What Works on Wall Street, Fourth Edition

In this book, James P. O'Shaughnessy presents a detailed analysis of various investment strategies that have historically outperformed the market.

He challenges conventional wisdom by using back-tested data to show that strategies combining value, size, momentum, and quality factors tend to achieve higher returns with manageable risk.

The book covers a wide range of topics, including price-to-book ratios, dividend yields, buyback yields, and multifactor models, providing insights into how these strategies can be implemented to enhance investment performance.
