UBS seems to be getting hit with pretty bad news, i.e. massive job cuts, businesses being slashed, yet the stock jumped 15% today. Please correct me if I'm wrong, but the reason UBS jumped is because shorts are buying to cover. At least that's what my gut is saying. Could it possibly be that investors see the profits going up since they will no longer be issuing the 10,000 payrolls after the cuts? This seems counter intuitive, but I guess stranger things have happened. If my gut is right and it's simply the shorts buying to cover that is driving the price up, then how long till the house of cards comes crashing back down?
