Standard Fama-French and Carhart models produce economically and statistically significant nonzero alphas, even for passive benchmark indices such as the S&P 500 and Russell 2000. We find that these alphas arise primarily from the disproportionate weight the Fama-French factors place on small...

We use a novel sample of separate accounts to perform an out-of-sample test of the predictive power of active share (Cremers and Petajisto, 2009). While active share has limited predictive power unconditionally, it has significant power conditional on past performance. We find strong positive...

This paper considers a plethora of option-based measures of stock mispricing introduced by previous literature. These measures are based on differences between implied and actual stock prices, differences in implied volatilities across options, and on option trading volume. We show that stocks...

We examine U.S. dual and single class firms in 1980-2017, and document that the valuation difference between dual and single class firms varies over their life cycle. At the IPO, dual class firms have higher mean valuations than single-class firms, and we present evidence suggesting that this...

We show that at-the-money implied volatility of options on futures of 5-year Treasury notes (Treasury ‘yield implied volatility') predicts both the growth rate and volatility of gross domestic product, as well as of other macroeconomic variables, like industrial production, consumption, and...

We document that stocks that have optimistic (pessimistic) consensus recommendations and are currently held by many short-term institutions exhibit large stock-return reversals: their large past outperformance (underperformance) is followed by large negative (positive) future alphas. The...
