Book excerpt: Deep insight and candid discussion from one of Wall Street's best investors Common Stocks and Common Sense provides detailed insight into common stock investing, using a case-study approach based on real-world investments. Author Edgar Wachenheim is the 28-year CEO of Greenhaven Associates, boasting an average annual portfolio comparable to Warren Buffet's. In this book, he shares his knowledge and experiences by providing detailed analyses of actual investments made by himself and other investors. The discussion covers the entire investment process, including the softer, human side, with candid insight into the joys and frustrations, intensities and pressures, and risks and uncertainties. The unique emphasis on behavioral economics and real-world cases set this book apart from the herd—but it's Wachenheim himself and his deeply-examined perspective that elevates the book beyond a mere investing guide. Between 1990 and 2014, a typical portfolio managed by Wachenheim enjoyed an average annual return in excess of 18%, achieved using relatively conservative stocks and no financial leverage. As a proponent of evidence and example, his analysis of real cases serve as a valuable education for anyone looking to improve their own investment practices.
