Abstract

We examine the relation between idiosyncratic volatility and returns around news announcements. Mispricing is most likely to occur during news announcements. If idiosyncratic volatility generates a limit to arbitrage, then the negative relation between returns and news volatility should be stronger than the relation to non-news volatility. Instead, we find non-news volatility has a robust negative relation to returns and lacks key features expected if volatility were a reflection of limits to arbitrage. Pricing of non-news volatility is related to lottery-like features of a stock's return. Our results suggest that volatility has a price effect beyond a limit to arbitrage.
