting complacency. By Point 2, the VPCI crosses under the VPCI<br />

smoothed warning <strong>of</strong> a possible pause within the new uptrend. This is a classic example <strong>of</strong> a VPCI bearish contradiction. Before we reach Point 3, the VPCI makes an<br />

interesting pattern forming a “V” bottom. This is a bullish sign, <strong>of</strong>ten indicating the sell <strong>of</strong>f has washed out many <strong>of</strong> the sellers. Later at Point 3, the VPCI confirms the<br />

earlier bullish “V” pattern with a bullish crossover leading to a strong bull rally.<br />

Chart 4 The VPCI predicted the last major market pullback in May 2006<br />

Comparing the VPCI to other Price Volume Indicators<br />

There are many price volume indicators one could use to compare the VPCI to. However, the most acclaimed is Joe Granville’s original on-balance volume<br />

(OBV) indicator. 9 Recognizing volume as the force behind price, Granville, created OBV by assigning up days as positive volume (measured by an up close) and then<br />

subtracting volume on down days. OBV is price-directed volume, the accumulation <strong>of</strong> +/- volume flows based upon price direction. Granville’s original objective<br />

with on-balance volume was to uncover hidden coils in an otherwise non-eventful, non-trending market. 10 With his OBV indicator, Joe Granville, became a renowned<br />

market strategist. In so doing, he popularized OBV and the wisdom <strong>of</strong> using volume in securities analysis. Now, OBV is a standard application on charting s<strong>of</strong>tware<br />

and there are many OBV practitioners. However, few are able to interpret the indicators indications as competently as Granville.<br />

The VPCI differs from OBV in that it calculates the proportional imbalances between price trends and volume- weighted price trends. This exposes the influence<br />

volume has upon a price trend. Although both contain volume- derived data, they convey different information. In composition, the VPCI is not an accumulation<br />

<strong>of</strong> history like OBV but rather a snapshot <strong>of</strong> the influence <strong>of</strong> volume upon a price trend over a specified period <strong>of</strong> time. This enables the VPCI to give faster signals<br />

than accumulation indicators similar to an oscillator. In contrast to OBV, the VPCI’s objective is not to uncover hidden coils in trendless markets, but to evaluate the<br />

health <strong>of</strong> existing trends.<br />

Comparing the VPCI to OBV<br />

To illustrate the effectiveness and proper use <strong>of</strong> the VPCI, a test was conducted comparing the VPCI to OBV. The most general VPCI buy signal is when the<br />

VPCI crosses above the VPCI smoothed in an up-trending market. This indicates the VPCI is rising relative to previous VPCI levels. The traditional OBV does not<br />

have a lagging trigger like the VPCI smoothed, so I amended the OBV by adding an additional eight-period simple moving average <strong>of</strong> OBV. The net effect gives<br />

OBV a corresponding trigger to the VPCI smoothed. OBV crossovers <strong>of</strong> OBV smoothed would give indications <strong>of</strong> OBV rising relative to previous OBV levels.<br />

Remember, VPCI is designed to be used in a trending market, with a trending indicator. Thus we need two additional tools to complete this test. First, we’ll need<br />

an indicator to verify whether or not we are in a trending market. A seven-period ADX (Average Directional Index by Welles Wilder) indicator fulfills this criterion<br />

by indicating an intense trend when ADX equals or is greater than 30. 11 Next, we will need a trend indicator to show the trend’s direction. Gerald Appel’s MACD<br />

(Moving Average Convergence Divergence) with the traditional (12, 26, 9) settings was used to provide buy entry signals for this test. 12 Finally, we will need a<br />

test subject which illustrates how these indicators work across a broad market. I can think <strong>of</strong> no better or popular vehicle for this experiment than the SPDR S&P<br />

500; exchange traded fund. The testing period was conducted from inception (February, 1993) until the end <strong>of</strong> 2006. Standard specifications were used on both<br />

indicators (OBV – 20 day and VPCI 5/20 {5 day short-term trend & 5*4 day long-term trend}). Results were not optimized in any way. (Please note that the examples<br />

provided are for informational purposes only. This is in no way a solicitation or <strong>of</strong>fer to the fore mentioned security.) In this system, long positions are taken only<br />

when the above conditions are met when accompanied by OBV crossovers in the first test, or by VPCI crossovers in the second test. Long positions are exited with<br />

crossunders <strong>of</strong> OBV smoothed in the first test or with VPCI crossunders in the second study. Although this test was created rather simplistically and traditionally for<br />

both observational and creditability purposes, the results are quite stunning.<br />

Chart 7 SPY: The VCPI Equity Curve<br />

Excluding dividends or interest, OBV’s annualized rate <strong>of</strong> return in the above system was -1.57%, whereas the VPCI’s annualized return was 8.11%, an outperformance<br />

<strong>of</strong> over 9.5% annualized. The VPCI improved reliability, giving pr<strong>of</strong>itable signals over 65 percent <strong>of</strong> the time, compared to OBV at only 42.86 percent.<br />

Another consideration in evaluating performance is risk. The VPCI had less than half the risk as measured by volatility, 7.42 standard deviations compared to OBV<br />

with 17.4 standard deviations from the mean. It is not surprising, then that the VPCI had much better risk adjusted rates <strong>of</strong> return. The VPCI’s Sharpe Ratio from<br />

inception was .70 and had a pr<strong>of</strong>it factor <strong>of</strong> 2.47, compared to OBV with a -0.09 Sharpe Ratio and a pr<strong>of</strong>it factor <strong>of</strong> less than 1. Admittedly, this testing environment<br />

is an uneven match. The VPCI uses information from volume-weighted prices to gauge the health <strong>of</strong> existing trends, whereas OBV accumulates volume flows as<br />

directed by price changes to uncover hidden coils. Thus the conditions setup in this system, a trending market with apparent price direction, is one in which the<br />

VPCI is designed to succeed. Although, OBV was not necessarily setup for failure either, this study does illustrate how less savvy practitioners <strong>of</strong>ten fail to use the<br />

indicators’ information correctly or fail to coordinate the indicators properly.<br />

Table 2 Comparing Strategies’ Returns<br />

What if an investor had just used the MACD buy and sell signals within this same system, without utilizing the VPCI information? In this example, this investor<br />

would have lost out on nearly 12% annualized return, the difference between the VPCI’s positive 8.11% versus the MACD’s negative -3.88% rate <strong>of</strong> return, while<br />

significantly increasing risk. What if this investor had just employed a buy-and-hold approach? Although this investor would have realized a slightly higher return,<br />

he/she would have been exposed to much greater risks. The VPCI strategy returned nearly 90% <strong>of</strong> the buy-and-hold strategy return while avoiding about 60%<br />

less risk as measured by standard deviation. Looking at risk-adjusted returns another way, the five year Sharpe Ratio for the SPDR 500 was only .1 compared to<br />

the VPCI system <strong>of</strong> .74. Additionally, the VPCI investor would have been invested only 35% <strong>of</strong> the time, allowing the investor the opportunity to invest in other<br />

investments. During the 65% <strong>of</strong> the time the investor was not invested, he/she would have only needed a 1.84% money-market yield to exceed the buy-and-hold<br />

strategy. Moreover, this investor would have experienced a much smoother performance, without such precipitous capital draw downs. The worst annualized VPCI<br />

return was only a measly -2.71% compared to the underlying investments worst year <strong>of</strong> -22.81%, more than 20% difference in the rate <strong>of</strong> return! If an investor had<br />

invested in a money-market instrument, while not invested in the SPDR S&P 500, this VPCI strategy would not have experienced a single down year.<br />

Table 3 Annual Returns by Year<br />

Other Applications<br />

Further testing not covered in this research report suggests the VPCI may be used broadly across most markets exhibiting clear and reliable price and volume<br />

data such as individual equities, exchange traded funds, and broad indices. The raw VPCI calculation may also be used as a multiplier or divider in conjunction<br />

with other indicators, such as moving averages, momentum indicators, or raw price and volume data. For example, if an investor has a trailing stop loss order set<br />

at the five-week moving average <strong>of</strong> the lows, one could divide the stop price by the VPCI calculation. This would lower the price stop when price and volume are<br />

in confirmation, increasing the probability <strong>of</strong> keeping an issue under accumulation. However, when price and volume are in contradiction, dividing the stop loss by<br />

the VPCI would raise the stop price, preserving more capital. Similarly, using VPCI as a multiplier to other price, volume, and momentum indicators may not only<br />

improve reliability but it could increase responsiveness as well.<br />

Conclusion<br />

The VPCI reconciles volume and price as determined by each <strong>of</strong> their proportional weights. This information may be used to deduce likelihood <strong>of</strong> a current<br />

price trend continuing or reversing. I believe this study clearly demonstrates that adding the VPCI indicator to a trend-following system resulted in consistently<br />

improved performance across all major areas measured by the study. It is my opinion that in the hands <strong>of</strong> a pr<strong>of</strong>icient investor, the Volume Price Confirmation<br />

Indicator is a capable tool providing information which may be useful in potentially accelerating pr<strong>of</strong>its, reducing risk and empowering the investor towards sound<br />

investment decisions.<br />

Inferring Trading Strategies From Probability Distribution Functions<br />

John Ehlers<br />

Background<br />

Jo u r n a l <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> • 2008 • Issue 65<br />

3<br />

The primary purpose <strong>of</strong> technical analysis is to observe market events and tally their consequences to formulate predictions. In this sense market technicians are<br />

dealing with statistical probabilities. In particular, technicians <strong>of</strong>ten use a type <strong>of</strong> indicator known as an oscillator to forecast short-term price movements.<br />

An oscillator can be viewed as a high pass filter in that it removes lower frequency trends while allowing the higher frequencies components, i.e., short-term<br />

price swings to remain. On the other hand, moving averages act as a low pass filters by removing short-term price movements while permitting longer-term trend<br />

components to be retained. Thus moving averages function as trend detectors whereas oscillators act in an opposite manner to “de-trend” data in order to enhance<br />

short term price movements. Oscillators and moving averages are filters that convert price inputs into output waveforms to magnify or emphasize certain aspects <strong>of</strong><br />

the input data. The process <strong>of</strong> filtering necessarily removes information from the input data and its application is not without consequences.<br />

A significant issue with oscillators (as well as moving averages) for short term trading is that they introduce lag. While academically interesting, the consequences<br />

<strong>of</strong> lag are costly to the trader. Lag stems from the fact that oscillators by design are reactive rather than anticipatory. As a result, traders must wait for confirmation;<br />

a process that introduces additional lag into the ability to take action. It is now widely accepted that classical oscillators can be very accurate in hindsight but are<br />

typically inadequate for forecasting future short-term market direction, in large part due to lag.<br />

