CNNMoney reports that Bank of America (NYSE: BAC) reports that its earnings fell 41% in the second quarter to 72 cents a share. In response, its stock is up 11% in pre-market. Why the celebration? Analysts expected Bank of America's earnings to tumble 48% to 53 cents, so it beat those expectations by 19 cents a share.

According to CNNMoney. Bank of America's revenue was up 14.6% to $20.32 billion during the quarter due to "wider net interest margins, loan growth and higher income from mortgage banking and the company's investment and brokerage services." Thomson Reuters surveyed analysts who expected revenue of $18.37 billion -- 10% lower than its actual results.

I am wondering whether some investors will think we have bottomed out of the banking crisis. I think it's too early to break out the champagne, but the coming rally could be a good time for nervous investors to bail out. That's because credit losses could keep rising -- Bank of America added $5.8 billion to reserves for bad loans and its Countrywide purchase could boost those reserves far more in coming quarters.
