Abstract-One type of circuit breaker is price limit, which is used in future markets and other stock exchanges of emerging markets in order to prevent markets from excessive volatility, market controlling, crash occurrence and to enhance the market stability. The range of price limits in most of stock exchanges have changed with specific reasons. Researchers have different opinions about the effects of applying the price limit system, and the positive or negative effects that are caused by using this system are not yet confirmed in conducted researches definitely. This paper examines the effects of price limits on Bursa Malaysia (previously known as Kuala Lumpur Stock Exchange, KLSE) before and after the 2007-2008 crisis by testing the volatility spillover and trading interference hypotheses. The statistical results of this study do not support the tested hypotheses since smaller volatility is experienced by stockshit category during postlimit days compared to other categories. In addition, the trading volume of stockshit does not increase after price-limit-hits that it leads to understanding the concept that this system does not prevent rational trading on price-limit-hit day.
