This study evaluates the relationship investor sentiment, exchange rate volatility, net foreign portfolio investment and the country index crash risk. The moderating variable, net foreign portfolio investment, is introduced. While previous crash risk studies typically focus on individual firms,...

We apply machine learning techniques and use stock characteristics to predict the cross-section of stock returns in 33 international markets. We conduct a stringent out-of-sample test to examine concerns about overfitting: the models are trained with past U.S. data and used to predict...

A unified explanation of risk and mispricing in stock returns underpinned by their aggregate liquidity risk is presented. We argue alternating liquidity exposures depict two distinct investment preferences-hedging against aggregate liquidity risk or betting on it. A three-factor model capturing...

A mechanical rebalancing strategy, such as a monthly or quarterly reallocation towards fixed portfolio weights, is an active strategy. Winning asset classes are sold and losers are bought. During crises, when markets are often trending, this can lead to substantially larger drawdowns than a...

We document that the variation in market liquidity is an important determinant of momentum crashes that is independent of other known explanations surfaced on this topic. This relationship is driven by the asymmetric large return sensitivity of short-leg of momentum portfolio to changes in...
