My ex gf started a hedge fund. Nobody would give her money for the longest time. She made 500k from 100k by trading options. With that said, in 2009 she put half mil of her own money in put options, betting it all on s&p to go lower. Well it did eventually, but not before she sold the options for a 95% loss of her principal a few weeks before expiration. She also buys $100s of dollars in lotto tickets every week. And she is a kleptomaniac. Ex gf for a reason. Anyway, the point I'm trying to make is that there are good and bad performers, male and female, and women have it tougher in the industry than men. It's easier to manage 50 million than 5 billion, and that is partly why women seem to do better in this study.
1) Women want to marry male hedgies, not become a hedgie. 2) Women want to perform "on" male hedgies, not male retail store cashiers.
I wish I could get women to be less risk-averse. Those who are willing to take a chance or two are good traders. We do not have to be right. We have the stuff to trade "what is." Less ego, more reality.
Most women I know have bigger egos than men. More reality? Women are some of the most deluded creatures on this planet. I don't mean to generalize, but some people would agree with me.
