We examine when anomaly returns occur in order to understand if they exist. If anomalies are spurious, then anomaly returns should not depend on their proximity to the dates on which key anomaly information is released. Yet, they do. Using a powerful database containing the precise release date...

Non-fundamental demand shocks have significant effects on asset prices, but observing these shocks is challenging. We use the exchange traded fund (ETF) primary market to study non-fundamental demand. Unique to the ETF market, specialized arbitrageurs called authorized participants correct...

We show that short interest is arguably the strongest known predictor of aggregate stock returns. It outperforms a host of popular return predictors both in and out of sample, with annual r-squared statistics of 12.89% and 13.24%, respectively. In addition, short interest can generate utility...

Using daily equity lending data, I find that short sales lead to significant price pressure, consistent with inelastic short-term demand curves for stocks. Because short sales and returns are endogenously determined, I use an instrumental variables framework to identify their relation....
