Jim Cramer liked the buys, though he said that what the banks really need "to make the bears stop growling" is more capital. At Stockpickr, we track the recent insider purchases and buybacks for investors interested in piggybacking these moves. The perfect setup is threefold: insiders buying the stock, the company buying back its own shares and a super investor such as Warren Buffett also making a bullish bet on the stock. If we can get three out of three, we're in heaven. If we can get two out of three, or even one out of three, we're still pretty happy about the situation, particularly if the stock is cheap in other ways as well. To read more, visit Stockpickr.com.
