Traditional performance evaluation measures do not account for tail events and rare disasters. To address this issue, we reinterpret the riskiness measures of Aumann and Serrano (2008) and Foster and Hart (2009) as performance indices. We derive the moment properties of these indices and their...

We generalize the concept of "systematic risk" to a broad class of risk measures potentially accounting for high distribution moments, downside risk, rare disasters, as well as other risk attributes. We offer two different approaches. First is an equilibrium framework generalizing the Capital...

Traditional performance evaluation measures do not account for tail events and rare disasters. To address this issue, we reinterpret the riskiness measures of Aumann and Serrano (Journal of Political Economy, 2008) and Foster and Hart (Journal of Political Economy, 2009) as performance indices....

We propose a methodology for estimating option-implied forward-looking variances and covariances of assets and portfolios, which may not possess actively-traded options. Our approach relies on the observation that any factor structure for stock returns naturally induces a factor structure for...

We offer an approach for recovering option-implied time-varying forward-looking risk premia of systematic factors---even if they do not possess actively-traded options. We apply this approach to the market, size, value, and momentum factors. We find that factor premia are highly volatile. Both...
