The KOSDAQ Market Headquarters announced on the 29th at 10:56:07 a.m. that it had triggered a "sidecar," suspending the effectiveness of program sell orders on the KOSDAQ market for five minutes.

This measure was taken because the requirements for triggering the mechanism were met as the KOSDAQ 150 futures price and the KOSDAQ 150 spot index plunged. The KOSDAQ 150 futures price recorded 1,121.20 points, down 74.30 points (-6.21%) from the previous day's closing price of 1,195.50 points. The KOSDAQ 150 spot index also stood at 1,115.32 points, down 75.05 points (-6.30%) from the previous day's close of 1,190.37 points.

The Korea Exchange implemented the sidecar, which suspends the effectiveness of program sell orders for the next five minutes in response to index volatility, in accordance with Article 13 of the KOSDAQ Market Business Regulations and Article 14 of its Enforcement Detailed Rules.

Earlier that same morning, a sell-side sidecar was also triggered in the KOSPI market.
