SK Hynix, Korean Chip Stocks Plunge as US Selloff Spills Over

SK Hynix tumbled intraday, trading about 20.6% below its 20-period moving average, as a US AI chip selloff spilled into Korea. Samsung fell in tandem, KOSPI opened down about 3%, foreign outflows topped $100bn and an ETF shorting Hynix gained 64%. The hit is near-term and flow-driven rather than a fundamental deterioration.
