The first finding is consistent with a model predicting that negative asymmetries are more likely to occur when there are large differences of opinion among investors. The latter finding fits with a number of theories. Analogous results also obtain when the authors attempt to forecast the skewness of the aggregate stock market, although here their statistical power is limited.
