Abstract: On August 21, 2000, the Singapore Exchange (SGX) adopted the call market method to open and close the market while the remainder of the day's trading continued to rely on the continuous auction method. The call method significantly improved the price discovery process and market quality. A positive spillover effect is observed from the opening and closing calls. Day-end price manipulation also declined after the introduction of the call market method. However, the beneficial impact from the call market method is asymmetric, benefiting liquid stocks more than illiquid stocks.
