Master Profile
Edgar Wachenheim III's investment career, philosophy, and public 13F holdings through Greenhaven Associates.
Little public information is available about Wachenheim III’s early life. His academic background is outstanding: he earned his undergraduate degree from Williams College and later received an MBA from the prestigious Harvard Business School. This education laid a solid foundation for his subsequent use of case-method analysis in making investment decisions.
Wachenheim began his career at Goldman Sachs as a securities analyst, where he sharpened his company analysis skills. In 1987, he founded his own investment management firm—Greenhaven Associates. Under his leadership, Greenhaven manages approximately $8.5 billion in assets for wealthy families, university endowments, and charitable foundations. His investment track record is outstanding. Over a 30-year period (1990–2021), the equity portfolio he managed delivered an annualized return of roughly 18%, significantly outpacing the S&P 500 index over the same horizon. His investment style tends to be conservative, and he does not use leverage to amplify returns, reflecting his emphasis on risk control.
The core of Wachenheim’s investment philosophy can be summed up as “common stocks and common sense.” His key principles are as follows: Seek undervalued quality growth companies: His core strategy is to buy shares of strong, high-quality growth companies that are significantly undervalued. He expects positive future developments (such as a cyclical industry upturn, a successful cost-cutting program, or a management change) to drive substantial price appreciation, and these positive factors must not yet be fully recognized by the market. Emphasize margin of safety: He places great weight on investment safety, insisting that the purchase price must be well below his estimate of intrinsic value. He often uses a vivid analogy: if an elevator is rated to carry 270 kg and two people weighing about 90 kg each are already inside, he, weighing 80 kg, would not enter because the margin of safety is insufficient. He would choose an elevator occupied only by a slim little old lady to secure a higher margin of safety. In his IBM investment case, based on his forecast of cost-cutting potential and reasonable earnings, he bought shares at $11–12, believing the stock could be worth $20–21 in 1995—this illustrates his pursuit of a margin of safety. Investing combines probability and behavioral psychology: He believes successful investing requires not only analytical ability but also behavioral discipline. This includes the willingness to make decisions contrary to the prevailing market view, sufficient confidence to draw conclusions based on assessments of future probabilities (rather than simply extrapolating recent trends), and the ability to control emotions under stressful and difficult conditions. Focus on value two to three years out: His investment decisions are based on forecasts of a company’s value two to three years into the future, not on short-term market fluctuations. He does not believe that shares of great companies must be “held forever”; if the stock price has fully reflected the value, he will sell to realize profits. For example, after IBM’s share price rose, he sold the initial position above $16, locking in a gain of over 40%.
Outside work, Wachenheim is actively involved in philanthropy. He has served as chairman of the board of WNET, America’s flagship public television station, a trustee of the Museum of Modern Art, and a life trustee of the New York Public Library, among other roles. He believes that participating in these board activities teaches him a great deal, making him a better investor. He lives with his wife in Rye, New York, and has a large family that includes four adult children and seven grandchildren.
Wachenheim has systematically codified his investment wisdom in his book Common Stocks and Common Sense. The book uses the Harvard Business School case method, dissecting in detail 12 real investment cases including IBM, Boeing, and Lowe’s, and thoroughly presenting his investment process, thought processes, and insights into investment psychology. The final chapter is a letter he wrote in reply to a young investment manager, summarizing his investment strategy and listing 24 practical investment tips.