Probability Distribution Functions<br />

The basic shortcoming <strong>of</strong> classical oscillators is that they are reactive rather than anticipatory. As a result, the undesirable lag component in oscillators significantly<br />

degrades their usefulness as a tool for pr<strong>of</strong>itable short-term trading. What is needed is an effective mechanism for anticipating turning points.<br />

The Probability Distribution Function (PDF) can be borrowed from the field <strong>of</strong> statistics and used to examine detrended market prices for the purpose <strong>of</strong> inferring<br />

trading strategies. The PDF <strong>of</strong>fers an alternative approach to the classical oscillator; one that is non-causal in anticipating short-term turning points.<br />

PDFs place events into “bins” with each bin containing the number <strong>of</strong> occurrences in the y-axis and the range <strong>of</strong> events in the x-axis. For example, consider the<br />

square wave shown in Figure 1A. Although unrealistic in the real world, if one were to envision the square wave as “quantum” prices that can only have values <strong>of</strong><br />

-1 or +1, the resultant PDF consists simply <strong>of</strong> two vertical “spikes” at -1 and +1 as shown in Figure 1B. Such a waveform could not be traded using conventional<br />

oscillators because any price movement would be over before the oscillator could yield a signal. However as the PDFs below will show, the theoretical square wave<br />

is not far removed from real-world short term cycles.<br />

As a practical example, a theoretical sine wave can be used to more accurately model real-world detrended prices. An idealized sinewave is shown in Figure 1C<br />

and its corresponding PDF in Figure 1D. The PDFs <strong>of</strong> the square wave and that <strong>of</strong> the sine wave are remarkably similar. In each case there is a high probability <strong>of</strong><br />

the waveforms being near their extremes as can be seen in the large spikes in Figure 1D. These spikes correspond to short-term turning points in the detrended prices.<br />

The probability is high near the turning points because there is very little price movement in these phases <strong>of</strong> the cycle, with prices ranging only from about 0.8 to 1.0<br />

and -0.8 to -1.0 in Figure 1C.


The high probability <strong>of</strong> short term prices being near their extreme excursions is a principal difficulty in short-term cycle and swing trading. The move has<br />

mostly occurred before the oscillators can identify the turning point. The indicator “works” but only in hindsight limiting its usefulness for predicting future price<br />

movements.<br />

A possible solution to this lag dilemma is to develop techniques to anticipate turning points. Although exceedingly difficult to accomplish with classical<br />

oscillators, the PDF affords us the opportunity to anticipate turning points if properly shaped or to use two alternative methods:<br />

1. Model the market data as a sine wave and shift the modeled waveform into the future by generating a leading cosine wave from it.<br />

2. Apply a transform to the detrended waveform to isolate the peak excursions, i.e., rare occurrences – and anticipate a short-term price reversion from the peak.<br />

Each <strong>of</strong> these approaches will be examined below. However it is instructive to begin with an analogy for visualizing a theoretical sine wave PDF and then<br />

examine PDFs <strong>of</strong> actual market data. As will be shown, market data PDFs are neither Gaussian as commonly assumed nor random as asserted by the Efficient <strong>Market</strong><br />

Hypothesis.<br />

Measuring Probability Distribution Functions<br />

An easy way to visualize how a PDF is measured as in figure 2B is to envision the waveform as beads strung on parallel horizontal wires on vertical frames as<br />

shown in Figure 2A. Rotate the wire-frame clockwise 90 degrees (1/4 turn) so the horizontal wires are now vertical allowing the beads to fall to the bottom. The<br />

beads stack up in Figure 2B in direct proportion to their density at each horizontal wire in the waveform with the largest number <strong>of</strong> occurrences at the extreme turning<br />

points <strong>of</strong> +1 and -1.<br />

Measuring PDFs <strong>of</strong> detrended prices using a computer program is conceptually identical to stacking the beads in the wireframe structure. The amplitude <strong>of</strong> the<br />

detrended price waveform is quantized into “bins” (i.e. the vertical wires) and then the occurrences in each bin are summed to generate the measured PDF. The prices<br />

are normalized to fall between the highest point and the lowest point within the selected channel period.<br />

Figure 3 shows actual price PDFs measured over thirty years using the continuous contract for US Treasury Bond Futures. Note that the distributions are similar<br />

to that <strong>of</strong> a sine wave in each case. The non-uniform shapes suggest that developing short term trading systems based on sine wave modeling could be successful.<br />

Normalizing prices to their swings within a channel period is not the only way to detrend prices. An alternative method is to sum the up day closing prices<br />

independently from down days. That way the differential <strong>of</strong> these sums can be normalized to their sum. The result is a normalized channel, and is the generic form<br />

<strong>of</strong> the classic RSI indicator. The measured PDF using this method <strong>of</strong> detrending <strong>of</strong> the same 30 years <strong>of</strong> US Treasury Bonds data is shown in Figure 4. In this case,<br />

the PDF is more like the familiar bell-shaped curve <strong>of</strong> a Gaussian PDF. One could conclude from this that a short-term trading system based on cycles would be less<br />

than successful as the high probability points are not near the maximum excursion turning points.<br />

Jo u r n a l <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> • 2008 • Issue 65 27

Because the turning points have relatively low probability an alternate strategy can be inferred. The idea is to buy when the detrended price crosses below a<br />

threshold near the lower bound in anticipation <strong>of</strong> the prices reversing to higher probability territory. Similarly, the strategy would sell when the detrended price<br />

crosses above a threshold near the upper bound. Note that this is not the same as using classical 30/70 or 20/80 thresholds for signals with the RSI because signal is<br />

not waiting for confirmation crossing back across the thresholds. Here we are anticipating a reversal to a higher probability occurrence – we expect a reversion to<br />

normalcy. Using this anticipatory method in the case <strong>of</strong> a classic indicator such as the Stochastic oscillator can be costly because the Stochastic can easily remain at<br />

the extreme excursion point (or “rail” in engineering parlance) for long periods <strong>of</strong> time.<br />

As previously mentioned, another way to detrend the price data is to use high pass filter to remove its lower frequency trend components. Once detrended, the<br />

result must be normalized to a fixed excursion so that it can be properly binned before applying the PDF. The resulting PDF is shown in Figure 5. In this case, the<br />

PDF shape is nearly uniform across all bins. A uniform PDF means the amplitude in one bin is just as likely to occur as another. In this case neither a cycles-based<br />

strategy nor a strategy based on low probability events could be expected to be successful. The PDF must somehow be transformed to enhance low probability events<br />

in order to be useful in trading.<br />

Transforming the PDF<br />

Not all detrending techniques yield PDFs that suggest a successful trading technique. In much the same way that an oscillator can be applied to price data to<br />

enhance short-term turning points, a transformation function can be applied to the detrended prices to enhance identification <strong>of</strong> “black swan,” i.e., highly unlikely<br />

events and to develop successful trading strategies based on predicting a reversion back to normalcy following a black swan event.<br />

For example, a PDF can be enhanced through the use <strong>of</strong> the Fisher Transform. This mathematical function alters input waveforms varying between the limits<br />

<strong>of</strong> -1 and +1 transforming almost any PDF into a waveform that has nearly Gaussian properties. The Fisher Transform equation, where x is the input and y is<br />

the output is:<br />

Unlike an oscillator, the Fisher Transform is a nonlinear function with no lag. The transform expands amplitudes <strong>of</strong> the input waveforms near the -1 and +1<br />

excursions so they can be identified as low probability events. As shown in Figure 6 the transform is nearly linear when not at the extremes. In simple terms, the<br />

Fisher Transform doesn’t do anything except at the low-probability extremes. Thus it can be surmised that if low probability events can be identified, trading<br />

strategies can be employed to anticipate a reversion to normal probability after their occurrence.<br />

Jo u r n a l <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> • 2008 • Issue 65


The effect <strong>of</strong> the Fisher Transform is demonstrated by applying it to the HighPass Filter approach that produced the PDF in Figure 5. The output is rescaled for<br />

proper binning to generate the new measured PDF. The new measured PDF is displayed in Figure 7, with the original PDF shown in the inset for reference. Here<br />

we have a waveform that suggests a trading strategy using the low probability events. When the transformed prices exceed an upper threshold the expectation is<br />

that staying beyond that threshold has a low probability. Therefore, exceeding the upper threshold presents a high probability selling opportunity. Conversely, when<br />

the transformed prices fall below a lower threshold the expectation is that staying below that threshold is a low probability and therefore falling below the lower<br />

threshold presents a buying opportunity.<br />

Derived Trading Strategies<br />

It is clear that no single short term trading strategy is suitable for all cases because the PDFs can vary widely depending on the detrending approach. Since the<br />

PDF <strong>of</strong> data detrended by normalizing to peak values has the appearance <strong>of</strong> a theoretical sinewave, the logical trading strategy would be to assume the waveform<br />

is, in fact, a sine wave and then identify the sine wave turning points before they occur. On the other hand, data that is detrended using a generic RSI approach or is<br />

detrended using a HighPass filter with a Hilbert Transform should use a trading strategy based on a more statistical approach. Thus, for the RSI and Hilbert Transform<br />

approaches, the logical strategy consists <strong>of</strong> buying when the detrended prices cross below a lower threshold and selling when the detrended prices cross above an<br />

upper threshold. Although somewhat counterintuitive, this second strategy is based on the idea that prices outside the threshold excursions are low probability events<br />

and the most likely consequence is that the prices will revert to the mean.<br />

Both short term trading strategies share a common problem. The problem is that the detrending removes the trend component, and the trend can continue rather<br />

than having the prices revert to the mean. In this case, a short term reversal is exactly the wrong thing to do. Therefore an additional trading rule is required. The rule<br />

added to the strategies is to recognize when the prices have moved opposite to the short term position by a percentage <strong>of</strong> the entry price. If that occurs, the position<br />

is simply reversed and the new trade is allowed to go in the direction <strong>of</strong> the trend.<br />

The “Channel” Cycle Strategy finds the highest close and the lowest close over the channel length by computing a simple search algorithm over a fixed lookback<br />

period. Then, the detrended price is computed as the difference between the current close and the lowest close, normalized to the channel width. The channel width<br />

is the difference between the highest close and the lowest close over the channel length. The detrended price is then BandPass filtered 1 to obtain a near sine wave<br />

from the data whose period is the channel length. From the calculus it is known that d(Sin(ωt))/dt =ωCos(ωt). Since a simple one bar difference is a rate-change, it is<br />

roughly equivalent to a derivative. Thus, an amplitude corrected leading function is computed as the one bar rate <strong>of</strong> change divided by the known angular frequency.<br />

In this case, the angular frequency is 2π divided by the channel length. Having the sine wave and the leading cosine wave, the major trading signals are the crossings<br />

<strong>of</strong> these two waveforms. The strategy also includes a reversal if the trade has an adverse excursion in excess <strong>of</strong> a selected percentage <strong>of</strong> the entry price.<br />

