Using a unique list of 528 fake state-owned enterprises (SOEs) exposed in China, we examine whether and how investors react to the government’s property rights protection actions. Our results show that real SOEs with more subsidiaries, pyramid layers, and popularity are more likely to be targeted by wrongdoers. We find that when fake SOEs were exposed, it caused a significant increase in the stock prices of listed central SOEs controlled by the State Council. Further analysis shows that the stock price rise is driven by both the cash flow and risk effects. We also find that the value impact of the crackdown is more pronounced for listed central SOEs with less media coverage, located in weaker legal protection regions, and facing more competition. Overall, our findings provide empirical support for the effectiveness of exposure, as a non-litigation channel of property rights protection, in enhancing firm value.
