South Korean shares opened sharply lower on Tuesday as renewed selling in semiconductor companies pushed the KOSPI down 161.03 points, or 2.4%, to 6,535.93 at the opening bell. The decline extended Monday’s losses and demonstrated the market’s continued sensitivity to changing expectations surrounding artificial intelligence investment.
Chipmakers lead the retreat
Samsung Electronics and SK hynix both fell heavily during early trading, with losses approaching 4% as the session developed. The weakness followed another decline in US semiconductor shares and growing investor concern about whether the extraordinary level of global AI expenditure can continue delivering sufficient returns.
The KOSPI briefly widened its decline to more than 3%, falling below the 6,500 level before recovering part of the initial loss.
Wall Street sets the tone
The negative opening followed a mixed session in New York. The Dow Jones Industrial Average gained 0.26%, but the technology-heavy Nasdaq Composite fell 0.76%.
Investors are now waiting for Nvidia’s quarterly results on Wednesday. The company’s performance and guidance for AI chip demand could have significant implications for South Korea, where Samsung and SK hynix are central suppliers to the global semiconductor industry.
Confidence remains fragile
Middle East tensions, high oil prices and uncertainty over US interest rates added to the cautious mood. Markets are also awaiting signals from Federal Reserve Chair Kevin Warsh at the Jackson Hole gathering later this week.
Seoul’s weak opening showed that confidence in the AI-driven semiconductor rally remains fragile despite the sector’s strong longer-term growth prospects.
