We show that much of the profitability in equity option return strategies, which try to capture option mispricing by taking exposure to underlying volatility, can be explained by an IPCA model. The alpha reduction, relative to competing static factor models, is between 50% and 75% depending on...

We combine risk-neutral densities from equity index options with realized index returns to estimate the market's risk aversion. Starting from a power utility framework with constant risk aversion, we extend it by more flexible stochastic discount factors. We allow for time-varying risk aversion...

This paper presents a new robust predictor for option returns: the uncertainty of put-call parity violation (VVS). We find that the delta-hedged equity option return decreases monotonically with VVS. Although VVS is highly correlated with the classical uncertainty and limit-to-arbitrage...

We show that much of the profitability in equity option return strategies, that try to capture option mis-pricing by taking exposure to underlying volatility, can be explained by an IPCA model. The alpha reduction, relative to competing static factor models, is between 50% and 75% depending on...

In this study, we investigate the determinants of convenience yields across a broad range of commodities. We find that the convenience yields of commodities are exposed to both commodity-specific and systematic factors, but to a different extent. The difference in explanatory power of these...

We study the role of analysts and options traders in the information transmission between options and stock markets. We first show that the predictive power of option implied volatilities (IVs) on stock returns more than doubles around analyst-related events, indicating that a significant...

We exploit information in option prices in order to study whether the ex post responsiveness of tock prices to earnings information is reflected from an ex ante, firm- and quarter-specific perspective. Specifically, we develop a measure of anticipated information content (AIC) that isolates the...

This study investigates whether a lead-lag relationship exists between the returns and the moments of the implied risk-neutral density (RND) in Korea Composite Stock Price Index (KOSPI) 200 spot, futures, and options markets. The empirical analysis suggests that although there is a...

We use a new approach to assess the information transmission between options and stock markets. We study whether the predictive power of option-implied volatilities (IVs) on stock returns lies in analyst-related and/or earnings-related news. We find that two proxies for options trading (IV skew...

While numerous prior studies report that call–put implied volatility spreads positively predict future stock returns, recent literature shows that the predictive relation is negative for future call option returns. We investigate whether and, if so, how the predictive relation for options...
