Gender Differences in Investing

Fascinating read this morning on the differences in the way men and women invest their money. Surprise, surprise, men are less risk-averse (how often do you see women doing insanely risky things in everyday life? I mean, they are simply much smarter than we are). But in investing, risk equals reward, so there is a chance that women's conservatism leaves money on the table.

I found it interesting to see toward the end of the story, that mixed gender investment clubs actually did better than single gender. Wisdom of the crowd at work?
