- The KOSPI closed at 5,018.85 on November 9, down 0.81% from Friday's close.
- Foreign and retail selling outweighed institutional buying, while semiconductor shares recovered modestly.
- AI-sector uncertainty and a fresh Nvidia-related investigation kept investors cautious.
The KOSPI ended Monday's session at 5,018.85, down 40.84 points, or 0.81%, from the previous session. The closing figures and market background were reported by Yonhap News Agency. The decline followed Friday's close at 5,059.69, which was also recorded in the index's previous coverage.
Rebound loses momentum
Seoul shares traded erratically after the market opened. Semiconductor stocks recovered part of their recent losses, but the broader index could not sustain its advance. Most large-cap stocks ended lower, leaving 527 decliners against 340 advancers. Trading volume was 231.8 million shares, with turnover of 17.26 trillion won.
Foreign investors and retail investors sold a combined net 1.18 trillion won in KOSPI shares, while institutional investors bought a net 717.1 billion won. The flow data and the session's breadth indicate that institutional bargain hunting was not sufficient to offset broader selling pressure.
Semiconductors provide limited support
Samsung Electronics rose 0.64% to 189,900 won, and SK hynix gained 0.35% to 1,136,000 won. Their gains provided support after a sharp sector sell-off in the previous week, but they were not enough to lift the overall index.
Weakness was more pronounced in several other major sectors. LG Energy Solution fell 5.78% to 318,000 won, Hyundai Motor declined 2.86% to 271,500 won, and Hanwha Aerospace dropped 3.18% to 639,000 won. These individual-stock moves are components of the market's performance, not a separate index measure.
AI uncertainty remains in focus
According to Yonhap, investors were weighing uncertainty surrounding the outlook for AI data-center investment and a fresh controversy involving Nvidia Chief Executive Jensen Huang. The report said semiconductor stocks recovered as some concerns following the US midterm elections eased, while the Nvidia-related investigation created renewed jitters. The KOSPI's decline therefore reflected a mixed session rather than a uniform retreat in technology shares.
The Korean won strengthened to 1,347.1 won per US dollar at 3:30 p.m. local time, according to Yonhap. Investors will continue to watch developments in AI demand, semiconductor earnings and foreign fund flows for direction after the latest volatile session.
