"Building a concentrated portfolio is critical for investment success. The Warren Buffett Portfolio introduces the next wave of investment strategy, called focus investing. A comprehensive investment strategy used with spectacular results by Buffett, focus investing directs investors to select a concentrated group of business by examining their management and financial positions as compared to their stock prices. A strategy that has historically out-performed the market, focus investing is based on the principle that a shareholder's return from owning a stock is ultimately determined by the economics of the underlying business." "Hagstrom explains in easy-to-understand terms exactly what focus investing is, how it works, and how it can be applied by any investor at any level of experience."--Jacket.
