Bill Nygren, whose three Oakmark funds have excelled in 2009 and have strong long-term track records, remains bullish as we head into 2010. Nygren tells CNBC that he’s “very positive” on stocks, and cites the high pessimism in the market as a big reason. He says there are values “all over the place”, and adds that his strong ’09 performance is attributable to staying disciplined through the market turmoil.
