Value Investing Performance

Performance, value strategies

Value investing has proven to be a successful investment strategy. There are several ways to evaluate its success. One way is to examine the performance of simple value strategies, such as buying low PE ratio stocks, low price-to-cash-flow ratio stocks, or low price-to-book ratio stocks. Numerous academics have published studies investigating the effects of buying value stocks. These studies have consistently found that value stocks outperform growth stocks and the market as a whole.[3][4][5]

Performance, value investors

Another way to examine the performance of value investing strategies is to examine the investing performance of well-known value investors. Simply examining the performance of the best known value investors would not be instructive, because investors do not become well known unless they are successful. This introduces a selection bias. A better way to investigate the performance of a group of value investors was suggested by Warren Buffett, in his May 17, 1984 speech that was published as The Superinvestors of Graham-and-Doddsville. In this speech, Buffett examined the performance of those investors who worked at Graham-Newman Corporation and were thus most influenced by Benjamin Graham. Buffett's conclusion is identical to that of the academic research on simple value investing strategies--value investing is, on average, successful in the long run.

During about a 25-year period (1965-90), published research and articles in leading journals of the value ilk were few. Warren Buffett once commented, "You couldn't advance in a finance department in this country unless you thought that the world was flat."

Well Known Value Investors

Benjamin Graham is regarded by many to be the father of value investing. Along with David Dodd, he wrote Security Analysis, first published in 1934. The most lasting contribution of this book to the field of security analysis was to emphasize the quantifiable aspects of security analysis (such as the evaluations of earnings and book value) while minimizing the importance of more qualitative factors such as the quality of a company's management. Graham later wrote The Intelligent Investor, a book that brought value investing to individual investors. Aside from Buffett, many of Graham's other students, such as William J. Ruane, Irving Kahn and Charles Brandes have gone on to become successful investors in their own right.

Graham's most famous student, however, was Warren Buffett, who ran successful investing partnerships before closing them in 1969 to focus on running Berkshire Hathaway. Charlie Munger joined Buffett at Berkshire Hathaway in the 1970s and has since worked as Vice Chairman of the company. Buffett has credited Munger with encouraging him to focus on long-term sustainable growth rather than on simply the valuation of current cash flows or assets

Another famous value investor is John Templeton. He first achieved investing success by buying shares of a number of companies in the aftermath of the stock market crash of 1929.

Martin J. Whitman is another well-regarded value investor. His approach is called safe-and-cheap, which was hitherto referred to as financial-integrity approach. Martin Whitman focuses on acquiring common shares of companies with extremely strong financial position at a price reflecting meaningful discount to the estimated NAV of the company concerned. Martin Whitman believes it is ill-advised for investors to pay much attention to the trend of macro-factors (like employment, movement of interest rate, GDP, etc.) not so much because they are not important as because attempts to predict their movement are almost always futile. Martin Whitman's letters to shareholders of his Third Avenue Value Fund (TAVF) are considered valuable resources "for investors to pirate good ideas" by another famous investor Joel Greenblatt in his book on special-situation investment "You Can Be a Stock Market Genius" (ISBN 0-684-84007-3, pp 247)

Joel Greenblatt achieved annual returns at the hedge fund Gotham Capital of over 50% per year for 10 years from 1985 to 1995 before closing the fund and returning his investors' money. He is known for investing in special situations such as spin-offs, mergers, and divestitures.
