Using US‐listed Chinese firms as the setting, this paper studies a novel channel through which investors can acquire information about firms’ financial reporting quality, that is, the reports published voluntarily by short sellers. I find that short sellers tend to target firms that have financial reporting red flags and that exhibit ‘good’ operating performance and stock valuations. Targeted firms experience an average three‐day cumulative abnormal return (CAR) of −6.4%, and −13.6% for initial coverage of the firm, and the CARs are more negative when the reports allege more severe misconduct of the firms. Non‐targeted firms also experience losses in value following short seller reports, especially when they hire the same non‐Big 4 auditors as targeted firms and when their earnings quality is poor. In comparison, analysts fail to perform proper due diligence and are much less effective than short sellers in exposing misreporting risk in Chinese firms.
