ABSTRACT

The beta anomaly indicates that high-beta stocks earn low future excess returns. We first prove the existence of the beta anomaly in the Chinese A-share stock market and then explain this anomaly based on short-sale constraints and aggregate disagreement. We provide a new proxy for aggregate disagreement based on analysts’ earnings forecasts and find that the beta anomaly does not exists in stocks with no short-sale constraints and periods with low aggregate disagreement. Furthermore, the higher level of aggregate disagreement is associated with a more concave Security Market Line and a more significant beta anomaly.

Keywords: Beta anomaly; Heterogeneous beliefs; Disagreement; Analyst forecast; short-sale constraints.
