On June 1, the KOSPI surged, triggering a buy-side sidecar (temporary suspension of program buy orders) for the first time in three trading days.

The Korea Exchange announced that at 11:30:32 a.m. on this day, due to volatility in the KOSPI 200 futures index, the effectiveness of program buy orders was suspended for five minutes.

At the time the sidecar was triggered, the KOSPI 200 futures index stood at 1,417.90, up 67.90 points (5.02%) from the previous closing price.

This is the first time the KOSPI buy-side sidecar has been triggered in three trading days since May 27.

The KOSPI broke through the 8,800-point mark on this day, setting a new all-time high.
