Maybe - I actually don't think it's very interesting, because I doubt "women" are the deciding factor. It seems more likely to me that women prefer certain types businesses, that for random chance did well in recent years (ie Social Networks vs mining or car manufacturing). I dug up one of those papers, by Credit Suisse, and it was exactly as I thought: counting from 2006 onwards women led companies performed better than others. But if women were the factor, why didn't that effect show before 2006? (Not sure if it was exactly 2006, but some recent year). It's well known that if you are allowed to pick the time frame, you can make any investment look good ("if you bought stock x in year y, you would have tripled your investment in 10 years" - but you would have lost everything in year 11...).
