In literature, many researchers focus on information contained in stochastic volatility dynamics, such as CBOE VIX index and its risk premium. However, there are relatively fewer studies on stochastic skewness dynamics. Simple linear regression indicates that stochastic volatility and stochastic...

We study the relation between option-implied skewness (IS) and the cross-section of option returns under daily hedging to better understand the pricing of skewness in isolation from lower moments. Creating portfolios of delta-hedged (D-hedged) and delta-vega-hedged (DV-hedged) options with daily...

This paper presents a tractable dynamic equilibrium model of stock return extrapolation in the presence of stochastic volatility. In the model, consistent with survey evidence, following positive (negative) stock returns, investors expect future returns to be higher (lower) but also less (more)...

Divergence in investor beliefs is an important driver of the negative relation between option trading volume and future stock returns. We find a strong negative relation between disagreement-based option trades and future stock returns, and this relation is markedly amplified when the underlying...

Prior literature finds information is reflected in option markets before stock markets using daily and weekly trading volume, but evidence is mixed at the intraday level. Using novel intraday signed option volume data, we develop a composite option trading score (OTS) and document its stock...

The option implied volatility spread and skew predict stock returns. These variables also reflect the expected cost of borrowing stock to sell short. The stock borrowing fee implied from options prices predicts changes in quoted borrowing fees and stock returns; however, the volatility spread...

We uncover new return predictability in the cross-section of delta-hedged equity options. Expected returns of writing delta-hedged calls are negatively correlated with current stock price, firm profit margin and profitability, but positively correlated with firm cash holding, cash flow variance,...

This paper studies the effects of default risk on equity option returns. We show that there is a cross-sectional and a time-series relation between default risk and option returns. In the cross-section, expected delta-hedged equity option returns have a negative relation with default risk...

Motivated by the theory of demand-based option pricing in imperfect markets, we examine the relation between short-sale constraints and equity option returns, conditional on the level of mis-pricing in the underlying stock. We report a monotonic relation between various measures of short-sales...

Equity option markets exhibit intense trading activity. We use the variability of option implied volatility spread as a proxy for the impounding of new information, and changes in the interpretation of existing information, into option prices. Over the 2006 – 2016 period, we find that the...
