This study empirically investigates transitory and asymmetric properties in price limits at the Kcrean Stock Exchange. Even though there has been much empirical research for or against price limits in the literature, we point our two flaws to be remedied. Flaws to be remedied. First, most research has used inter-day data rather than intra-day data, which hag resulted in ignoring the underlying forces to determine prices. Second, they have assumed that the effects of price limits are symmetric across upper price limits and lower price limits. The asymmetric effect would not be detected without using using the intra-day data. Specifically, the adverse effects of price limits such as trading interference are stronger when prices hit upper limits rather than lower limits, Having observed the asymmetric and transitory features of price limits, we suggest that the magnitude of the upper limit should be bigger than that of the lower limit in order to strike the balance between the market efficiency enhancement and volatility reduction.
