Hedge fund guru Leon Cooperman says stocks are the best place for investors to be in 2013. Cooperman tells CNBC that he thinks stocks “are in a zone of fair valuation to modest undervaluation”,  and that, given the Federal Reserve’s loose money policies, there’s no other asset class that can offer the kind of returns stocks can offer right now. “I think the bubble is in bonds,” Cooperman said. “Buying U.S. government bonds is like walking in front of a steamroller to pick up a dime.” Cooperman also talked about some of his favorite picks for 2013, including Crocs and Chimera Investment Corp.
