Following the announcement of mutual tariff exemptions by the Donald Trump administration, the domestic stock market surged, triggering a temporary halt on buy orders (buy sidecar) in the KOSDAQ market after the KOSPI market.
The Korea Exchange announced at 10:46 a.m. on the 10th that it would implement a buy sidecar for five minutes due to fluctuations in KOSDAQ 150 futures prices and the KOSDAQ 150 index.
At that time, the KOSDAQ 150 futures price had risen by 6.08% compared to the previous day, and the KOSDAQ 150 index had also increased by 5.83%. The buy sidecar in the KOSDAQ is a mechanism designed to enhance market stability by halting program buy orders for five minutes. It is applied when the KOSDAQ 150 futures price and the KOSDAQ 150 index rise by more than 6% and 3%, respectively, for over one minute compared to the previous day's closing price.
The activation of the sidecar in the KOSDAQ market marked the first time in eight months since the so-called 'Black Monday' on August 6 of last year.
A buy sidecar was also triggered at 9:06 a.m. in the KOSPI market on the same day. This was the first occurrence of a buy sidecar in the KOSPI market since August 6 of last year.
