Keith O'Malley, 30
Another grizzled 30-year-old, continues to give Hold Brothers -- and prop trading in general -- a good name. In just the first five months of 2008, O'Malley reportedly matched his entire profits of 2007 (he was said to have made a killing the day BofA announced it was taking over Countrywide), and he is apparently on a pace to make eight *figures this year. Not surprisingly, he's considering starting his own hedge fund.
