“…Theoretically, we build on the motivation, ability, and opportunity (MAO) framework (Heider 1958; Wang, Gupta, and Grewal 2017) to argue that short sellers (1) are motivated to exploit any informational advantage in the stock market (Diamond and Verrecchia 1987), (2) possess superior ability in detecting investment opportunities (e.g., Engelberg, Reed, and Ringgenberg 2012), and (3) use the opportunity to gain an informational advantage relative to average investors (e.g., Denev and Amen 2020). This approach is consistent with academic and business literature that documents a link between short selling and firm’s operations, strategy, and abnormal stock returns (Jia, Gao, and Julian 2020; Melloy and Rooney 2019; Shi, Connelly, and Cirik 2018) (see Table W2 of the Web Appendix). Our core argument is that an increase in customer satisfaction (dissatisfaction) lowers (elevates) short selling intensity in a firm’s stock, which affects abnormal stock returns.…”
