讲座主题:Shorting Activity and Stock Return Predictability: Evidence from an Information Shock  

 

摘要:Employing the international equity lending markets as a laboratory to capture investors’ private information flow, we show that the ability of shorting to predict negative future stock returns drops after the public information shock of a mandatory accounting change, thus reducing short-sellers’ profitability. We also show that shorting profitability drops due to a decrease in investors’ divergence of opinion around the public information shock. These results imply that the introduction of a mandatory accounting change that increases public information flow can crowd out short-sellers’ use of private information, consistent with a substitutional relation between public and private information.