The Generic “RSI” Strategy sums the differences in closes up independently from the closes down over the selected RSI length. The RSI is computed as the<br />

differences <strong>of</strong> these two sums, normalized to their sum. A small amount <strong>of</strong> smoothing is introduced by a three tap FIR filter. The main trading rules are to sell short if<br />

Smoothed Signal crosses above the upper threshold and to buy if Smoothed Signal crosses below the lower threshold. As before, the strategy also includes a reversal<br />

if the trade has an adverse excursion in excess <strong>of</strong> a selected percentage <strong>of</strong> the entry price.<br />

The High Pass Filter plus Fisher Transform (“Fisher”) strategy filters the closing prices in a high pass filter. 2 The filtered signal is then normalized to fall between<br />

-1 and +1 because this range is required for the Fisher Transform to be effective. The normalized amplitude is smoothed in a three tap FIR filter. This smoothed<br />

signal is limited to be greater than -.999 and less than +.999 to avoid having the Fisher Transform blow up if its input is exactly one. Finally, the Fisher Transform<br />

is computed. The main trading rules are to sell short if the Fisher Transform crosses above the upper threshold and to buy if the Fisher Transform crosses below the<br />

lower threshold. As before, the strategy also includes a reversal if the trade has an adverse excursion in excess <strong>of</strong> a selected percentage <strong>of</strong> the entry price.<br />

The three trading strategies were applied to the continuous contract <strong>of</strong> US Treasury Bond Futures for data five years prior to 12/7/07. The performance <strong>of</strong> the<br />

three systems is summarized in Table 1. All three systems show respectable performance, with the RSI strategy and Fisher strategy having similar performance<br />

with respect to percentage <strong>of</strong> pr<strong>of</strong>itable trades and pr<strong>of</strong>it factor (gross winnings divided by gross losses). All results are based on trading a single contract with no<br />

allowance for slippage and commission. It is emphasized that all settings were held constant over the entire five year period. Since the trading strategies have only<br />

a small number <strong>of</strong> optimizable parameters, optimizing over a shorter period is possible without compromising a trade-to-parameter ratio requisite to avoid curve<br />

fitting. Thus, performance can be enhanced by optimizing over a shorter time span.<br />

Annualized performance <strong>of</strong> the trading strategies was assessed by applying the real trades over the five year period to a Monte Carlo analysis for 260 days,<br />

an approximate trading year. In each case the Monte Carlo analysis used 10,000 iterations, simulating nearly 40 years <strong>of</strong> trading. S<strong>of</strong>tware to do this analysis was<br />

MCSPro 3 by Inside Edge Systems. Due to the central limit theorem, the probability distribution <strong>of</strong> annual pr<strong>of</strong>it has a Normal Distribution and the Drawdown has a<br />

Rayleigh Distribution. While the Monte Carlo analysis reveals the most likely annual pr<strong>of</strong>its and drawdowns, it can also assess the probability <strong>of</strong> breakeven or better.<br />

Furthermore, one can make a comparative reward/risk ratio by dividing the most likely annual pr<strong>of</strong>it by the most likely annual drawdown. One can also evaluate the<br />

amount <strong>of</strong> tolerable risk and required capitalization in small accounts from the size <strong>of</strong> the two or three sigma points in the drawdown.<br />

The Monte Carlo results for the Channel strategy are shown in Figure 8. The most likely annual pr<strong>of</strong>it is $11,650 and the most likely maximum drawdown is<br />

$7,647 for a reward to risk ratio <strong>of</strong> 1.52. The Channel strategy has an 88.3% chance <strong>of</strong> break even or better on an annualized basis.<br />

The Monte Carlo results for the RSI strategy are shown in Figure 9. The most likely annual pr<strong>of</strong>it is $17,085 and the most likely maximum drawdown is $6,219.<br />

Since the pr<strong>of</strong>it is higher and the drawdown is lower than for the Channel strategy, the reward to risk ratio is much larger at 2.75. The RSI strategy also has a better<br />

96.6% chance <strong>of</strong> break even or better on an annualized basis.<br />

The Monte Carlo results for the Fisher strategy are shown in Figure 10. The most likely annual pr<strong>of</strong>it is $16,590 and the most likely maximum drawdown is<br />

$6,476. The reward to risk ratio <strong>of</strong> 2.56 is about the same as for the RSI strategy. The Fisher Transform strategy also has about the same chance <strong>of</strong> break even or<br />

better at 96.1%.<br />

These studies show that the three trading strategies are robust across time and <strong>of</strong>fer comparable performance when applied to a common symbol. To further<br />

demonstrate robustness across time as well as applying to a completely different symbol, performance was evaluated on the S&P Futures, using the continuous<br />

contract from its inception in 1982. In this case, we show the equity curve produced by trading a single contract without compounding. There is no allowance for<br />

slippage and commission. The shape <strong>of</strong> the equity curves are explained, in part, by the change <strong>of</strong> the point size from $500 per point to $250 per point, by inflation,<br />

by the increasing absolute value <strong>of</strong> the contract, and by increased volatility. The major point is that none <strong>of</strong> the three trading strategies had significant dropouts in<br />

equity growth over the entire lifetime <strong>of</strong> the contract.<br />

The robust performance <strong>of</strong> these new trading strategies are particularly striking when compared to more conventional trading strategies. For example, Figure 14<br />

shows the equity growth <strong>of</strong> a conventional RSI trading system that buys when the RSI crosses over the 20% level and sells when the RSI crosses below the 80 %<br />

level. This system also reverses position when the trade has an adverse excursion more than a few percent from the entry price. This conventional RSI system was<br />

optimized for maximum pr<strong>of</strong>it over the life <strong>of</strong> the S&P Futures Contract. Not only has the conventional RSI strategy had huge drawdowns, but its overall pr<strong>of</strong>it factor<br />

was only 1.05. Any one <strong>of</strong> the new strategies I have described <strong>of</strong>fers significantly superior performance over the contract lifetime. This difference demonstrates the<br />

efficacy <strong>of</strong> the approach and the robustness <strong>of</strong> these new systems.<br />

Conclusions<br />

The PDF has been shown to <strong>of</strong>fer an alternative approach to the classical oscillator, one that is non-causal in anticipating short-term turning points.<br />

Several specific trading strategies have been presented that demonstrate robust performance across long timespans to accommodate varying market conditions;<br />

across a large number <strong>of</strong> trades to avoid curve fitting; and among different markets to demonstrate freedom from market personalities.<br />

In each case the PDF can infer a trading strategy that is likely to be successful. When no strategy is suggested, the Fisher Transform can be applied to change<br />

the PDF to a Gaussian distribution. The Gaussian PDF then infers that a trading strategy using a reversion to the mean can be successful.<br />

An Empirical Study <strong>of</strong> Rotational Trading Using the %b Oscillator<br />

H. Parker Evans, CFA, CFP, CMT<br />

Introduction<br />

4<br />

Academic finance is replete with studies supporting or denying the existence <strong>of</strong> serial correlation in securities prices. 1 In effect, such studies test the weak form<br />

efficient market hypothesis (EMH). Simply put, can investors use technical analysis to beat the market?<br />

Before an attempt is made to answer that question, it is necessary to define “the market.” For the purposes <strong>of</strong> this paper, “the market” is the constituent stocks<br />

<strong>of</strong> the S&P 500 Index. The S&P 500 Index, after all, is probably the most widely recognized market proxy and in practice, investors index billions <strong>of</strong> dollars to it.<br />

S&P 500 stocks are liquid and extensively researched by a multitude <strong>of</strong> technical and fundamental analysts. Consequently, one might expect that these stocks would<br />

represent a highly efficient segment <strong>of</strong> the stock market.<br />

Bollinger Bands and the %b Oscillator<br />

The %b Oscillator is a technical indictor derived from the well-known, popular Bollinger Bands indicator. “Bollinger Bands are a technical trading tool created<br />

by John Bollinger in the early 1980s. They arose from the need for adaptive trading bands and the observation that volatility was dynamic, not static as was widely<br />

believed at the time.” 2 Bollinger bands are moving average envelopes typically plotted two standard deviations above and below a moving average <strong>of</strong> price closes. In<br />

an end-<strong>of</strong>-day price chart, %b plots as an oscillator, measuring the closing price in relation to its upper and lower Bollinger Band. An analogous technical indicator<br />

is the raw stochastic %K oscillator. 3 Raw %K measures the closing price relative to the high and low price <strong>of</strong> a trading range <strong>of</strong> specified length. By definition, %K<br />

oscillates between 0 and 100. Zero means the stock closed at the low <strong>of</strong> the trading range, 100 means the stock closed at the high. Likewise for %b, except that on<br />

rare occasions a stock can close with %b below 0 or above 100, representing a two-sigma event. Conceptually, %b numerically identifies the closing stock price<br />

relative to its volatility-adjusted trading range.<br />

In Figure 1, the dprice chart for Wal-Mart stock (WMT) covers five years <strong>of</strong> daily high-low-close prices. In the top pane, is plotted a simple 65-day moving<br />

average <strong>of</strong> closing prices represented by the middle blue line. The related Bollinger Bands are plotted in red, exactly two-sigma above and below the middle blue<br />

moving average line. In the bottom pane, plot %b is plotted as an oscillator. Here %b is defined as overbought when it is greater than 90 and oversold when less than<br />

10. The overbought %b condition is highlighted in red and oversold is highlighted in green.<br />

Rotational Trading<br />

Rotational trading is a method <strong>of</strong> using rank-ordered asset lists to construct investment portfolios. For example, both Value Line and Zacks Investment Research<br />

<strong>of</strong>fer well-known research products featuring proprietary stock timeliness rankings. These services assign a rank, one to five, to each asset in their coverage universe.<br />

Using these rankings, a rotational system might buy stocks ranked #1, sell when they drop below rank #2, and rotate those proceeds back into stocks ranked #1. For<br />

many years, Investor’s Business Daily has published proprietary relative strength rankings for stocks ranging from one to ninety-nine. Such increased granularity is<br />

useful for active rotational trading, as will be demonstrated further on.<br />

As always, a complete trading system must address position sizing and answer: What percentage risk <strong>of</strong> total portfolio equity can be exposed on any given<br />

trade or asset?<br />

Portfolio Selection Using Relative %b<br />

The basis for using %b as a momentum oscillator stems from the empirical observation that extreme price excursions have a tendency for mean reversion,<br />

i.e. possible negative serial correlation. In <strong>Technical</strong> <strong>Analysis</strong> Explained (Pring, Martin J., McGraw-Hill, 2002), Martin Pring warned against relying solely on<br />

momentum oscillators when analyzing individual securities. “Momentum signals should always be used in conjunction with a trend reversal signal by the actual<br />

price.” This paper will test the opposite idea within a portfolio context. We will boldly buy weakness and sell strength without waiting for evidence <strong>of</strong> a reversal<br />

in price. To mix metaphors, the strategy will systematically “catch the falling knife” and sell the “dead cat” bounce without regard to any other technical indicator.<br />

