For many investors, the stock market is little more than a guessing game. The stock market bubble of the late 1990s had many investors convinced that the rules of the game had changed and that this time, it really was different. What Works on Wall Street, Third Edition—with all new data through 2003— shows that it's never different this time. Armed with earlier editions of this book, investors would have avoided the devastation visited on the high risk stocks that were the favorites of investors during the bubble.

What Works on Wall Street, Third Edition, takes the guesswork out of your investment decision-making. This in-depth, updated and data-driven book looks at key strategies and benchmarks that millions of investors rely on to make their investment decisions, and tells you which of these tools have provided investors with the best longterm results.

Acclaimed author and portfolio manager James P. O’Shaughnessy presents factual, unbiased and unexpected findings that prove you can do vastly better than the market simply by consistently using stock selection strategies that have withstood the test of time. Moreover, these five decades of results warn investors to steer clear of some popular investment strategies that are toxic to your wealth.

Expanded to include how various investment strategies perform when used on All Stocks, Large Stocks, Market Leaders and Small Stocks, this new edition of the book also covers all the new research O’Shaughnessy has conducted since the last edition.

Which investment strategies are winners —and which are losers? What factors most reliably indicate that a stock will rise or fall? Are value strategies better than growth? Do small capitalization stocks do better than large? What’s the worst-case scenario for the various investment strategies and how long did it take for them to recover? Do these strategies work outside the United States?

What Works on Wall Street answers these questions and outlines a methodical, scientific, and results-based method for making intelligent stock market decisions. “To make the best investment plans for the future, investors need access to unbiased, long-term performance results,” O’Shaughnessy writes. And that is exactly what he gives you in this history-making book.
