When Two Anomalies Meet: The Post–Earnings Announcement Drift and the Value–Glamour Anomaly

Abstract

This study of the post–earnings announcement drift and the value–glamour anomaly finds that value stocks have greater information uncertainty, exhibit more-muted initial market reactions to earnings surprises, and have better (more positive or less negative) post–earnings announcement drifts than do glamour stocks. A trading strategy based on these findings can generate an average annual abnormal return of 16.6–18.8 percent before transaction costs.
