Abstract

We show that the negative relation between idiosyncratic volatility (IVOL) and expected returns exists only among firms with low profitability and high uncertainty about profitability. We propose an incomplete information model in which agents cannot disentangle systematic from idiosyncratic shocks. While not priced directly, IVOL affects expected returns by lowering signal accuracy, which decreases the factor loading on the priced systematic risk and yields the negative IVOL-return relation. The model predicts that this negative relation is the strongest among underperforming firms with highly uncertain profitability. We empirically confirm cross-sectional predictions related to both firm profitability and fundamental uncertainty. Our model effectively explains a significant portion of the observed negative IVOL-return relation (86\%) in data.

Keywords: Idiosyncratic volatility, Bayesian updating, incomplete information, uncertainty, firm profitability
