In this episode, I have three guests on the show with me: Kewei Hou of Ohio State University, Chen Xue of the University of Cincinnati, and Lu Zhang of Ohio State University.
Kewei, Chen, and Lu have coauthored a paper titled "Replicating Anomalies," a large-scale replication study that re-tests hundreds of so-called "anomalies" in financial markets. An anomaly is a predictable pattern in stock returns, or stated differently, it is a deviation from the efficient markets hypothesis. Their abstract reads as follows:
We discuss the process of replicating these anomalies, issues involving the use of equal-weighted vs value-weighted returns, and the problems of p-hacking in finance research.