Specifically the trading algorithm will buy stocks with the very lowest %b ranks and sell when they increase rank relative to other stocks. Understand that a portfolio<br />

<strong>of</strong> stocks will be bought that have the lowest %b relative to all other stocks in a specified selection universe.<br />

In <strong>Technical</strong> <strong>Analysis</strong> from A to Z (Achelis, Steven B. Chicago: Irwin, 1995), John Bollinger states, “When prices move outside the bands, a continuation <strong>of</strong> the<br />

current trend is implied.” Because a reasonable observer could interpret this rule as a contradiction to what we propose to test, we will also consider what happens<br />

if we reverse our trading rule, buying strong stocks with the very highest %b (presumably stocks “outside the band”) and selling only when they drop in rank.<br />

Now to answer the original question, by using the %b oscillator coupled with rotational trading rules, we can select stock portfolios that beat the risk-adjusted<br />

return <strong>of</strong> the S&P 500 index. We report empirical evidence supporting this thesis later in the results section <strong>of</strong> this paper. In addition, an important purpose <strong>of</strong> this<br />

paper is to provide sufficient detail to allow other analysts to replicate our (back-tested) results and to modify or adapt our methods if desired. That detail comes next<br />

in the methods and materials section <strong>of</strong> this paper.<br />

Methods & Materials<br />

Sample Selection<br />

Acquiring an appropriate sample for back testing proved daunting. Initially we ran some preliminary back tests <strong>of</strong> our proposed %b indicator on a sample<br />

consisting <strong>of</strong> those stocks in the S&P 500 as <strong>of</strong> February 2007. This back test generated very impressive results from 1990 forward. In fact, the results seemed too<br />

good to be true. We realized that other analysts could justifiably criticize the backtest sample as suffering from survivor bias 4 and look-ahead bias. 5 Look-ahead<br />

bias results from using information in a backtest that was unknown during the period analyzed. Clearly, investors in 1990 had no way to know what stocks would<br />

constitute the S&P 500 in 2007. Survivor bias results when a study fails to account for stocks that have ceased trading due to mergers, acquisitions or bankruptcies.<br />

Survivor bias also results when for other reasons an index selection committee deletes and replaces a constituent.<br />

What we wanted for our sample was the full history <strong>of</strong> closing quotes for all stocks that were in the S&P 500 from 1990-2006 during the time those stocks were<br />

in the index, including the non-surviving stocks. We were unable to acquire that sample. Instead, we created a sample selection universe using the following protocol.<br />

Our sample contains end-<strong>of</strong>-day-prices for seventeen years, 1990-2006, on S&P 500 constituent stocks. From 1990-1997 we included only stocks that were on the<br />

January 1990 S&P 500 constituent list. From 1998-2006 we included prices for all stocks on the January 1998 constituent list. Starting in 2004 for the period 2004-<br />

2006, we added all prices for all stocks appearing on the January 2004 constituent list. For all spans and the full period, we included prices <strong>of</strong> non-surviving stocks<br />

up to the date that they ceased trading. Our sample contains 815 stocks, 490 <strong>of</strong> which were trading at year-end 2006.<br />

S<strong>of</strong>tware Tools and Data Services<br />

We downloaded constituent lists for the S&P 500 and prices for inactive, non-surviving stock from the Bloomberg Pr<strong>of</strong>essional Terminal. We downloaded<br />

surviving stock price histories from Yahoo Finance. We primarily used Amibroker 6 , a popular technical analysis and charting s<strong>of</strong>tware application, and the Amibroker<br />

Formula Language to design and test trading strategies and indicators. We used also Micros<strong>of</strong>t Excel for various purposes in our study.<br />

Variables, Trading Algorithm, Code<br />

We tested a system based on 65-trading-day (three months) %b against our sample selection universe.<br />

At the close <strong>of</strong> every trading day over the test period, our trading algorithm ranked all stocks from highest<br />

to lowest according to %b score. On the first trading day, January 2, 1990, the trading algorithm bought the<br />

40 lowest ranked stocks, investing 2.5% <strong>of</strong> portfolio equity in each stock. Once purchased, the algorithm<br />

held any given stock until it moved up and out <strong>of</strong> the ranks <strong>of</strong> the 80 lowest ranked stocks. At that point,<br />

the algorithm sold the stock and rotated the proceeds back into one <strong>of</strong> the 40 lowest ranked stocks not<br />

already held. The back test ended December 31, 2006. The algorithm recorded trade executions at the<br />

closing price the next day after order entry. The algorithm continued to execute this rotational trading<br />

every trading day <strong>of</strong> the 17-year back test period. At the time <strong>of</strong> purchase, the amount invested in any<br />

stock purchase could not exceed 2.5% <strong>of</strong> current portfolio equity but could be less if available cash was<br />

less than 2.5%. There was no rule forcing rebalancing <strong>of</strong> existing positions. The system traded long only,<br />

without margin, and stayed 100% invested. We named this strategy “%b BW” (Buy Weakness).<br />

Jo u r n a l <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> • 2008 • Issue 65<br />

Here is the code in Amibroker Formula Language:


Variable Initialization and Optimization<br />

Note that in the fourth line <strong>of</strong> the code we applied a filter. This filter removes stocks from purchase consideration and forces a sale if the stock price was under<br />

$1.00 and the date was after January 1, 1998. Although this filter actually reduced system total return, we used it anyway because when inspecting the trade logs we<br />

noticed that the system was initiating trades in low price stocks that were no longer in the S&P 500 (though they were at one time). Because our sample price data is<br />

split-adjusted, we avoided applying the filter to prices before 1998 since many stocks before that time traded at actual prices much higher than their sub $1.00 splitadjusted<br />

price would indicate and were in fact in the S&P 500.<br />

In order to reduce trade activity, we also required the algorithm to hold a stock at least four trading days before selling (SetOption(“holdminbars”, 4)). We chose<br />

65-day %b, 80-rank “worst rank held”, and 2.5% position size without rigid optimization for maximum total return or any other specific outcome. In our judgment,<br />

system performance was reasonably robust across a relevant range <strong>of</strong> optimization values.<br />

Our reported back test results assume a 0.1% cost per trade (0.2% round-trip). We noticed that very short (5-20 day) %b BW back tested impressively with a 0%<br />

assumed cost, but performance degraded dramatically when tested with a 0.1% cost per trade.<br />

We also tested our rule in reverse by changing the second to last line <strong>of</strong> the code from – PB to + PB. We named this strategy “%b BS” (Buy Strength) since it<br />

buys strong stocks with high relative %b. Recall that high %b means that a stock price is near or above its top Bollinger Band.<br />

Results<br />

Table 1 presents the results <strong>of</strong> our back tests on the custom sample described previously. The first column represents a buy and hold strategy on the S&P 500<br />

price index over the backtest period. The second column tests our proposed strategy, %b BW. The final column tests the %b BS Strategy.<br />

*A similar back test <strong>of</strong> %b BW on our initial biased sample (the current S&P 500 constituents) generated annualized total return <strong>of</strong> 31.6%; %b BS generated<br />

annualized total return <strong>of</strong> 3.2%. We provide this information as an example <strong>of</strong> the potential effects <strong>of</strong> sample bias on reported system performance. Also,<br />

note that the pronounced difference in total return between the two strategies appears to be relatively consistent regardless <strong>of</strong> the sample.<br />

*We calculate the alpha depicted in Figure 3 differently than the alpha reported in Table 1. The alpha in Figure 3 is a linear regression estimate modeled as Strategy Return = alpha + Beta (Return on the S&P 500). The alpha<br />

reported in Table 1 is the annualized mean difference <strong>of</strong> paired comparisons on 4287 observations <strong>of</strong> daily returns on the S&P 500 versus a unit <strong>of</strong> equity in the % BW strategy.<br />

Figure 4 plots a weekly comparative relative strength line 8 from 1990-2006 <strong>of</strong> the %b BW strategy using the S&P 500 Price Index as the base price. We delineate<br />

two major periods <strong>of</strong> relative underperformance.<br />

Figure 4.<br />

Tests <strong>of</strong> Statistical Significance<br />

Is the difference in return between the %b BW strategy and the S&P 500 statistically significant? To answer that question, we used a paired comparisons test <strong>of</strong><br />

4287 paired differences in daily returns from 1990-2006. The sample mean difference was .0533% per day (the mean daily alpha). The sample standard deviation <strong>of</strong><br />

the mean difference was .7462% (the daily tracking error). The standard error <strong>of</strong> the sample mean difference was .7462% * 4287^.5 = .0114%. The calculated test<br />

statistic was z = (.0533/.0115) = 4.68. The two-tailed P value is less than 0.0001. The difference in returns is extremely statistically significant.<br />

Is the risk-adjusted return <strong>of</strong> the %b trading strategy statistically significant? The Information Ratio 8 , also known as the appraisal ratio, is a widely used risk<br />

metric that measures risk and return relative to an appropriate benchmark. The information ratio equals alpha divided by tracking error. We tested to determine if the<br />

information ratio (IR) <strong>of</strong> the %b strategy was greater than zero:<br />

t – statistic = IR • T<br />

Where T is the number <strong>of</strong> years.<br />

From Table 1 we see the information ratio for the %b strategy equaled 1.15. So our test statistic is t = 1.15 * 17^.5 = 4.74 with df =16. The two-tailed P value<br />

equals 0.0003. The difference is extremely statistically significant.<br />

Discussion<br />

The evidence supports our thesis that a rotational trading algorithm using relative %b rankings can select stock portfolios that beat the risk-adjusted return on<br />

the S&P 500. Moreover, those portfolios consist only <strong>of</strong> S&P 500 constituent stocks. For perspective, a search <strong>of</strong> the expansive Morningstar mutual fund database<br />

in February 2007 reveals that just three mutual funds had an annualized rate <strong>of</strong> return in excess <strong>of</strong> 18% over the past fifteen years. None <strong>of</strong> those returns exceeded<br />

19%. The %b BW Strategy* returned 24.1% annualized with surprisingly little risk relative to the benchmark. The charts in Figures 3 and 4 as well as the Sharpe<br />

and Information Ratios reported in Table 1 provide the relevant risk assessment analytics.<br />

*The historical performance <strong>of</strong> a simulated trading strategy is not a guarantee <strong>of</strong> future returns.<br />

Admittedly, we have presented back test results that fly in the face <strong>of</strong> the well-worn trader’s axiom “Cut your losses short; let your pr<strong>of</strong>its run.” Table 2 confirms<br />

that the %b BW system <strong>of</strong>fers no protection against ruinous losses at the asset level. The diversification <strong>of</strong> an equal-weight 40 stock portfolio afford the only down<br />

side protection, a striking demonstration <strong>of</strong> the critical importance <strong>of</strong> position sizing and diversification in system development.<br />

