A sell-side sidecar was triggered on the KOSPI on the 19th after the index fell sharply.


According to the Korea Exchange, program sell orders were temporarily suspended on the KOSPI market at 9:06 a.m. that day.


A KOSPI sell-side sidecar is triggered when KOSPI 200 futures prices fall 5% or more below the base price and sustain that level for one minute.


Meanwhile, the KOSPI is falling sharply that day, led by large-cap chip stocks. As of 9:25 a.m., Samsung Electronics was trading at 248,250 won, down 7.54% from the previous session, while SK Hynix was trading at 1,505,500 won, down 9.42%.
