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.

We propose a novel measure of upside asymmetry based on probability density function that utilizes information from the distribution of option returns. Our analysis of U.S. option data reveals a positive cross-sectional relationship between the upside asymmetry (RML) and subsequent option returns. This relationship cannot be explained by stock or option characteristics studied in previous literature and do not reverse in the following months. Additionally, the relationship is stronger among firms with higher costs of arbitrage. RML robustly predicts future realized and implied volatilities after controlling for historical volatility and lagged implied volatility.
