This paper proposes a generalized measure of riskiness that nests the original measures pioneered by Aumann and Serrano (Aumann, R. J., R. Serrano. 2008. An economic index of riskiness. J. Political Econom. 116(5) 810-836) and Foster and Hart (Foster, D. P., S. Hart. 2009. An operational measure...

Aumann and Serrano (2008) and Foster and Hart (2009) introduce riskiness measures based on the physical return distribution of gambles. This paper proposes model-free options' implied measures of riskiness based on the risk-neutral distribution of financial securities. In addition to introducing...

This is the first study on the risk-neutral distribution of option returns. We derive solutions for the risk-neutral variance, skewness, and kurtosis of call and put option returns and document several properties of these ex-ante moments. We find that the volatility, skewness, and kurtosis of...

We propose a theoretically motivated and empirically robust factor model for option returns. The model consists of factors based on option illiquidity, option price, implied-minus-realized volatility, implied-minus-realized skewness, implied-minus-realized kurtosis, and the option market factor....

We introduce a new approach to measuring riskiness in the equity market. We propose option implied and physical measures of riskiness and investigate their performance in predicting future market returns. The predictive regressions indicate a positive and significant relation between...

We propose options' implied and physical measures of riskiness and investigate their performance in predicting future returns on the U.S. equity market. The predictive regressions indicate a positive and significant relation between time-varying riskiness and expected market returns. The...
