Edgar Wachenheim is the Founder and Chief Executive Officer of Greenhaven Associates, an investment firm established in 1987. His investment strategy can be classified as value-oriented as he pays little regard to the current price of stocks and focuses more on the actual value of companies. In his famous interview with Jim Cramer in 2018, Wachenheim mentioned that he buys deeply undervalued stocks as they have the potential to yield bigger returns for shareholders. As a proponent of evidence and example, Wachenheim's analysis of real cases serves as an invaluable education for anyone looking to improve their own investment practices.
