Abstract
I apply a multivariate one-step testing procedure to investigate a dual-beta CAPM. I begin by establishing that there is no statistical relation between beta and returns for the standard CAPM. I then re-cast the one-step test to accommodate a dual-beta CAPM under bull and bear market conditions. When the excess market return is negative (positive), I find strong evidence of a negative (positive) relation between beta and returns. The strength of my results suggests that the success of the model is not crucially dependent on the argument for beta instability.
