RT Journal Article SR Electronic T1 When Short Sellers and Corporate Insiders Agree on Stock Pricing JF The Journal of Portfolio Management FD Institutional Investor Journals SP jpm.2019.1.084 DO 10.3905/jpm.2019.1.084 A1 Chune Young Chung A1 Hong Kee Sul A1 Kainan Wang YR 2019 UL https://pm-research.com/content/early/2019/03/05/jpm.2019.1.084.abstract AB The authors propose a strategy that uses trading information of both short sellers and corporate insiders. They find that the strategy earns statistically significant and economically meaningful risk-adjusted returns for at least one year, stemming mainly from the information asymmetry between informed and uninformed investors. Based on this finding, they then show that the strategy works best in high-information-asymmetry environments and during economic expansion periods. The results have important implications for investment practitioners. Investors interested in high-information-asymmetry firms can refer to the information on short interest and insider demand when making investment decisions.
