六、讲座内容

We investigate the causal effect of short selling on managers’ tone in firms’ earnings conference calls. Utilizing Regulation SHO, a regulation governing short-selling activities in the U.S. equity markets, we find that pilot firms with relaxed short-selling constraints use more negative tone. This effect is more pronounced for firms that are easier to short, have a manager with an incentive to manipulate the tone, and engage in less earnings management. Moreover, the negative relationship between tone and future earnings no longer holds for pilot firms after Reg SHO, suggesting that the tone in pilot stocks’ conference call better reflects their future earnings after the regulation. Overall, our findings suggest that short sellers play a role in external governance regarding tone management.
