The report wasn't bad, maybe investors expected another dividend hike? It also could be do to the fact that the perception is that litigation for mortgage "misdeeds" is moving down the food chain and into the regionals. Like shaggy says, who knows?
i dont buy the litigation part because all the other big regionals like FITB and Hban have been moving up. There is more to this downward move considering the very high volume of shares this early. who is selling.
