KOSPI plunges over 10% amid semiconductor sell-off and AI investment concerns.
The KOSPI index experienced a significant decline of over 10% on July 28, 2026, primarily driven by a massive sell-off in semiconductor stocks. This downturn was further exacerbated by investor apprehensions regarding the sustainability of substantial investments in artificial intelligence (AI).
Key points
- Semiconductor Sell-Off: SK Hynix and Samsung Electronics, which together constitute more than half of the KOSPI's market capitalization, saw their shares plummet by 14.4% and 13.6%, respectively.
- AI Investment Concerns: Investors are increasingly worried about the viability of massive AI infrastructure spending, leading to a reevaluation of valuations in the tech sector.
- Chinese Competition: The rapid advancements of Chinese semiconductor companies, such as the debut of ChangXin Memory Technologies (CXMT), have intensified competition, further pressuring South Korean chipmakers.
- Market Volatility: The KOSPI's sharp decline triggered trading curbs, including a 20-minute halt, underscoring the heightened market volatility.
