We examine the trading behavior of investors facing a large number of firm-initiated stock trading suspension events during the Chinese stock market crisis in July 2015. Using account-level trading data from the Shanghai Stock Exchange, we find that investors with a higher fraction of holding value in suspension sell less (or purchase more) of non-suspended stocks. Consequently, non-suspended stocks whose shareholders have a high average account-level suspension fraction experience a short-term relative price appreciation. This evidence indicates that trading suspension can calm down investors and therefore help to stabilize the volatile market during crises.
