The part that I thought was most interesting was that he structures his fund as 190% passive long and 90% active short. This way, his short fund (which has average annualized returns of -0.7%) can still allow him to make a lot of money.
I like the idea that a short fund can make money if they can beat the negative of the passive index - so if the S&P returns 10%, and I can have a short fund that returns -5%, I can use his strategy to outperform the S&P.
