According to Wikipedia:
The article has been reprinted in books about Buffett (e.g. Miles, 2004).”The Superinvestors of Graham-and-Doddsville” is an article by Warren Buffett promoting value investing, published in the Fall, 1984 issue of Hermes, Columbia Business School magazine. It was based on a speech given on May 17, 1984 at the Columbia University School of Business in honor of the 50th anniversary of the publication of Benjamin Graham and David Dodd‘s book Security Analysis. The speech and article challenged the idea that equity markets are efficient through a study of nine successful investment funds generating long-term returns above the market index. All these funds were managed by Benjamin Graham’s alumni, pursuing different investment tactics but following the same “Graham-and-Doddsville” value investing strategy.
