Are men and women that different when it comes to trading?

SSRN-An Experimental Test of the Impact of Overconfidence and Gender on Trading Activity by Richard Deaves, Erik Lueders, Rosemary Guo Ying Luo

Do you remember the findings during the internet wave that female investors showed more patience and did not suffer from the same overconfidence that afflicted some male investors? Well, work by Deaves, Luenders, and Luo now draw that into question.

While the new work does find that over confidence leads to excessive trading, "women have about the same level of both overconfidence and trading activity as do men."
