Stocks Close Lower as Investors Search for Direction Amid AI Sector Uncertainties

On November 9, 2026, Seoul's stock market closed lower as investors grappled with uncertainties in the artificial intelligence (AI) sector. The benchmark Korea Composite Stock Price Index (KOSPI) fell by 40.84 points, or 0.81%, ending at 5,018.85.

Investors were particularly concerned about an internal probe at Nvidia Corp. following allegations involving its CEO, Jensen Huang, and a suspected Chinese spy. This scandal added to the existing volatility in the market, causing many to reevaluate their positions.

Despite this, some sectors showed resilience. Semiconductors, for instance, experienced a slight recovery as fears regarding AI data centers eased. Samsung Electronics rose by 0.64%, while SK Hynix gained 0.35%. However, other major companies like LG Energy Solution and Hyundai Motor saw declines of 5.78% and 2.86%, respectively.

The trading volume was relatively low, with 231.8 million shares exchanged, amounting to 17.26 trillion won ($12.8 billion). Foreign and retail investors were net sellers, offloading a combined 1.18 trillion won, while institutional investors purchased a net 717.1 billion won.

As the market navigates these uncertainties, analysts suggest that investors are cautiously searching for direction, especially in the tech-heavy sectors.
