On October 21, the KOSPI index surged past the 5800 mark, recovering from the previous day's sharp decline. The index rose by over 4%, prompting the activation of a buying sidecar (a temporary halt on program buying orders) in the securities market.
According to the Korea Exchange, as of 11 a.m., the KOSPI was up 250.06 points (4.50%) at 5806.32. It opened at 5666.34, up 113.60 points (2.05%), and continued to expand its gains, fluctuating around a peak of 5816.43 during the session.
In the securities market, foreign investors purchased 319.3 billion won, while institutions bought 181.9 billion won. Individual investors sold 986.5 billion won.
The strong upward movement is attributed to a rebound from the KOSPI's sharp drop (-3.73%) the previous day and some gains in the New York stock market overnight, which led to increased buying interest in the domestic market.
The strong buying momentum triggered the activation of the sidecar. The Korea Exchange suspended the effectiveness of program buying orders for five minutes at 10:51:56 a.m. due to fluctuations in the KOSPI 200 futures index.
The buying sidecar is activated when the KOSPI 200 futures price rises more than 5% compared to the reference price and remains at that level for one minute. At the time of activation, the KOSPI 200 futures index was up 44.94 points (5.22%) at 904.84 compared to the previous day's closing price.
Samsung Electronics was trading at 227,000 won, up 7.33%, while SK Hynix rose 7.97% to 1,319,000 won.
Among other large-cap stocks, SK Square (6.75%), LG Energy Solution (0.72%), Samsung Electro-Mechanics (3.90%), and Samsung SDI (1.80%) also showed gains.
In contrast, LIG Defense and Aerospace fell nearly 15% after being sanctioned with a two-year bidding disqualification by the Defense Acquisition Program Administration due to bribery allegations related to past weapon development bids.
At the same time, the KOSDAQ index was up 14.93 points (1.90%) at 769.84, having opened at 793.40, up 11.43 points (1.46%).
In the KOSDAQ, foreign investors sold 92.6 billion won, while individuals bought 35.1 billion won and institutions purchased 53.7 billion won.
Among the top market cap stocks, Alteogen (3.25%), EcoPro (1.32%), EcoPro BM (3.61%), and Samchundang Pharm (2.44%) showed strong performance.
