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...

Political Econom. 116(5) 810-836) and Foster and Hart (Foster, D. P., S. Hart. 2009. An operational measure...

Stocks with large increases in call implied volatilities over the previous month tend to have high future returns while stocks with large increases in put implied volatilities over the previous month tend to have low future returns. Sorting stocks ranked into decile portfolios by past call...

Sorting stocks ranked into decile portfolios by past call implied volatilities produces spreads in average returns of approximately 1% per month,...</p>

For non-US stocks of firms in the G7 countries, we empirically test the new issues puzzle -- stocks of firms that issue new equity are, on average, very poor investments relative to various benchmarks -- by market capitalization. Only for the United Kingdom do we find evidence for a...

Motivated by existing evidence of a preference among investors for assets with lottery-like payoffs and that many investors are poorly diversified, we investigate the significance of extreme positive returns in the cross-sectional pricing of stocks. Portfolio-level analyses and firm-level...

We show that this result is driven by small stocks traded on the...
