The KOSPI index plunged on the 3rd, triggering a "sell-sidecar." A sidecar is a measure that suspends the validity of sell quotes for program trading for five minutes. It is the first sidecar trigger in a month.

On the morning of the 3rd, the KOSPI index is displayed on the electronic board in the dealing room at the Hana Bank headquarters in Jung-gu, Seoul, the first trading day since the U.S. airstrike on Iran. The KOSPI opens at 6,165.15, down 78.98 points (1.26%) from the previous session, and KOSDAQ starts at 1,169.82, down 22.96 points (1.92%).
