performance… for instance there was one trader with a very big drawdown, but it was eight years ago.<br />

So we went around and talked to these people: “Tell me about that 37-percent drawdown you had in<br />

2003, what was that all about.”<br />

Going through this process, we wound up with a group of ten or so traders that was just a great group.<br />

And what is remarkable about this group is how they actually do as a portfolio once you take a look at<br />

composite performance: “What would have happened had I given these people funding five, six, seven<br />

years ago.”<br />

I know that past performance is no indication of future returns, but you have to go on something. You<br />

can’t just pick straws or throw a dart. The reality is that past performance is an indication of how a<br />

trader trades. It doesn’t indicate that a trader is going to repeat and repeat, but it’s the best thing you<br />

have to go on.<br />

JACK SPARROW: Were there any measures you particularly relied on?<br />

PETER BRANDT: Generally speaking we took a look at something called the Calmar Ratio, which is<br />

an acronym for “California Managed Accounts Reports.” The Calmar Ratio divides average annual<br />

rate of return for 36 months by maximum drawdown over 36 months, recalculated on a monthly basis.<br />

We made some modifications to the Calmar Ratio in our analysis of traders.<br />

The traders we liked had Calmar Ratios from 1.5 to 3.0, meaning that, at a ratio of 2.0, an average<br />

rate of return was double a worst drawdown.<br />

JACK SPARROW: So just to put that in layman’s terms: If you have a Calmar Ratio of 2.0, and an<br />

average annual return of 20%, that means your worst drawdown would have been 10%.<br />

PETER BRANDT: That is correct. And the traders were all in that range, but when we blended them<br />

together something interesting happened. We didn’t try to negatively correlate performance, and total<br />

performance was a straightforward calculation. There was no change in the composite returns of the<br />

group. But the BIG change was in composite drawdowns and magnitude of drawdowns. Those<br />

changed dramatically, where all of a sudden the worst drawdowns of the group as a combined<br />

portfolio dropped into the 2 to 3 percent range – and in 2010 there were no drawdowns at all, when<br />

measured on a month to month basis.<br />

JACK SPARROW: And that is because the traders in the group were so good, someone was always<br />

performing. When one was temporarily behind, another was always stepping up.<br />

PETER BRANDT: Exactly. They had their drawdowns at different points in time. So while the net<br />

returns were still there, the average drawdowns leveled off. And not only that, but the composite<br />

length of peak-to-valley-to-new-peak drawdowns shortened dramatically. While the average for each<br />

individual trader was around ten months for peak-to-valley-to-new-peak – ranging from six months to<br />

27 months – the longest drawdown for the group as a portfolio was only three months.<br />

I think a focus on risk-adjusted performance is a different way, an exciting way, of looking at<br />

combinations of traders. It is a concept that has great merit for institutions and large investors. As<br />

mentioned earlier, most people in managed futures have mainly looked at the performance side, not<br />

the risk side or the drawdown side.<br />

For me, the bottom line of it all is not about identifying traders who have had stellar returns. The<br />

bottom line is about finding traders who have managed their capital well, and have not gotten whipped<br />

too bad when things have been rough.<br />

JACK SPARROW: And of course, having both (stellar returns and excellent risk management) isn’t a<br />

problem either!<br />
