The Korea Exchange (KRX) on Wednesday activated a trading halt on the main bourse due to a sharp rally led by tech firms.
A buy-side order in the Korea Composite Stock Price Index (KOSPI) futures was suspended for five minutes at around 9:06 a.m., according to the KRX.
The benchmark KOSPI opened at 8,242.12, up 194.61 points, or 2.42 percent, and further extended gains.
A buy-side sidecar is triggered when the KOSPI 200 Futures index increases 5 percent or more for at least one minute.
