Positive stock information in out-of-the-money option prices

•We examine whether the option market can lead the stock market with respect to positive in addition to negative price discovery.•We utilize the Risk-Neutral Skewness (RNS) of the underlying stock’s return distribution to capture the relative expensiveness of out-of-the-money calls and puts.•We find that a long-only portfolio of stocks with the highest RNS values yields significant positive alpha in the post-ranking week during the period 1996–2014.•We propose and empirically validate a trading mechanism according to which investors choose to exploit perceived stock underpricing by buying (selling) OTM call (put) options, rather than directly buying the underlying stock, to avoid exposure to its potential downside risk.•We show that the price correction signaled by RNS is very quick, typically overnight, due to the absence of severe limits-to-arbitrage for the long side. We examine whether the option market leads the stock market with respect to positive in addition to negative price discovery. We document that out-of-the-money (OTM) option prices, which determine the Risk-Neutral Skewness (RNS) of the underlying stock return’s distribution, can embed positive information regarding the underlying stock. A long-only portfolio of stocks with the highest RNS values yields a significant positive alpha in the post-ranking week during the period 1996–2014. This outperformance is mainly driven by stocks that are relatively underpriced but are also exposed to greater downside risk. These findings are consistent with a trading mechanism where investors choose to exploit perceived stock underpricing via OTM options due to their embedded leverage, rather than directly buying the underlying stock to avoid exposure to its potential downside. Due to the absence of severe limits-to-arbitrage for the long-side, the price correction signalled by RNS is very quick, typically overnight.
