[Edaily Reporter PARK MIN ] At 10:05 a.m. on the 21st, the Korea Exchange (KRX) triggered a temporary suspension of sell-side program orders (sell-side “side car”) on the KOSDAQ market. This marks the 32nd side car triggered on the KOSDAQ market this year and the 14th sell-side side car.

At the time of activation, the KOSDAQ 150 futures price stood at 1,387.40, down 89.60 points (6.06%) from the previous day’s closing price, while the KOSDAQ 150 spot index fell 80.71 points (5.48%) to 1,391.11. At the same time, the KOSDAQ index stood at 800.86, down 4.76% from the previous trading day.

The KOSDAQ sell-side circuit breaker is triggered when the price of the KOSDAQ 150 futures contract with the highest trading volume on the previous day falls by 6% or more, and the underlying index drops by 3% or more, with both conditions persisting simultaneously for one minute.

Meanwhile, the KOSDAQ opened at 824.05, down 16.84 points (2.00%) from the previous trading day, and is extending its losses during the session. In particular, the top-market-cap stocks on the KOSDAQ—which span growth sectors such as secondary batteries, biotech, and robotics—are all trading lower as selling pressure spreads across the board.

As of 10:23 a.m., Alteogen Inc.(196170), the company with the largest market capitalization, is trading at 317,000 won, down 6.63% from the previous trading day. In addition, biotech stocks such as ABL Bio Inc.(298380)(-8.61%), Peptron, Inc.(087010)(-3.28%), PharmaResearch(214450)(-3.51%), and SAM CHUN DANG PHARM CO. LTD(000250)(-7.71%) are all showing weakness.

ECOPRO CO., LTD(086520) ECOPRO BM CO., LTD.(247540)also extended their losses, falling 5.90% and 7.19%, respectively, while the robotics stock also fell 6.26% to 442,000 won.
