[Financial News] KOSPI closed in the 8,100 range after plunging more than 5% as foreign investors took profits amid a "Broadcom shock."
\r\nOn the 5th, KOSPI ended trading at 8,160.59, down 478.82 points, or 5.54%, from the previous session.
The index fell sharply right after the opening bell, triggering a program-trading sell-side circuit breaker. At one point during the session, it dropped to 8,038.10, coming close to the 8,000 level.
Foreign investors extended their selling streak to 20 consecutive trading days, dragging the index lower. They sold a net 352.13 billion won, while institutions posted net sales of 94.27 billion won. Retail investors were net buyers of 422.38 billion won.
Most large-cap stocks fell, including Samsung Electronics Co., Ltd. (-6.40%), SK hynix (-9.92%), SK Square (-7.57%), LG Energy Solution (-1.90%), Samsung Life Insurance (-5.82%), and Samsung C&T Corporation (-13.93%).
On the other hand, Samsung Electro-Mechanics (2.39%), HD Hyundai Heavy Industries (2.00%), KB Financial Group (4.51%), and Shinhan Financial Group Co., Ltd. (7.39%) rose.
By sector, textiles and apparel, as well as food and tobacco, were strong, while distribution, electric and electronic equipment, manufacturing, insurance, machinery and equipment, medical and precision instruments, IT services, construction, metals, and chemicals declined.
Jin-hyuk Kang, a researcher at Shinhan Investment Corp., analyzed that semiconductor stocks fell due to disappointment over Broadcom Inc.'s guidance for artificial intelligence chip sales and the Micron CEO's stock sale. He added that capital outflows ahead of SpaceX's planned listing also affected the index and the won-dollar exchange rate.
Meanwhile, KOSDAQ closed at 1,002.44, down 47.29 points, or 4.50%, from the previous session. The index briefly fell to the 990 range during the day, slipping below 1,000 for the first time in about three months, but it recovered part of its losses.
