Disclosure Tone and Shareholder Litigation
研究了公司披露中的乐观语气是否增加股东诉讼风险，发现原告更倾向于起诉那些语气过于乐观的公司，且内部人异常卖出会加剧这一风险。
ABSTRACT We examine the relation between disclosure tone and shareholder litigation to determine whether managers' use of optimistic language increases litigation risk. Using both general-purpose and context-specific text dictionaries to quantify tone, we find that plaintiffs target more optimistic statements in their lawsuits and that sued firms' earnings announcements are unusually optimistic relative to other firms experiencing similar economic circumstances. These findings are consistent with optimistic language increasing litigation risk. In addition, we find incrementally greater litigation risk when managers are both unusually optimistic and engage in abnormal selling. This finding suggests that firms can mitigate litigation risk by ensuring that optimistic statements are not contradicted by insider selling. Finally, we find that insider selling is associated with litigation risk only when contemporaneous disclosures are unusually optimistic. JEL Classifications: G38; K22; M41; M48.
