Are you presently working for a hedge fund or major bank? May Jeremey Grantham, chairman of Grantham, Mayo, Van Otterloo & Co. (via us) suggest that you get the hell out of there, because most of you are going to die anyway? That’s right, Dealbreakettes, according to Grantham, credit-market declines are going to force “as many as half”-- half, 50%, 1 of every 2-- of all hedge funds to close in the next five years. Last year 717 hedge funds closed, leaving 9,800 in business. Ergo, FOUR THOUSAND NINE HUNDRED of you are soon to be history (we did the math). Oh, and at least one global bank (gut instinct: Goldman Sachs) and “one or two” of the largest private equity firms, because those assholes have it coming. Grantham can make such apocalyptic forecasts for 2012 because he is 68, and may very well be dead by then. Grantham, Mayo, Van Otterloo & Co will survive, presumably.
