I actually agree with you. I believe that if 50 males and 50 females were trained to the same level of trading ability and skill, women would outperform men for the reasons you stated. It would coincide with statistics relating to men being more willing to take risk, while women generally tend to be more conservative (which ultimately works in favor of skilled traders). I think that the reason that we don't know or hear of more talented female traders is simply because becoming a trader and learning through research/experience is more attractive to males than females.
