The information advantage of industry common owners and its spillover effect on stock price crash risk

Blockholding multiple firms within an industry generates an information advantage for institutional investors, who can better differentiate between the industry-wide and firm-specific nature of bad news released by peer firms and avoid selling on false spillover signals (i.e., “smart exit”). Empirically, we document that industry common ownership reduces future firm-level stock price crash risk. Our results can be explained by the attenuated spillover from industry peers' firm-specific bad news, as a complement to the monitoring effect that reduces the focal firm's hoarding of bad news. Our results suggest that the presence of industry common owners provides a stabilizing effect against stock price contagion.
