Abstract

This study provides strong evidence that the analyst dispersion anomaly (i.e., higher analyst forecast dispersion predicting lower future returns) exhibits a state-dependent pattern: the negative dispersion-return relation is evident only among stocks with high investor optimism but attenuates or even reverses among stocks with high investor pessimism. Reduced investor risk aversion and binding short-sale constraints amplify the anomaly under the condition of high investor optimism. These findings together align with Atmaz and Basak’s (2018) theory that disagreement combined with expectation biases causes mispricing. Alternative mechanisms, including managerial strategic disclosure, intertemporal hedging demand, credit risk, and analyst self-censorship,fail to subsume this conditional pattern. We also show that several other well-known measures of disagreement exhibit a similar state-dependent property. Overall, this study provides novel insights into the mechanisms driving the dispersion anomaly.
