TheStreet's Jim Cramer says Yahoo's earnings report was "terrific" and not just because of Alibaba. Cramer says Yahoo's business has stabilized away from Alibaba and it will be able to buy back billions of dollars worth of stock. Cramer thinks the stock can trade to the mid-$40s. Bank of America did not have a stellar quarter, says Cramer, and if the stock was up 44 cents yesterday it will give back those gains today. Cramer would buy the stock below $15, the level at which it will stabilize.
