The Beta Anomaly and Mutual Fund Performance Paul Irvine Jeong Ho (John) Kim Texas Christian University Emory University Jue Ren Texas Christian University February 7, 2019 Abstract We find evidence for the beta anomaly in mutual fund performance. This anomaly is not accounted for in the standard four-factor framework, nor by the addition of a BAB factor to the benchmark model. We show how controlling for the beta anomaly produces an alternative measure of managerial skill that we call active alpha. Active alpha is persistent and associated with superior portfolio performance. Therefore, it would be sensible for investors to reward managers with high active alpha. In addition to allocating their money based on standard alpha, we find that a subset of sophisti- cated investors allocate their assets to funds with high active alpha performance.
