On the morning of the 8th, when a KOSPI buy-sidecar was activated, the status board at the dealing room of Hana Bank in Jung-gu, Seoul shows the KOSPI index up more than 5%. Reporter Moon Jae-won

On the 8th, following a ceasefire agreement between the United States and Iran, the KOSPI index surged, and a buy-sidecar was activated on the main stock market.

The Korea Exchange announced that at 9:06:02 a.m. that day, a buy-sidecar (a temporary suspension of program trading buy orders) was triggered on the main stock market. A buy-sidecar is a mechanism that halts program buying for five minutes to mitigate volatility. It is triggered when KOSPI200 futures remain 5% above the previous close for one minute. At the time of activation, KOSPI200 futures were trading at 875.45, up 6.23% from the previous session.

As of 9:04 a.m. that day, the KOSPI was trading at 5833.58, up 338.80 points (6.17%) from the previous session. The sharp recovery in risk appetite on the United States-Iran ceasefire agreement lifted large-cap stocks across the board.
