It is important to recognize that even some of the greatest investors have made huge mistakes. In 2008, many of the big value managers got killed by buying some of the big banks like Citigroup and Bank of America. If not for a bailout from the Treasury and the Federal Reserve, these companies would have gone bankrupt. In addition, short term performance means little. Tom Russo was down 2% in 1999, when the market was up 19%; and he said it was the greatest year of his investment career. He went on to post spectacular returns in the following years as the tech bubble burst, and has produced per annum returns of close to 16% for 1984.
