South Korean shares fall sharply as investors sell technology and AI-linked chipmakers, dragging regional markets lower. The KOSPI drops by about 6% in one session, with some outlets reporting deeper declines toward or beyond the 20% retracement from recent peaks, and trading halts triggered during the rout.

The sell-off spreads from heavyweights including SK Hynix and Samsung Electronics, with declines also seen among related technology and semiconductor names in Japan and across Asia. Several reports link the move to “AI fatigue” or concerns that valuations for chip stocks have run ahead of fundamentals, especially given expectations of continued high spending on AI infrastructure. Some outlets also note that investors rotate toward cheaper markets, including parts of China’s technology sector, as they seek better value.

In addition to chip-specific sentiment, macro factors appear alongside the equity unwind. Business Standard cites a Bank of Korea interest rate hike as a contributor to the KOSPI’s large drop, aimed at curbing inflationary pressures related to the Iran war, while other reports emphasize geopolitical risk around US-Iran tensions and the broader external headwinds facing markets.

Overall, outlets agree the moves are driven primarily by renewed weakness in semiconductor and AI-linked equities, with timing and depth varying by market and report.
