In the intricate tapestry of market anomalies, Zhipeng Yan and Yan Zhao weave a compelling narrative in their 2011 exploration titled “When Two Anomalies Meet: The Post-Earnings Announcement Drift and the Value-Glamour Anomaly.”
Venturing into the confluence of these anomalies, the authors unravel a tale where value stocks, shrouded in information uncertainty, emerge as protagonists. Their journey through market reactions to earnings surprises unveils a nuanced dance: value stocks, initially more stoic, boast superior post-earnings announcement drifts compared to their glamour counterparts.
The implications are profound—an ingenious trading strategy born from these insights yields an average annual abnormal return of 16.6-18.8 percent, a testament to the power hidden within the intricate interplay of market anomalies.
Abstract Of Paper
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.
