Ultimately, Hagstrom shows how to use this technique to achieve the best possible results. In order to clearly outline the strategies and philosophies of focus investing, this book draws on Warren Buffett and others including John Maynard Keynes and Philip Fisher, Bill Ruane, Lou Simpson, and Charlie Munger
