KOSDAQ Surges Over 3%, Buy-Side Sidecar Triggered

The KOSDAQ index surged by more than 3%, triggering a buy-side sidecar (temporary suspension of program buy orders).

As of 2:17 p.m. on June 11, 2026, the KOSDAQ index stood at 988.22, up 36.59 points (3.84%) from the previous trading day. The KOSDAQ index, which opened lower at 937.17, has since reversed course and is continuing its upward trend.

As military tensions between the United States and Iran escalated again, the New York stock market closed down across the board, and the domestic KOSPI also started the day with a decline of more than 2%. On the 11th, an employee at Hana Bank's head office dealing room in Jung-gu, Seoul, monitored the stock market and exchange rates. On that day, the KOSPI opened at 7,509.62, down 221.20 points (2.86%) compared to the previous trading day. June 11, 2026 Photo by Cho Yongjun

Due to strong buying, a buy-side sidecar was triggered at 1:58 p.m. on the same day. In the KOSDAQ market, when the KOSDAQ 150 futures price rises by 6% or more from the reference price and the KOSDAQ 150 index increases by 3% or more from the previous trading day's closing value, and these conditions persist simultaneously for one minute, the sidecar is activated, suspending the effectiveness of program buy orders for five minutes.

This is the first time in two days that a buy-side sidecar has been triggered in the KOSDAQ market since June 9.
