The study has investigated the impact of trading costs and short sale constraints on the performance of 70 stock market anomalies in Emerging Europe. While over 30 of the replicated strategies – mostly related to value, momentum, technical analysis, profitability, and issuance effects –...

We show that short sellers are constrained by their losses. Using unique data on the mark-to-market profits of short sellers of U.S. stocks, we document an asymmetric response of short selling to gains versus losses. Short selling substantially falls following large losses but does not respond...

We use a heterogeneous agent model to explain market crashes resulting from an unanticipated deleveraging shock. In a market with short sale constraints, when the opinions of investors diverge substantially, the market price is set by the demand schedule of optimistic investors while pessimistic...

This paper analyzes how newly introduced transparency requirements for short positions affect investors' behavior and security prices. Employing a unique data set, which contains both public positions above and confidential positions below the regulatory disclosure threshold, we offer several...

This paper examines the interrelation between short selling and volatility as differing from previous research in that it focuses on intraday activities, rather than the daily price movements. We demonstrate that the effects of short selling activity change during the two sessions of the day and...

Studying a large sample of publicly available data on failures to deliver, we find that stocks reaching threshold levels of failures become significantly overvalued. Where short sale constraints are especially binding, we report extreme overpricing and subsequent reversals. These findings...

We examine if differences in short selling volumes and the information impounded by short sells can contribute to explaining pricing differences which exist between the A- and H-share markets in China. In particular, we argue and also find that informed short selling around earnings...

This paper examines the impact of naked short selling on equity markets where it is restricted to securities on an approved list. Consistent with Miller's (1977) intuition, stocks with the highest dispersion of opinions and short sale constraints are the only stocks to exhibit significant and...

On October 26, 2008, Porsche announced a largely unexpected domination plan for Volkswagen. The resulting short squeeze in Volkswagen's stock briefly made it the most valuable listed company in the world. We argue that this was a manipulation designed to save Porsche from insolvency and the...