While our results are statistically significant, the economic significance is less straightforward. The system trades frequently averaging over three trades per<br />

day. For taxable investors, returns would be taxed 100% as unfavorable short-term capital gains. From Table 1 we see the average pr<strong>of</strong>it per trade is 1.2% net <strong>of</strong> an<br />

assumed .2% round trip transaction costs. That is likely satisfactory only for a trader using an efficient broker9 and perhaps more importantly, trade size must be<br />

sufficiently small to have only a modest impact on market prices. Assessing potential slippage10 is clearly an important consideration when evaluating any system.<br />

Finally, the results suggest that investors overreact, possibly to news or changing prices, in a three-month (65- trading day) frame <strong>of</strong> reference. By design, our<br />

indicator look-back period corresponds with the three-month earnings report cycle for stocks as well as the performance reporting cycle for many asset managers<br />

capturing possible earnings-announcement and window dressing11 effects.<br />

Ichimoku Kinko Hyo<br />

Véronique Lashinski, CMT<br />

Goichi Hosoda, invented the cloud charts, or Ichimoku Kinko Hyo charts, in Japan before World War II. The method uses moving averages based on the middle<br />

<strong>of</strong> the range over a period <strong>of</strong> time, then shifts the lines, in the past and in the future.<br />

In this paper, we will compare hypothetical trading results in some US commodity futures markets, when using the base moving average crossover, with a few<br />

combinations <strong>of</strong> the different filters provided by the method.<br />

Outline Ichimoku Kinko Hyo on commodity futures<br />

I- Description/overview <strong>of</strong> the cloud lines, and basic trade signals derived from these lines.<br />

II- Tests.<br />

II-A Trade entry on Kijun Sen/Tanken Sen crossover, with no other condition. Exit on reverse Kijun Sen/Tenkan Sen crossover, with no other condition.<br />

II-B Trade entry on Kijun Sen/Tanken Sen crossover, adding both the Chikou Span and the cloud as filters. Exit when either condition no longer fulfilled.<br />

Conclusion: did the Chikou Span improve results?<br />

II-C Trade entry on Kijun Sen/Tanken Sen crossover, adding the market position relative to the cloud at the time <strong>of</strong> the signal as a filter. (above the cloud for buy,<br />

under the cloud for sell) Exit on reverse Kijun Sen/Tenkan Sen crossover, with no other condition.<br />

Conclusion: what is the impact <strong>of</strong> delaying the entry until the market position relative to the cloud confirms the outlook (above the cloud being bullish, and<br />

under the cloud, bearish)?<br />

Conclusion: does an aggressive entry, attempting to capture the move early make a difference?<br />

II-E Trade entry on Kijun Sen/Tanken Sen crossover, adding the Chikou Span as filter. (above the Chikou Span for buy, under the Chikou Span for sell) Exit on<br />

reverse Kijun Sen/Tenkan Sen crossover, with no other condition.<br />

I Description/Overview<br />

Description/Overview <strong>of</strong> the cloud lines, and basic trade signals derived from these lines.<br />

I-A Overview<br />

A newspaper writer, Goichi Hosoda, invented the cloud charts, or Ichimoku Kinko Hyo charts, in Japan before World War II. The various lines are built from the<br />

middle <strong>of</strong> the range over different periods, with some <strong>of</strong> the lines shifted in the future. One more line is made using the close, plot in the past.<br />

Two <strong>of</strong> the lines are projected forward. The cloud is formed by the space between those two lines. As it is drawn in the future, it provides a unique, visual idea <strong>of</strong><br />

support and resistance in the future, not available in other techniques.<br />

This paper focuses on the five basic lines <strong>of</strong> the cloud chart, which are readily available in many charting systems. Using back testing, the author compares<br />

hypothetical results <strong>of</strong> trading systems based on the basic crossover in the method, using various combinations <strong>of</strong> the five lines, as added trade entry and/or exit filters.<br />

Hosoda’s original definitions were based on a six-day working week in Japan when he developed the method (which included more than the cloud charts presented<br />

below). As the author has adapted the cloud charts to a five-day working week in daily use, all the tests are based on the five-day working week assumption, except the<br />

last one, which uses the six-day working week.<br />

II-B Definitions <strong>of</strong> the Lines and Interpretations<br />

Tenkan-Sen/Turning line: (Highest high + lowest low)/2, for the past seven trading days. (nine trading days, in the case <strong>of</strong> the six-day working week<br />

environment) In other words, this is the middle <strong>of</strong> the range, over the past week and a half.<br />

Kijun-Sen/Base line: (Highest high + lowest low)/2, for the past 22 trading days. (The period is changed to 26 trading days, in the case <strong>of</strong> the six-day working<br />

week environment.)<br />

This is the middle <strong>of</strong> the range, but this time over the past month.<br />

Crossovers between the Tenkan Sen and the Kijun Sen produce buy and sell signals, in a similar way as moving averages do in Western techniques. (see figure 1)<br />

Figure 1: Kijun Sen and Tenkan Sen crossovers on the Crude oil, May 2006 contract.<br />

Chikou Span/Lagging Span: Today’s close, plotted 22 trading days behind. (The period is changed to 26 trading days, when operating in a six-day working week<br />

environment.)<br />

The position <strong>of</strong> the Chikou Span relative to prices gives an idea <strong>of</strong> market strength: when the Chikou Span is above the market prices, it is an indication <strong>of</strong> market<br />

strength (and vice versa for weakness). In other terms, prices 22 (26) days ago are relevant, and represent current support/resistance. (see figure 2)<br />

Figure 2: Chikou Span on the Crude Oil, May 2006 contract. The point marked (1) on the chart<br />

shows a point where Chikou Span crosses prices.<br />

Senkou Span A: (Tenkan-Sen + Kijun-Sen)/2, plotted 22 trading days ahead. (The period is changed to 26 trading days, when assuming a six-day working week.)<br />

Senkou Span B - (Highest high + lowest low)/2, for the past 44 days, plotted 22 days ahead. (The period is changed to 56 trading days, plotted 26 days ahead,<br />

in the case <strong>of</strong> a six-day working week.)<br />

The area between Senkou Span A and Senkou Span B is colored and represents “the cloud.” (see figure 3) It represents key support (if the cloud sits below prices)<br />

or resistance (if the cloud sits above prices).<br />

Figure 3: Senkou Span A and B on the Crude Oil, May 2006 contract. The cloud is the colored<br />

area between both lines.<br />

The position <strong>of</strong> the market relative to the cloud confirms the trend: uptrend if prices are above the cloud, downtrend if they are below the cloud. Some <strong>of</strong> the cloud<br />

attributes further qualify the strength <strong>of</strong> support/resistance. For example, if the market is above a rising cloud, the current uptrend has a better chance to continue.<br />

(see figure 4)<br />

Figure 4: Crude oil, February 2008 contract. The rising cloud brought support to the market during the corrective<br />

decline. Note also the Kijun Sen/Tenkan Sen crossover marked (1).<br />

If the market is under a declining cloud, the current downtrend has a better chance to continue.<br />

A very thin area in the cloud is a point <strong>of</strong> vulnerability <strong>of</strong> the current trend: with both lines close to each other, only a small move will be needed for the market<br />

to cross the cloud. (see figure 5)<br />

Figure 5: Natural Gas, February 2008 contract. The points marked (1) are areas where the cloud is very thin.<br />

The position <strong>of</strong> the Kijun Sen/Tenkan Sen crossover (see figure 1) relative to the cloud is significant. For example, a bearish crossover is a weak signal if it<br />

happens above the cloud (i.e. above significant support), normal if it happens inside the cloud, and strong if it happens below the cloud (see figure 6). The latter can<br />

be interpreted as an attempt to capture resumptions <strong>of</strong> the major trend, after short-term counter-trend corrective moves (and vice versa for buy signals).<br />

Figure 6: Crude oil, February 2008 contract. The first Kijun Sen/Tenkan Sen crossover is above the cloud, which<br />

is a weak sell-signal. The second crossover is right on the upper cloud line, making it normal/strong.<br />

The method puts the emphasis on the middle <strong>of</strong> the range. We note that in corrections, the cloud is typically close to the classic Fibonacci retracements. (see figure 7)<br />

The main difference is that while the Fibonacci retracements are static, in particular the 50% retracement, which is the mid-point <strong>of</strong> the move, the cloud will vary as levels<br />

are dropped out <strong>of</strong> the calculation, and new ones added.<br />

Figure 7. The cloud and Fibonacci retracements. Nymex Natural Gas, September 2007: note how both the cloud<br />

and the 50% retracement stopped the correction.<br />

II - Tests<br />

Testing Methodology:<br />

We used US commodity futures contacts. The ending date for all tests was October 3, 2007. For all contracts, we used equalized continuations, going back 1,000<br />

days from October 3, 2007. The results are theoretical, as the impact <strong>of</strong> spreads is removed. This can be substantial in commodities. However, this was necessary to<br />

provide a sufficient number <strong>of</strong> trades for comparison purposes. For simplification, we used continuations based on trading activity. The rollover from one contract to<br />

the next is made at the time <strong>of</strong> higher tick activity in the next contract. The adjustment (which removes the spread) is the difference between the two contracts at the<br />

time <strong>of</strong> rollover. The tests assumed no slippage, and no transaction costs were included. (see table 1)<br />

Table 1: Total results<br />

Jo u r n a l <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> • 2008 • Issue 65 45


46<br />

Finally, due to a much larger tick value in Nymex Natural Gas, that commodity was removed <strong>of</strong> the final calculations, as Natural Gas had too much impact on<br />

the total outcome.<br />

II-A<br />

Trade entry on Kijun Sen/Tanken Sen crossover, with no other condition. Exit on reverse Kijun Sen/Tenkan Sen crossover, with no other condition: this signal<br />

is named “tk1” in this paper. (see figure 8)<br />

Figure 8: Tk1, Example on Copper futures. (The indicators below the price chart “tk_sht1” and “TK_Lg1” represent the total<br />

pr<strong>of</strong>it as a line, and the closed pr<strong>of</strong>it as a histogram, for respectively the short system and the long system.)<br />

The net pr<strong>of</strong>its are: $146,533 for the long and $-57,191 for the short. The total pr<strong>of</strong>it, $89,342 was the highest <strong>of</strong> the six cases studied. However, this is<br />

immediately mitigated by the fact the total loss on the short side is the second largest <strong>of</strong> the twelve cases studied, and this method also has the highest maximum<br />

drawdown, at $352,000. This illustrates that this method would benefit from filters, aiming to reduce risk and preserve capital.<br />

Not surprisingly, this method also has more than/or very close to (for one case) double the number <strong>of</strong> the trades as the other methods.<br />

