The first edition of Value Investing: From Graham to Buffett and Beyond was published in 2001. It is still in print, having sold over 100,000 copies. It has been translated into five languages. Business school professors still assign it in their courses. But in the 20 years since the first edition, the economy has changed, the investment world has evolved, and the discipline of value investing has adapted to this new environment. This second edition responds to these developments. It extends and refines an approach to investing that began with Benjamin Graham and David Dodd during the Great Depression and was adapted by Warren Buffett, Charlie Munger, and others to earn returns in an environment in which the opportunity to buy a stock worth a dollar for 50 cents is no longer waiting in plain sight.
