Although Warren Buffett let go of his Goldman Sachs stock, the Wall Street investment bank has others waiting in the wings just waiting to buy them up. The Greenhaven Associates firm bought another 39,533 shares, giving them a total of 2,947,430 of stocks worth $582.5 million in total for the second quarter. Ironically, the firm also has stakes in Buffett’s Berkshire Hathaway, as well as GM, Lennar and Morgan Stanley.
