Well, the for broke part is hopefully a pun. But based on their most recent holdings, which among others include 104% of the IYR Real Estate ETF, Credit Suisse is certainly ploying something here (one hopes, or else that is one big fat finger). When you have the balance sheet of the Swiss National Bank to back you up, you don't really care much if you overload the boat. Of course, this is excatly what Boaz Weinstein was thinking when the world blew up in his face.
