Das kleine Buch der Market Wizards

The worse the fills are, the better your trade.

Second, I study the correlation of my trades to reduce my exposure. We do a daily computer analysis to see how correlated our positions are. Through bitter experience, I have learned that a mistake in position correlation is the root of some of the most serious problems in trading. If you have eight highly correlated positions, then you are really trading one position that is eight times as large.

It doesn’t feel like work, except when you lose—then it feels like work [he laughs]. For me, market analysis is like a tremendous multidimensional chess board. The pleasure of it is purely intellectual. For example, it is trying to figure out the problems the finance minister of New Zealand faces and how he may try to solve them. A lot of people will think that sounds ridiculously exotic. But to me, it isn’t exotic at all. Here is a guy running this tiny country and he has a real set of problems. He has to figure how to cope with Australia, the U.S., and the labor unions that are driving him crazy. My job is to do the puzzle with him and figure out what he is going to decide, and what the consequences of his actions will be that he or the market doesn’t anticipate. That to me, in itself, is tremendous fun.
