In an important paper called “Boys Will Be Boys,” two economists at the University of California, Brad Barber and Terrance Odean, analyzed the brokerage records of 35,000 personal investors over the period 1991–1997 and found that single women outperformed single men by 1.44 percent. A similar result was announced in 2009 by Chicago-based Hedge Fund Research, which found that over the previous nine years hedge funds run by women had significantly outperformed those run by men.
