摘要:

This paper analyzes the consequences of the discovery of anomalies. It shows that consistent with existing evidence, the discovery of an anomaly reduces its magnitude and makes it more correlated with other existing anomalies. One new prediction is that the discovery reduces the correlation between the two portfolios in the anomaly (e.g., the value and growth portfolios in the value anomaly). We empirically test this prediction for value, size, and momentum anomalies, and find clear evidence consistent with this prediction. Our model also sheds light on how to distinguish risk- and mispricing-based anomalies.
