One of the main explanations for the idiosyncratic volatility (IVOL) puzzle (i.e., the negative relation between lagged … IVOL and returns) is a missing risk factor. We show analytically that if IVOL proxies for a missing risk factor, then the … risk factors. Overall, our results suggest that both diversifiable (i.e., true idiosyncratic risk) and non …
