We find that news-based measures of economic policy uncertainty (EPU) negatively forecast momentum. A one standard deviation increase in EPU is associated with a 1.11% decrease in risk-adjusted momentum returns. The predictive power of EPU is robust after controlling for previously documented...

We investigate how the interaction of entries and exits of informed institutional investors with market anomaly signals affects strategy performance. The long legs of anomalies earn more positive alphas following entries, while the short legs earn more negative alphas following exits. The...

We examine the causal effect of short-selling on a firm's annual report readability using Regulation SHO, which relaxes short-sale constraints for a random sample of pilot stocks. Pilot firms' annual report readability decreases during the experiment period. This short-selling effect on 10-K...

Whether or not anomalies are due to mispricing or risk is an important question. We examine the causal effect of a novel shock to short selling, the Job and Growth Tax Relief Reconciliation Act (JGTRRA) of 2003, on an extensive set of 182 anomalies. We find that anomalies become stronger after...

This paper investigates the causal impact of short-sale constraints on the idiosyncratic volatility (IVOL) puzzle. Our identification strategies rely on two opposing exogenous shocks to short-sale constraints: (1) Regulation SHO which relaxes constraints for pilot stocks; (2) the Job and Growth...
