Bought 37.50 May Call Options on BAC

Bank of America will report earning next week monday. Since the market sentiment is doing pretty well now and Citigroup also reporting narrower loss, I think it's the turn around time for financial institution. I bought BAC 37.50 May call options at 2.40. Furthermore, when Bank of America report loss last quarter and totally miss the estimate, the stock actually went up. I hope I'm right!
