Due to the rapid revolution in trading strategies, market environment is very different from the past, and the market intervention in national stock exchanges has been taken seriously again . However, very few studies discussed the rule-based trading suspension for individual stocks in the past, and most of them only focused on the impact of trading halt on market performance. For this reason, this study in addition to measures impact of market performance, another major analysis focuses on the differences between individual and institutional investors order behavior under different halt conditions. We try to understand whether the current halt mechanism achieves the purposes of reducing the information asymmetry and the abnormal volatility. The market performence empirical results show that transitory trading halt can reduce the overreaction of re-opening, but the halt of follow-up 5 minutes of the liquidity decreased, and volatility increased. Next, we find the individual investors order aggressive tend to be conservative in the period of suspension. In contrast, Institutional investor behavior will tend to be more positive with higher information asymmetry and will not be affected by the trading halt. Moreover, from follow-up 20 minutes individual-institutional transaction VWAP ratio, we find that the trading halt will improve the performance of individual investors transactions.
