The value of columnists’ stock recommendations: an event study approach

The value of columnists’ stock recommendations: an event study approach This study examines the value of stock recommendations made by columnists in three leading business magazines; Business Week, Forbes, and Fortune during the period 2000–2003. Empirical results suggest that the anomalous returns documented in prior studies on columnists are sample specific and are not representative of columnist recommendations in general. We also investigate whether columnists’ timing, content and style affect the market reaction to recommendations. We find that recommendations that contain references to management or provide merger & acquisition related rumor trigger significantly greater market reactions. Finally, our long-term performance analysis of columnist recommendations suggests that investors following columnists’ advice during the 2000–2003 period would not have consistently earned abnormal returns controlling for market risk, book-to-market, size, and momentum effects. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Review of Quantitative Finance and Accounting Springer Journals

Abstract

This study examines the value of stock recommendations made by columnists in three leading business magazines; Business Week, Forbes, and Fortune during the period 2000–2003. Empirical results suggest that the anomalous returns documented in prior studies on columnists are sample specific and are not representative of columnist recommendations in general. We also investigate whether columnists’ timing, content and style affect the market reaction to recommendations. We find that recommendations that contain references to management or provide merger & acquisition related rumor trigger significantly greater market reactions. Finally, our long-term performance analysis of columnist recommendations suggests that investors following columnists’ advice during the 2000–2003 period would not have consistently earned abnormal returns controlling for market risk, book-to-market, size, and momentum effects.
