Tuesday was a good day for Bank of America. The bank's shares rebounded 17 percent on Wall Street, making up nearly all the ground lost on Monday when the company's stock fell about 20 percent. CEO Brian Moynihan told CNBC the bank's core businesses are strong and that most the bank's divisions are doing well. He also repeated the need for B of A to move on from its mortgage-related problems. On Monday, insurance giant AIG sued the Bank of America for $10 billion over what it says was fraud related to mortgage-backed securities. Moynihan is scheduled to take questions this afternoon during a conference call with investors. That call has been organized by Fairholme Capital, which owns millions of bank shares.
