As global semiconductor stocks rebound across the board, "sidecar" trading halts—which temporarily suspend the execution of program buy orders—were triggered sequentially on both the KOSPI and KOSDAQ markets today (June 9).
The Korea Exchange announced that it suspended the effect of program buy orders on the KOSPI market for five minutes starting at 9:12:52 a.m. today, following a surge in the KOSPI 200 futures index.
At the time of the trigger, the KOSPI 200 futures index stood at 1,239.05, up 60.80 points from the previous day's closing price.
A KOSPI sidecar is triggered when the KOSPI 200 futures price rises by 5% or more from the reference price and sustains that level for one minute.
Subsequently, at 9:28:14 a.m., a sidecar was also triggered on the KOSDAQ market, suspending program buy orders for five minutes.
At that time, the KOSDAQ 150 futures price was 1,676.30, up 104.10 points from the previous day's close, while the KOSDAQ 150 spot index was 1,676.69, up 90.36 points.
A KOSDAQ sidecar is triggered when the KOSDAQ 150 futures price rises by 6% or more and the KOSDAQ 150 index rises by 3% or more from the previous trading day's closing value, with both conditions sustained for one minute.
Yesterday, widespread panic selling led to significant index drops, resulting in the activation of circuit breakers and sell-side sidecars in both markets. However, a sharp rebound occurred just one day later, triggering buy-side sidecars.
This marks the first time since May 21 that buy-side sidecars have been triggered simultaneously on both the KOSPI and KOSDAQ markets.
