KOSPI Circuit Breaker Triggered Following Over 8% Plunge; Sidecars Also Activated

As the domestic stock market faces a sharp correction, the KOSPI plunged more than 8% during trading today, June 23, triggering a "circuit breaker" to temporarily halt trading.
The Korea Exchange announced that trading on the KOSPI market was suspended for 20 minutes starting at 2:33:43 p.m. today.
This action was taken after the KOSPI index fell by more than 8% from the previous day's closing price and remained at that level for one minute, meeting the criteria for a circuit breaker.
Consequently, trading for all stocks listed on the KOSPI market was temporarily halted, along with trading in stock-related futures and options markets.
The circuit breaker was lifted 20 minutes later, at approximately 2:53 p.m.
At the time the circuit breaker was triggered, the KOSPI was at 8,378.25, down 736.30 points (8.07%) from the previous trading day.
This marks the fourth time a KOSPI circuit breaker has been triggered this year and the 10th time in history.
Earlier this year, circuit breakers were triggered in the KOSPI market on March 4 and March 9 due to the aftermath of the war between the United States and Iran, and again on June 8 due to the impact of a global semiconductor stock correction.
In the KOSPI market, a program sell order sidecar was also activated at 11:40:44 a.m. due to volatility in the KOSPI 200 futures index, suspending the effect of program sell orders for five minutes.
At the time of activation, the KOSPI 200 futures index was at 1,407.54, down 76.06 points (5.12%) from the previous day's closing price.
The KOSDAQ index is also showing a sharp decline. Similar to the KOSPI market, a sell sidecar was triggered at approximately 9:06:02 a.m. today, suspending the effect of program sell orders for five minutes.
The KOSDAQ index has continued its downward trend since then and is currently at 903.05, down 6.75% from the previous session.
This is the first time in 15 days, since June 8, that sell sidecars have been triggered simultaneously in both the KOSPI and KOSDAQ markets.
