The KOSPI 200 futures index surged nearly 6% at the start of the market on the 10th, triggering a buy sidecar in the securities market.
The Korea Exchange announced that a temporary suspension of program buy orders in the securities market was triggered at 9:06 a.m. on that day.
A sidecar is triggered when the KOSPI 200 futures price fluctuates more than 5% compared to the previous day's closing price and this price lasts for one minute, during which program trading orders are suspended for five minutes.
On that day, the KOSPI 200 futures recorded 323.45, up 18.80 points (6.17%) from the previous trading day. This is interpreted as a result of foreign investors purchasing a net 395.8 billion won.
On the 7th, the KOSPI index fell sharply, triggering a sell sidecar. Previously, on August 5th of last year, during the global stock market crash known as Black Monday, a sell sidecar was activated, and the following day, the 6th, a buy sidecar was triggered due to a sharp rise in the index.
