Abstract

This paper investigates cross-sectional variation in stock returns over the trading day and overnight. Contrary to placebo anomalies, which earn most of their returns overnight, several well-known anomalies earn their returns either near the close or gradually throughout the day. Hedging risk can explain part of the cross-sectional return variation over the day. Investor clientele effects around market closures are also supported. Anomalies that perform well over the trading day perform poorly both at the open and at the close. The low returns around the close are consistent with mispricing due to short-selling constraints.