II-B<br />

Trade entry on Kijun Sen/Tanken Sen crossover, adding both the Chikou Span and the cloud as filters. Exit when either condition no longer fulfilled. This signal<br />

is named “tk2” in this paper. (see figure 9)<br />

total pr<strong>of</strong>it (green) or loss (red) as a line, and the closed pr<strong>of</strong>it (green) or loss (red) as a histogram, for the short system.)<br />

What is the impact <strong>of</strong> waiting for both cloud and Chikou Span filter, and to exit trades aggressively on adverse conditions?<br />

This is the only method where filters were used on trade exit. The result is a clear decline in losses. Both the duration <strong>of</strong> losing trades and the amount <strong>of</strong> losses is<br />

reduced. Both the average loss and the maximum drawdown are the smallest among the methods tested in this study. This makes this method particularly attractive.<br />

The total pr<strong>of</strong>it is not the highest, but in light <strong>of</strong> the risk reduction and capital preservation is quite acceptable at $55,289 and compares to the highest pr<strong>of</strong>it in this<br />

test (see table 1), $89,342 and the lowest pr<strong>of</strong>it at $15,010.<br />

II-C<br />

Trade entry on Kijun Sen/Tanken Sen crossover, adding the position relative to the cloud as filter. (above the cloud for buy, under the cloud for sell) Exit on<br />

reverse Kijun Sen/Tenkan Sen crossover, with no other condition. This signal is named “tk 3” in this paper. (see figure 10)<br />

What is the impact <strong>of</strong> delaying the entry until the cloud confirms the outlook?<br />

Figure 10: Three examples <strong>of</strong> unfavorable long trades on tk3, on copper futures. The filter based on the close and not the<br />

position <strong>of</strong> the crossover relative to the cloud results in whipsaws on this kind <strong>of</strong> situation.<br />

(The indicators below the price chart “tk_sht3”and “tk_lgt3” represent the total pr<strong>of</strong>it (green) or loss (red) as a line, and the<br />

closed pr<strong>of</strong>it (green) or loss (red) as a histogram, for respectively the short system and the long system)<br />

We can think <strong>of</strong> this system as attempting to capture the resumption <strong>of</strong> established medium-term trends after the end <strong>of</strong> short-term counter-trend corrections.<br />

This method provides the second highest total net pr<strong>of</strong>it. This is coming from the highest average pr<strong>of</strong>it <strong>of</strong> all six methods, the second highest percentage <strong>of</strong><br />

winning trades. The number <strong>of</strong> trades is less than half the number <strong>of</strong> trades in the first test, “tk1”, which did not have use the cloud nor the Chikou Span as entry<br />

filter, and this reduction was quite beneficial.<br />

Despite the entry filter, the average trade duration is the second highest <strong>of</strong> all six methods. The average loss is also the second highest, which is impacting the<br />

overall results <strong>of</strong> this method substantially. A comparison with the second test, “tk2” immediately above, suggests that this method would strongly benefit from<br />

earlier exit <strong>of</strong> losing trades.<br />

Separately, the trade system used the position <strong>of</strong> the daily settlement relative to the cloud as the trade entry filter, not the position <strong>of</strong> the crossover relative to<br />

the cloud, which would have been a stronger filter. This was chosen for an easier calculation. While it may not seem like a substantial difference, figure 10 on the<br />

previous page illustrates that trades are entered in sideways markets, where the cloud is not at its best performance. When the cloud is thin, and the crossover occurs<br />

either inside or under the cloud, strength towards the close can result in a close above the cloud, and longs are entered. The resulting losses remain small, but without<br />

these, tk3 would have had higher total pr<strong>of</strong>its in this test.<br />

II-D<br />

Trade entry on Kijun Sen/Tanken Sen crossover, adding the position relative to the cloud as filter. (under the cloud for buy, above the cloud for sell) Exit on<br />

reverse Kijun Sen/Tenkan Sen crossover, with no other condition. This signal is named ”tk4” in this paper. (see figure 11)<br />

What is the impact <strong>of</strong> an aggressive entry, attempting to capture the move early in the trend?<br />

Jo u r n a l <strong>of</strong> <strong>Technical</strong> <strong>Analysis</strong> • 2008 • Issue 65 47


48<br />

Figure 11: Tk4, example on copper futures. Note how this allows capturing more <strong>of</strong> the decline, as the signal occurs much<br />

earlier. (The indicators below the price chart “tk_sht43” and “tk_lgt4” represent the total pr<strong>of</strong>it (green) or loss (red) as a line,<br />

and the closed pr<strong>of</strong>it (green) or loss (red) as a histogram, for respectively the short system and the long system.)<br />

This resulted in the lowest total net pr<strong>of</strong>it in this test (see table 1), with a low percentage <strong>of</strong> winners. However, closer examination reveals that this system ranked<br />

fifth -fairly low- for trade count, trade duration, average loss and maximum drawdown, and ranked in second for average pr<strong>of</strong>it, which are all potentially encouraging<br />

results.<br />

The Achilles heel <strong>of</strong> this system is that short-term corrections result in trade exits, but if the longer term trend is still up, the trade would not necessarily be reentered.<br />

(For example, if the market is no longer under the cloud, but has risen inside, or above the cloud for long positions, and vice versa for short positions.) A<br />

substantial part <strong>of</strong> the trend, the later part, when it is confirmed, is missed. Other re-entry conditions could be considered in a more complex system.<br />

II-E<br />

Trade entry on Kijun Sen/Tanken Sen crossover, adding the Chikou Span as filter. (Chikou Span above prices for buy, and under prices for sell). Exit on reverse<br />

Kijun Sen/Tenkan Sen crossover, with no other condition. This signal is named ”tk5” in this paper. (see figure 12)<br />

Figure 12: Tk5, example on Copper futures (The indicators below the price chart “tk_sht5” and “tk_lgt5” represent the total<br />

pr<strong>of</strong>it (green) or loss (red) as a line, and the closed pr<strong>of</strong>it (green) or loss (red) as a histogram, for respectively the short system<br />

and the long system)<br />

This method produced middle <strong>of</strong> the road results, and had average scores. Its weak points were the fairly low average pr<strong>of</strong>it and the high count.<br />

II- F<br />

Trade entry on Kijun Sen/Tanken Sen crossover, adding the Chikou Span as filter. (above the Chikou Span for buy, under the Chikou Span for sell) Exit on reverse Kijun<br />

Sen/Tenkan Sen crossover, with no other condition. (see figure 13)<br />

In this case, all lines are calculated with the original 6-day week assumption. This signal is named ”tk6” in this paper.<br />

In the sample used, was it beneficial to have adapted the periods to the shorter working week?<br />

This system can be immediately compared with the fifth test, “tk5”. The comparison is favorable to the switch to the shorter working week, five-days.<br />

Figure 13: Tk 6 on Copper futures (The indicators below the price chart “tk_sht6” and “tk_lgt6” represent the total pr<strong>of</strong>it<br />

(green) or loss (red) as a line, and the closed pr<strong>of</strong>it (green) or loss (red) as a histogram, for respectively the short system and<br />

the long system.)<br />

Worse, this system had the unwanted privilege <strong>of</strong> having the highest average loss, the lowest average pr<strong>of</strong>it, and the lowest percentage <strong>of</strong> winning trades <strong>of</strong> all<br />

systems in our sample.<br />

III - General Conslusion<br />

The cloud system is typically used as a visual method by the analyst, and has shown to be a worthwhile analytical tool. The author likes especially that the cloud<br />

method uses the entire range, as opposed to the market closing price, the default source on most typical Western indicators. As such, cloud charts are one way to<br />

diversify the data used. However, there are times when the cloud chart is <strong>of</strong> little use, other than highlighting the lack <strong>of</strong> medium-term trend. Indeed, this is a trend<br />

following system, and as such, like with a typical Western moving average crossover system, a medium-term trend needs to exist. In medium-term sideways markets,<br />

the analyst will immediately “see” that the cloud is a tangled mess <strong>of</strong> lines, and will switch to another method. This would need to be somehow replicated in trading<br />

systems.<br />

When considering building a trade system with this method, the author recommends testing with the addition <strong>of</strong> a trend indicator, like an ADX for example.<br />

Further, having tighter exit conditions (as in tk2) dramatically reduced the maximum drawdown for both longs and shorts, making it the best method in our sample,<br />

in terms <strong>of</strong> risk management and capital preservation, and the author strongly advocates that any further testing be made with tighter exit signals than the simple<br />

reverse Kijun Sen/Tenkan Sen crossover.<br />

Using Style Momentum to Generate Alpha working paper revised: April 2008<br />

Abstract<br />

Russell style indexes exhibit significant momentum, particularly after medium term out- and underperformance. The existence <strong>of</strong> this momentum produces a<br />

diversified, index-based low-cost means to exploit momentum by incorporating relative style index performance into tactical allocation strategies. Such style index<br />

momentum trading strategies have outperformed on both a raw and risk-adjusted return basis, with the long minus short portfolio generating an average 9.25%<br />

annual return over the 34-year period analyzed. Although the excess returns vary, they are robust through time and after controlling for potentially confounding<br />

effects. Additionally, the returns are not driven by any single style index and portfolio reconstruction is, on average, required every six months.<br />

Introduction<br />

Prior research has shown the ability <strong>of</strong> various momentum strategies to generate excess returns at the firm, industry, and country level, but little research has been<br />

done using investment style data at the index level. (Swinkels [2004] provides an informative survey <strong>of</strong> the momentum literature.) Our paper extends this literature<br />

by examining whether momentum extends to Russell style indexes. This contribution is meaningful because it provides a diversified, index-based low-cost trading<br />

strategy to exploit such momentum.<br />

At the firm level, Lewellen [2002] shows that stocks partitioned based on size and book-to-market ratio exhibit momentum as strong as that in individual stocks<br />

and industries. Also, Chen and De Bondt [2004] provide evidence <strong>of</strong> style momentum within the S&P-500 index by constructing portfolios based on style criteria.<br />

However, constructing such portfolios can be costly, significantly eroding returns. Our focus is on indexes easily represented by exchanged traded funds, thereby<br />

producing a significant cost advantage and providing a low expense, diversified means to exploit style momentum by incorporating relative style index performance<br />

into tactical allocation strategies.<br />

Using Russell Large-Cap and Small-Cap style index data, Arshanapalli, Switzer, and Panju [2007] develop a market timing strategy using a multinomial timing<br />

model based on macroeconomic and fundamental public information. While their multinomial model does include prior market return variables to time their style<br />

index allocation decisions, their paper is significantly different from ours in several ways. First, they do not focus on the importance on style index momentum, nor<br />

do they discuss the significance <strong>of</strong> the prior market return variables in their model. Secondly, the beauty <strong>of</strong> our market-timing strategy is its simplicity. Only the<br />

raw, prior return <strong>of</strong> the Russell style indexes is required to make the asset allocation decision. In contrast, Arshanapalli, Switzer, and Panju [2007] require variables<br />

such as the Change in the Conference Board Consumer Confidence Index, U.S. Bond Default Premium, U.S. Bond Horizon Premium, S&P 500 Earnings Yield Gap,<br />

