Some investment books claim only one true path to stock-market riches. Fund manager James O'Shaughnessy has five, and he has the data to back them up. He was the first independent researcher to be granted full access to a Standard & Poor's database containing computerized information on almost 10,000 stocks going back to 1951. From the data, O'Shaughnessy derived five portfolio-building strategies that, over the past 45 years, have consistently beaten the market average. How to Retire Rich also contains a wealth of useful information on mutual funds, online trading, and using the Internet to research stocks.

From Library Journal
The author, a statistical analyst and founder and president of O'Shaughnessy Capital Management, Inc., builds on his previous What Works on Wall Street (McGraw-Hill, 1996) to demonstrate how investing in the stock market can lead to wealth and security in one's later years: "The path to achieving investment success is in studying long-term results and finding a strategy or group of strategies that make sense." O'Shaughnessy offers strategies based on historical perspective that should beat the Standard & Poor 500 because they involve aggressive investing in not-so-well-known smaller companies. In addition to strategies, he covers good and bad points of mutual funds, making the most of 401k plans, market fluctuations, portfolio management, and a timely chapter on where to find information. This often-quoted author's opinions are presented in a readable style, with several family scenarios providing perspective.
