As if hedge funds did not have enough to worry about with redemption requests galore after last week's epic rout and vol surge, today's Google stunner acquisition of MMI caught a near record number of them with their pant down. The company, which had over the past year, ever since its spin off, become one of the most despised public companies, saw a 250% increase in its short interest since December, peaking at 25 million shares short, dropped to just under 20 million shares, or essentially the second highest to date. These are precisely the institutional shorts who are hating their live right now as they are sitting on a $260 million paper loss, enough to wipe out several mid-size hedge funds. Speaking of, following rampant rumors spread by CNBC's strategy session last week that various funds were blowing up left and right (in addition to perennial bete noire Paulson & Co of course), we have yet to hear of even one casualty. Just how tight of a lid are prime brokers keeping on their hedge fund client casualties if not one peep has been uttered about who blew up? Following today's trouncing in MMI, we doubt this secret will be such a secret for much longer.
