← Getty Images Warren Buffett Warren Buffettlikes bank stocks, just not investment banks. And for good reason. By avoiding common stock bets on investment banks like JPMorgan Chase, Goldman Sachs, Citigroup, and Morgan Stanley the “Oracle of Omaha’s” financial sector share investments have greatly outperformed most other investors. Of course, Buffett made preferred share investments in Goldman and Bank of America during the height of the crisis, but these were essentially super-safe loans that guaranteed a return and did not reflect his common stock plays. In fact, as Buffett continued to hold banks stocks as a key part of a U.S. economic recovery investment, the value investing guru has kept his chips smartly behind Wells Fargo — which is projected to end 2012 as America’s most profitable bank — even if the battered share prices, titanic balance sheets, and boom and bust earnings of money center giants lure some of the sectors smartest investors into sub-par investments.
