THE BASIS IN FUTURES ANALYSIS<br />

Although there is a direct connection between the basis <strong>and</strong> futures price, the basis<br />

does <strong>in</strong>fluence the price to some extent, especially when approach<strong>in</strong>g the maturity<br />

of the futures contract. Remember<strong>in</strong>g the formula<br />

(Cash price) � basis � (futures price) � (conversion factor)<br />

basis theory states that at the maturity date the basis (or error) has to be exactly zero<br />

for the CTD. The CTD is the physical commodity that will be delivered to holders<br />

of the futures contract if they have not chosen a cash delivery or reversed their hold<strong>in</strong>gs<br />

or rolled forward to the next contract delivery month.<br />

Dur<strong>in</strong>g the life of the future, the basis may fluctuate violently. Some analysts prefer<br />

to look at the price action of the CTD throughout the life of the futures. However,<br />

<strong>in</strong> cases where it is difficult to forecast the CTD accurately, that is where more than<br />

one <strong>in</strong>strument could be delivered on the futures Maturity Date, the behaviour of the<br />

basis is critical. Not all markets have the clearly identified CTD, as was the case <strong>in</strong><br />

the MATIF NNN throughout the 1990s, where although there were three or more<br />

<strong>in</strong>struments with<strong>in</strong> the basket of deliverables, only one had a clear advantage as the<br />

basis of the CDT was less than 10 while the others were greater than 30 for the life<br />

of the <strong>in</strong>strument, year after year. This made the NNN an <strong>in</strong>terest<strong>in</strong>g if simpler<br />

<strong>in</strong>strument to analyse. Dur<strong>in</strong>g that period, the UK Long Gilt futures with all its<br />

peculiarities may have had underly<strong>in</strong>g Gilts, which had a small basis but may not<br />

have been deliverable due to XD issues.<br />

Chart<strong>in</strong>g of the basis was simple for most of the life of the futures, but when<br />

approach<strong>in</strong>g maturity all potential deliverables had to have their associated basis<br />

charted as it was often difficult to forecast which <strong>in</strong>strument was go<strong>in</strong>g to be delivered.<br />

The difficulty arises when <strong>in</strong> the last few days of life, traders see that there is<br />

a strong argument for one particular basket member to be delivered. Anticipat<strong>in</strong>g a<br />

strong dem<strong>and</strong> for this on the day of maturity, a trader may buy this <strong>in</strong>strument <strong>in</strong><br />

the hope of the price ris<strong>in</strong>g significantly, as it is needed to fulfil delivery obligations<br />

on maturity day. This dem<strong>and</strong> for the physical asset will have an effect on the price<br />

of it (it will go up) <strong>and</strong> thus the basis relative to the futures contract will change.<br />

Indeed, <strong>in</strong> cases where there are several c<strong>and</strong>idates for potential delivery, buy<strong>in</strong>g<br />

one could have the effect of mak<strong>in</strong>g it no longer likely to be delivered. This is a difficult<br />

situation to be <strong>in</strong> for, if purchased but not required for delivery, the price may<br />

not go up as dem<strong>and</strong> is very low relative to the actual asset that is be<strong>in</strong>g delivered.<br />

Data issues are part <strong>and</strong> parcel of the daily gr<strong>in</strong>d for the technical analyst. Intraday<br />

technical analysts are particularly open to be<strong>in</strong>g hit with <strong>in</strong>correct prices, spikes<br />

or <strong>in</strong>deed dull hours. Data providers have improved their methods for catch<strong>in</strong>g such
