Meanwhile, to calculate trading performance, the authors used cumulative return calculation. By using the daily transaction data of domestic and foreign investor, this study proved that herding behavior is stronger in foreign investors than domestic investors in both suspension periods. The investment performance of foreign investors is better than domestic investors. Domestic investors have the information-based model as an investing pattern, while foreign investors have the value-investing model before suspension and information-based model after suspension.
