Find a Trading Method That Fits Your Personality

Traders must find a methodology that fits their own beliefs and talents. A sound methodology that is very successful for one trader can be a poor fit and a losing strategy for another trader. Colm O’Shea, one of the global macro managers I interviewed, lucidly expressed this concept in answer to the question of whether trading skill could be taught:

If I try to teach you what I do, you will fail because you are not me. If you hang around me, you will observe what I do, and you may pick up some good habits. But there are a lot of things you will want to do differently. A good friend of mine, who sat next to me for several years, is now managing lots of money at another hedge fund and doing very well. But he is not the same as me. What he learned was not to become me. He became something else. He became him.

Trade Within Your Comfort Zone

If a position is too large, the trader will be prone to exit good trades on inconsequential corrections because fear will dominate the decision process. Steve Clark, an event driven manager, advises, you have to “trade within your emotional capacity.” Similarly, Joe Vidich, a long/short equity manager warns, “Limit your size in any position so that fear does not become the prevailing instinct guiding your judgment.”

In this sense, a smaller net exposure may actually yield better returns, even if the market ultimately moves in the favorable direction. For example, Martin Taylor, an emerging markets equities manager, came into 2008 with a very large net long exposure in high beta stocks in an increasingly risky market. Uncomfortable with the level of his exposure, Taylor sharply reduced his positions in early January. When the market subsequently plunged later in the month, he was well positioned to increase his long exposure.

Had Taylor remained heavily net long, he might instead have been forced to sell into the market weakness to reduce risk, thereby missing out in fully participating in the subsequent rebound.  (more…)
