KOSPI Soars, 'Buy Sidecar' Activated for 5 Minutes

As the KOSPI200 futures index surged, a 'buy sidecar' was triggered around 12:54 p.m. on the 10th, halting program buy orders for five minutes. This is a safety mechanism designed to temporarily suspend large-scale computer-driven buying to curb overheating during rapid price increases. According to the Korea Exchange, the sidecar was activated after the KOSPI200 futures index rose more than 5% from the previous trading day for one minute; at the time, the index had risen 5.13% to 1,240.15.

The KOSPI closed at 7,475.94, up 184.03 points (2.52%) from the previous trading day. During the session, it surpassed the 7,700 mark to reach a high of 7,704.93. In terms of capital flow at the exchange, institutions recorded a net buy of 1.1319 trillion won, while foreigners and individuals recorded net sales of 329.9 billion won and 772.8 billion won, respectively.

On the same day, the won-dollar exchange rate was recorded at 1,501.4 won.
