Several theoretical studies suggest that coordination problems can cause arbitrageur crowding to push asset prices beyond fundamental value as investors feedback trade on each others' demands. Using this logic we develop a crowding model for momentum returns that predicts tail risk when...

External imbalance is a central variable in international economics and recent research shows it is priced in currency portfolios. But Ang et al. (2017), among others, show that with a small and time-varying cross section, tests with individual assets are preferable. We find testing with...

A direct measure of the cyclicality of momentum at a given point in time, its bottom-up beta with respect to the market, forecasts both the returns and the risk of the strategy. Challenging a potential risk-based explanation, a highly cyclical momentum portfolio forecasts both higher risk and...

Compared with the market, value, or size factors, momentum has offered investors the highest Sharpe ratio. However, momentum has also had the worst crashes, making the strategy unappealing to investors who dislike negative skewness and kurtosis. We find that the risk of momentum is highly...

We examine the time-series risk-return trade-off among equity factors. We obtain a positive trade-off for profitability and investment factors. Such relationship subsists conditional on the covariance with the market factor, which represents consistency with Merton's ICAPM. Critically, we obtain...

We examine the risk-return trade-off among alternative equity factors. We obtain a positivein-sample trade-off for the pro fitability (RMW) and investment (CMA/IA) factors of Famaand French (2015) and Hou, Xue, and Zhang (2015), while for the market and momentumfactors there is a negative...

After long being one of the main puzzles in asset pricing, momentum has ironically became a case of observational equivalence. It can now be explained both by factors proxying for mispricing and by the risk-based q-factor theory. On top of this, q-factor theory also explains the related...
