Abstract

This study investigates the relationship between order aggressiveness and the distance between stock market prices and price limits in order to shed some light on the ‘heating’ and ‘cooling-off’ effects of these limits. Using intraday data on the Taiwan Stock Exchange (TSE), in conjunction with piecewise ordered probit regressions, we find that a significant ‘inverted-N’ (‘N’) shape pattern is discernible on the sell (buy) side of the relationship between order aggressiveness and price distance, which is consistent with the heating effect of upper (lower) price limits, as well as a cooling-off effect of lower (upper) price limits for market sellers (buyers). This study is the first to analyze changes of market participants’ order aggressiveness when approaching price limits. Our findings offer clear indications to policymakers that price limits could counteract irrational stock markets.