Change in the Consumer Price Index, etc. to construct their model. Further, their model requires generating conditional probabilities using a multinomial logit and the<br />

assigning <strong>of</strong> arbitrary cut<strong>of</strong>f probabilities when constructing trading rules. Additionally, Arshanapalli, Switzer, and Panju [2007] do not analyze short or long minus<br />

short portfolios, nor do they consider Russell Mid-Cap Value/Growth portfolios. Lastly, the vast majority <strong>of</strong> their analysis covers a shorter time period, 1979-2000<br />

versus 1972-2005, which fails to include the two most severe, post-War World II market declines, specifically the 1973-1974 and 2000-2002 crashes. The inclusion<br />

<strong>of</strong> those time periods further verifies the robustness <strong>of</strong> our analysis.<br />

We are also motivated to test the existence <strong>of</strong> style index momentum due to the proliferation <strong>of</strong> style index benchmarks. Both Lipper and Morningstar use style<br />

benchmarks to rate mutual fund performance. Our decision to focus specifically on Russell style indexes was influenced by their popularity, as <strong>of</strong> 2006, 54.5% <strong>of</strong><br />

institutionally managed U.S. equity funds (over $3.8 trillion in assets) were benchmarked against Russell indexes. 1<br />

Furthermore, Barberis and Shleifer [2003] provide a theoretical basis for our analysis. They model an economy with fundamental traders and positive feedback<br />

traders that chase relative style returns. The results being that “[p]rices deviate substantially from fundamental values as styles become popular or unpopular” (p.<br />

190). Our results, using Russell style index data, provide additional support for their model.<br />

Style Index Data and Portfolio Structure<br />

Using monthly data from January 1969 to December 2005, we examine momentum across a broad range <strong>of</strong> economic and market conditions. For the years 1969<br />

to 1996 we use the constructed style index data from Chan, Karceski, and Lakonishok [2000]. 2 For years 1997 to 2005 we use the actual Russell index data. Indexes<br />

are the Russell 2000 Growth (Value) for Small-Cap Growth (Value), the Russell Mid-Cap Growth (Value) for Mid-Cap Growth (Value), and the Russell Top 200<br />

Growth (Value) for Large-Cap Growth (Value). For the remainder <strong>of</strong> this paper these portfolios will be denoted by SG, SV, MG, MV, LG, and LV, respectively. Note,<br />

in total the data covers 37 years, but the results cover a 34 year period due to our analysis <strong>of</strong> 36 month formation period performance.<br />

To view the extent to which momentum may exist, we analyze various formation periods to rank each <strong>of</strong> the six indexes based on their return over that period<br />

<strong>of</strong> time. For each index held we then calculated subsequent returns for various holding periods. An example would be a 24,6 portfolio, which means we ranked the<br />

style indexes based on 24 month prior performance, then held each single style index portfolio 3 for six months based on its formation period performance. After the<br />

style index is held for six months, indexes are re-ranked on prior 24 month performance then a single index is again selected and held for another six months with<br />

the process continuing for the time period covered. The top (bottom) ranked portfolio would consist <strong>of</strong> the style indexes selected, and held in six month increments,<br />

through time based on the highest (lowest) performance in the 24 month formation period.<br />

Pr<strong>of</strong>itability <strong>of</strong> Various Style Index Momentum Strategies<br />

To analyze the performance <strong>of</strong> style index momentum based trading strategies, we rank the style indexes based on formation period performance, then buy the<br />

top performing index and short the bottom performing index. The long top minus short bottom (Long-Short) position is then held for the designated holding period.<br />

Exhibit 1 reports the average monthly returns to Long-Short portfolios across various portfolio formation and holding periods.<br />

Results are generally positive and statistically significant, especially for the shorter holding periods. Long-Short returns across various formation periods peak at<br />

12 months <strong>of</strong> prior performance. Across various holding periods the Long-Short returns peak at 1 month. Therefore, top performing Long-Short portfolio was 12,1<br />

with an average monthly return <strong>of</strong> 0.85% (p-value < 1%). Based on these results, the remainder <strong>of</strong> the paper focuses on portfolios composed <strong>of</strong> one style index with<br />

a 12 month formation and one month holding period. While this 12,1 portfolio was the highest performer for the 34 year period, when various time periods were<br />

analyzed it was not always the top performer 4 . However, the top performing strategy was consistently driven by medium-term momentum with prior performance in<br />

the 8 to 14 month range.<br />

Exhibit 2 shows the monthly level and persistence <strong>of</strong> the return outperformance and underperformance for the six portfolios selected based on the ranking <strong>of</strong> their<br />

prior 12 month performance relative to the average <strong>of</strong> the six Russell indexes. The average monthly return is presented for each <strong>of</strong> the 12 months <strong>of</strong> the formation<br />

period and for 36 months after each style index is ranked. For the top and bottom ranked portfolios the average cumulative 12 month prior return was 28.10% and<br />

1.12%, respectively. For the first month <strong>of</strong> the holding period the average return for the top and bottom portfolios was 1.57% and 0.68%, respectively.<br />

All portfolios revert back to the mean, but the portfolio with greatest (lowest) prior 12 month relative performance exhibits the greatest outperformance<br />

(underperformance) persistence. This persistence is particularly pronounced for the top style index ranked by 12 month formation period performance, which<br />

continues to outperform all other portfolios for 14 months. Also, the top and bottom ranked portfolios have the greatest spread between portfolio performance and<br />

the average index return in the first month <strong>of</strong> the holding period, which is consistent with the results in Exhibit 1.<br />

Performance <strong>of</strong> 12,1 Style Index Momentum Portfolios<br />

Exhibit 3 reports the annualized results for six 12,1 portfolios, Long-Short 12,1 portfolio, the six Russell indexes used to build those portfolios, and other indexes<br />

for comparison. As predicted by style index momentum, the 12,1 portfolio performance increases monotonically with prior 12 month performance. The Long-Short<br />

12,1 portfolio has an annualized return <strong>of</strong> 9.25% and a Beta estimate <strong>of</strong> -0.01. The top 12,1 also outperforms all <strong>of</strong> the Russell style indexes and other indexes on<br />

return, Sharpe ratio, Treynor ratio, and Jensen’s alpha.<br />

More importantly, on a risk-adjusted basis the six ranked 12,1 portfolios improve monotonically with prior 12 month performance. The Sharpe ratio, Treynor<br />

ratio, and Jensen’s alpha all show such improvement, indicating that style index momentum not only provides excess raw returns, but excess returns on a riskadjusted<br />

basis as well.<br />

Using Fama-French 3-factor models we further analyze the top, bottom, and Long-Short 12,1 portfolio returns over the 34 year period 5 . Exhibit 4 reports a<br />

monthly alpha <strong>of</strong> 0.53% (6.60% annualized) for the top 12,1 portfolio and -0.41% (-4.81% annualized) for the bottom 12,1 portfolio, both statistically significant<br />

with p-values < 1%. The Long-Short portfolio produced a monthly alpha <strong>of</strong> 0.45% (5.56% annualized) which was statistically significant at the 5% level. These<br />

results again provide evidence <strong>of</strong> momentum in style indexes even after controlling for market, size, and book-to-market factors.<br />

Allocation and Average Return <strong>of</strong> Selected Style Indexes<br />

Each <strong>of</strong> the six 12,1 portfolios’ allocation (Panel A) and contribution to returns (Panel B) <strong>of</strong> the six Russell indexes are reported in Exhibit 5. For the top<br />

performing portfolio, and for all 12,1 portfolios, the largest allocation was the SV at 34.1%. This means that SV had the largest prior 12 month performance 34.1%<br />

<strong>of</strong> the time and was therefore held in the 12,1 portfolio 34.1% <strong>of</strong> the 34 year period analyzed. The SV was also the highest performing style index over the 34 year<br />

period analyzed, but was not the leading average return contributor to the 12,1 portfolio performance. The largest contributor was MG, followed by SG, LV, then SV,<br />

with average monthly returns <strong>of</strong> 2.11%, 1.97%, 1.78%, and 1.69%, respectively. This indicates that the momentum exhibited is not simply a SV phenomenon. For<br />

the bottom performing 12,1 portfolio the largest allocation was the LG at 32.8% and the smallest was the MV at 3.7% with average monthly returns <strong>of</strong> 0.11% and<br />

0.70%, respectively.<br />

Persistence Through Time <strong>of</strong> 12,1 Portfolios<br />

To succinctly show that the 34 year period results are not solely driven by a particular time period and are robust through time we report the top, bottom, and<br />

Long-Short 12,1 portfolios in Exhibit 6 (on page 54). Top is the 12,1 portfolio with the highest formation period performance, bottom is the 12,1 portfolio with the<br />

lowest formation period performance, and Long-Short is the difference. On an annualized return basis the returns for the periods analyzed vary from 3.08% to<br />

13.71%, depending on the period analyzed, and averaged 9.25%. If you exclude the two largest return periods from ’72 to ’80 the Long-Short portfolio still returns<br />

an annualized 5.08%. On an individual calendar year basis, not reported for brevity, the worst Long-Short portfolio return was -20.35% in 2000 and the best was<br />

50.11% in 1999.<br />

Average Holding Period<br />

To further evaluate the momentum persistence we analyzed the average holding periods <strong>of</strong> the top and bottom 12,1 portfolios. Even though style indexes were<br />

analyzed on a monthly basis for reshuffling, on average, reshuffling was only required about twice a year. The top and bottom positions are held for an average <strong>of</strong><br />

5.65 and 6.10 months, respectively. Interestingly, the LG had the longest holding period for both the top and bottom position. The bottom position was for 26 months<br />

from March 1976 to April 1978 and the top position was for 24 months from May 1989 to April 1991. The relatively infrequent need for rebalancing when combined<br />

with the low cost <strong>of</strong> exchange traded funds supports the viability <strong>of</strong> this momentum trading strategy.<br />

