I am assuming this isn't a troll -
If you look at investment styles, women do a much, much better job than men. Men tend to double down on terrible gambles - like Nick Leeson and the yen, or AIG and bond insurance. Women tend to cut their losses early, investigate their options very carefully and understand what they are doing.
Tests and surveys show that men tend to believe in the certitude of their good judgment, in spite of massive evidence to the contrary. They will carry a losing position way beyond any hope of salvage, and jettison it the day before it rebounds. Women are far more disciplined as investors, don't trust anyone's judgment and tend to invest within a plan and toward a defined goal.
Careful investment, strict loss management, thorough knowledge of management and investments, buy low and sell high - all characteristics that Buffett shares with the ladies.
