The Korea Exchange (KRX) launched its aftermarket on September 14, allowing investors to continue trading in high-volume stocks such as photonics and light electronics. With real-time trading available after regular market hours, the domestic stock market will operate until 8 p.m. starting today.
As of 4:50 p.m., the top traded stock on the KOSPI was photonics, with approximately 28.92 million shares changing hands. Photonics was trading at 10,270 won, up 30.00% from the previous trading day. Samsung Electronics followed with about 16.71 million shares traded, while SM Biopharma, HMM, and Hyundai Pharmaceutical had around 10.44 million, 9.82 million, and 8.53 million shares traded, respectively.
On the KOSDAQ, light electronics led with about 76.26 million shares traded. It was followed by Dream Security with approximately 36.99 million shares, Xgate with about 16.23 million shares, Samik Pharmaceutical with around 15.09 million shares, and Korea BNC with about 13.94 million shares. Notably, Samik Pharmaceutical saw a rise of over 20%, while Korea BNC and light electronics both increased by more than 10%, indicating significant volatility.
The aftermarket began immediately after the regular market closed sharply lower. The KOSPI ended down 3.26% at 6,684.37, while the KOSDAQ fell 1.69% to 806.79. In the KOSPI market, foreign and institutional investors sold a net 3.29 trillion won and 1.17 trillion won, respectively, while individual investors bought a net 2.97 trillion won.
The KRX aftermarket operates from 4 p.m. to 8 p.m. Unlike the previous single-price trading, this new system allows for immediate execution of trades when buy and sell orders match, similar to regular market trading. This change enables investors to respond in real-time to market conditions and stock-specific issues even after the regular trading hours.
Additionally, the overlap in operating hours between the alternative exchange Next Trade (NXT) and the KRX aftermarket has intensified competition among multiple markets after the close. For investors, this means extended trading hours and a variety of markets to consider for order execution based on price and liquidity.