Conclusion<br />

Style index momentum is particularly interesting since it provides a diversified, low-cost trading strategy to exploit it. This inexpensive and diversified option<br />

provides the opportunity for money managers, regardless <strong>of</strong> the amount <strong>of</strong> assets under management, to include such strategy into their tactical asset allocation<br />

decisions. Such style index momentum trading strategies have outperformed on both a raw and risk-adjusted return basis, with the long minus short portfolio<br />

generating an average 9.25% annual return over the 34-year period analyzed. Although the excess returns vary, they are robust through time and after controlling for<br />

potentially confounding effects.<br />

Panic<br />

Panics in the commercial and financial world have been compared to comets in the astronomical world. It has been said <strong>of</strong> comets that they have no regularity <strong>of</strong><br />

movement, no cycles, and that their movements are beyond the domain <strong>of</strong> astronomical science to find out. However, the writer claims that Commercial Revulsions<br />

in this country, which are attended with financial panics, can be predicted with much certainty; and the prediction in this book, <strong>of</strong> a commercial revolution and<br />

financial crisis in 1891 is based upon the inevitable cycle which is ever true to the laws <strong>of</strong> trade, as affected and ruled by the operations <strong>of</strong> the laws <strong>of</strong> natural<br />

causes.<br />

The panic <strong>of</strong> 1873 was a commercial revolution; our paper money was not based upon specie, and banks only suspended currency payments for a time in this crisis.<br />

As it is not in the nature <strong>of</strong> things in succeeding cycles to operate in the same manner, the writer claims that the “signs <strong>of</strong> the times” indicate that the coming<br />

predicted disturbance in the business world will be not only an agricultural, manufacturing, mining, trading, and industrial revulsion, but also a financial catastrophe,<br />

producing a universal suspension <strong>of</strong> payments and bank closures.<br />

It is not necessary to give a detailed account <strong>of</strong> the effects <strong>of</strong> disorderly banking in our colonial and revolutionary history, and the different panics prior to the<br />

war <strong>of</strong> 1812, to establish cycles in commerce and finance.<br />

Such a history would fill many pages without answering the purpose <strong>of</strong> this book, and would be as intricate and difficult to understand as the prices <strong>of</strong> stocks and<br />

gold in Wall Street.<br />

1 [Editor Note … Benner’s use <strong>of</strong> the word depression means bear market trend or economic contraction. The 1819 bank collapse from the cost <strong>of</strong> war, excess currency in circulation, and money moving<br />

out <strong>of</strong> the country is well defined. Benner’s economic forecast for a recession in 1891, though written in 1884, is only <strong>of</strong>f a year. The true brilliance is Benner’s cyclical analysis work throughout this book.<br />

Benner’s book was first published in 1875 and is widely viewed as the first market analysis book written in North America. This excerpt begins on page 96 after a detailed study <strong>of</strong> high to low price cycles<br />

in Steel, Hogs, Corn, and Cotton. Long term cycle analysts <strong>of</strong> today’s markets will find Benner provides annual market data from 1821 in this book.]


The war <strong>of</strong> 1812 was the period in history <strong>of</strong> the United States <strong>of</strong> America when it was deemed a necessity for this country a manufacturing nation, as a balance<br />

wheel, to maintain the prosperity <strong>of</strong> agriculture and commerce, and also to declare her independence forever from any nation upon the earth.<br />

It is a doleful commentary upon the times that such calamities in the history <strong>of</strong> our country, as hereafter mentioned, should have occurred amidst a pr<strong>of</strong>usion <strong>of</strong><br />

all the elements <strong>of</strong> wealth, prosperity in trades and manufactures, and independence in the arts and sciences.<br />

It will only be necessary for the purposes <strong>of</strong> this book to state that the business <strong>of</strong> this country before, during, and after the war <strong>of</strong> 1812 had culminated in the<br />

year 1819, as commercial history will show; and that a reaction in business followed this year, the beginning year in our cycles <strong>of</strong> commerce and panic.<br />

However, we deem it important to notice at this period the operations <strong>of</strong> banking in brief as a good criterion <strong>of</strong> the prosperity or adversity in general business,<br />

and the fluctuations in the activity <strong>of</strong> industry and commerce.<br />

In the Report <strong>of</strong> Finances for 1854 and 1855, it is stated that the adoption <strong>of</strong> the Federal Constitution in 1787 to the year 1798, no people enjoyed more happiness<br />

or prosperity than the people <strong>of</strong> the United States, nor did any country ever flourish more within that space <strong>of</strong> time. During all this time, and up to the year 1800,<br />

coin constituted the bulk <strong>of</strong> the circulation; after this year the banks came, and all things became changed, like the Upas tree, they have withered and impaired the<br />

healthful condition <strong>of</strong> the country, destroyed the credit and confidence which men had in one another.<br />

The bank-note circulation began to exceed the total specie in the country in the years 1815, ’16, and ’17, and in the year 1818, the bank mania had reached its<br />

height; more than two hundred new banks were projected in various parts <strong>of</strong> the Union. The united issues <strong>of</strong> the United States Bank, and <strong>of</strong> the local banks, drove<br />

specie from the country in large quantities, and in the year 1819, when the culmination in general business had been reached, and contraction <strong>of</strong> the currency began<br />

to be felt, multitudes <strong>of</strong> banks and individuals were broken. The panic producing a disastrous revulsion in trade, caused the failure <strong>of</strong> nine-tenths <strong>of</strong> all the merchants<br />

in this country and others engaged in business, and spread ruin far and wide over the land.<br />

Two-thirds <strong>of</strong> the real estate passed from the hands <strong>of</strong> the owners to their creditors.<br />

A banker, in a letter to the Secretary <strong>of</strong> State, in 1830, describes the times as follows;<br />

“The disasters <strong>of</strong> 1819 which seriously affected the circumstances, property, and industry <strong>of</strong> every district <strong>of</strong> the United States will be long recollected.<br />

A sudden and pressing scarcity <strong>of</strong> money prevailed in the spring <strong>of</strong> 1822; numerous and very extensive failures took place in 1825; there was great<br />

revulsion among the banks and other monied institutions in 1826. The scarcity <strong>of</strong> money among the trades in 1827 was disastrous and alarming; 1828 was<br />

characterized by failures among the manufactures and trades in all branches <strong>of</strong> business.”<br />

After the year 1828 business continued to be depressed, vibrating according to circumstances until 1834, a year <strong>of</strong> extreme dullness in all branches <strong>of</strong> trade;<br />

after which our stock <strong>of</strong> precious metals increased very fast, business revised, and in the year 1835 and ’36, the imports <strong>of</strong> gold and silver increased to an enormous<br />

extent; as the banks increased their reserves <strong>of</strong> species, they also correspondingly issued bank notes – each increased issue <strong>of</strong> paper money led to the establishment<br />

<strong>of</strong> new banks.<br />

The State banks that had numbered in 1830 only three hundred and twenty-nine, with a capital <strong>of</strong> one hundred and ten millions, increased, according to the<br />

treasury report, by the first <strong>of</strong> January, 1837, to six hundred and twenty-four, or, including branches, to seven hundred and eighty-eight, with a capital paid in <strong>of</strong> two<br />

hundred and ninety millions.<br />

Mark the result and culmination; a panic! In the month <strong>of</strong> May, 1837, a suspension <strong>of</strong> specie payments by all the banks, and a general commercial revulsion<br />

throughout the country, involving the fortunes <strong>of</strong> merchants, manufacturers, and all classes engaged in trade, in consequence <strong>of</strong> a ruinous fall in prices. This year <strong>of</strong><br />

reaction makes the second year in our panic cycles, and is eighteen years from 1819.<br />

It is not necessary to go over almost the same history again to show that business was depressed, and trade was stagnant after 1837 down to the year 1843, and then<br />

up and down to the year 1850, a year <strong>of</strong> extreme dullness in all branches <strong>of</strong> trade and industry, after which year a change came, and business was again prosperous to the<br />

year 1857, when we again experienced a commercial and financial crisis and reaction, not only in this country but all over the world, making the third year in our cycles,<br />

and twenty years from 1837.<br />

History repeats itself with marvelous accuracy in detail from one panic year to another. The general direction <strong>of</strong> business after the panic <strong>of</strong> 1857 was on the same<br />

downward grade that had characterized the times after the panic <strong>of</strong> 1819 and 1837, until all business had culminated in depression in the year 1861, after which trade<br />

again improved, and was very active during the war <strong>of</strong> the rebellion and up to the year 1865, when a temporary reaction set in. Reader let me observe here, that if then<br />

had been the time for a commercial revulsion and panic in money, the catastrophe would have been the most deplorable national calamity upon record. However, the<br />

cycle was not then complete. And the commerce and trade <strong>of</strong> the country continued to be semi-prosperous until 1870, after which year commercial activity was the<br />

order <strong>of</strong> the day, all branches <strong>of</strong> business and manufacture flourished and was prosperous; our railroad building was astonishing in the world in the years 1871, ’72;<br />

but the end must come, and in September 1873, we had the culmination – a crashing panic, and reaction in all trades, manufactures, railroads, and industries, which<br />

is still going on, and we have not reached hard pan.<br />

These are facts <strong>of</strong> late history, and are so fresh in the recollection <strong>of</strong> the mind <strong>of</strong> the reader, that it is only necessary to refer to them. The panic <strong>of</strong> 1873 makes<br />

the fourth year in our panic cycles, and sixteen years from 1857.<br />

As to whether it is the paper money or the manufacturing and trading industries <strong>of</strong> the country, which call out and into use the paper money that produce these<br />

periodical inflations and contractions, by which trade is stimulated and deranged, and extremes in business activity is brought about, is a matter for the statesman and<br />

historian to ascertain and record; [ ed note – the first book written was by a technical analyst and not a fundamentalist.] it is only sufficient for our purposes to point<br />

out the years, and to show that the preceding years were prosperous and pr<strong>of</strong>itable years in trade; while the succeeding years, for a certain length <strong>of</strong> time, were years<br />

<strong>of</strong> depression and loss in business; and we observe that since the business <strong>of</strong> the country has abandoned specie (ed note, gold and silver) as a currency, and adopted<br />

paper money in lieu there<strong>of</strong>, the manufacturing interests have attained larger proportions, and that there are more regularity and system in the return <strong>of</strong> the advance and<br />

decline in general business, and that the culminating years in activity and depression can be calculated and ascertained with greater certainty.<br />

The panics <strong>of</strong> 1819, ’37, ’57, and ’73, during this period <strong>of</strong> years, stand out upon the pages <strong>of</strong> history <strong>of</strong> this country in their magnitude compared with other<br />

panics. (ed. Text removed.)<br />

Commencing with the commercial revulsion <strong>of</strong> 1819, we find it was eighteen years to the crisis <strong>of</strong> 1837, twenty years to the crisis <strong>of</strong> 1857; and sixteen years<br />

to the crisis <strong>of</strong> 1873 – making the order <strong>of</strong> cycles sixteen, eighteen, and twenty years and repeat. The cycle <strong>of</strong> twenty years was completed in 1857, and the cycle<br />

<strong>of</strong> sixteen years ending in 1873, was the commencement <strong>of</strong> the repetition <strong>of</strong> the same order. It takes panics fifty-four years in their order to make a revolution, or to<br />

return in the same order; the present cycle consisting <strong>of</strong> eighteen years will end in 1891, when the next panic will burst upon us with all its train <strong>of</strong> woes. 2<br />
