Irrational Exuberance Reconsidered: The Cross Section of Stock Returns

In the world of finance, understanding the cross-section of stock returns is a topic of paramount importance for both scholars and practitioners. "Irrational Exuberance Reconsidered: The Cross Section of Stock Returns" delves deeply into this complex and intriguing subject. Authored by Dr. Mathias Külpmann CFA, this book provides a comprehensive analysis of stock market behavior, drawing on theoretical insights and empirical tests. It challenges conventional wisdom and introduces innovative perspectives on asset pricing, offering readers invaluable insights into market dynamics.

Detailed Summary of the Book

The book begins by revisiting the concept of "irrational exuberance," originally popularized by Alan Greenspan. This idea has often been cited in discussions about market bubbles and investor behavior. Dr. Külpmann builds upon this foundation, examining how mispricings and anomalies in stock returns can be attributed to behavioral biases and market inefficiencies. He explores the intricate relationships between asset prices, risk factors, and investor psychology.

Using a blend of theoretical models and empirical observations, the author evaluates various asset pricing theories, including the Capital Asset Pricing Model (CAPM), Fama-French three-factor model, and others. The book challenges these models by providing evidence of anomalies that they fail to explain, such as momentum, size, and value effects in stock returns. Through exhaustive research, Dr. Külpmann also sheds light on the role of macroeconomic factors and global influences on stock return predictability.
