In response to the sharp decline in prices of financial stocks in the fall of 2008, regulators in a number of countries banned short selling of particular stocks and industries. Evidence suggests that these bans did little to stop the slide in stock prices, but significantly increased costs of...

Regulating short selling is difficult and controversial. We review the academic literature on short selling regulation and provide insights for future policymakers and academics. We organize the complex history of short selling regulation into three areas: disclosure requirements, securities...

This paper investigates short selling behavior, particularly by foreign investors, during event days of non-normal times on an intraday basis in the Korean stock market around the global financial crisis. Although, in the several subsamples, we cannot exclude the predatory short-selling...

This paper investigates two issues: whether there is heterogeneity for fund managers as investors and whether there is asymmetric volatility under short-sale constraints. If so, what are the driving factors in the Korean fund market? Fund return data from 2002 to 2008 are used to determine these...

Prior literature documents that short sale activity clusters around mandated short sale position disclosures. We investigate two competing hypotheses for this finding in the UK market: herding- versus information-based trading. First, using an entropy-balanced matched sample of stocks, we find...
