SK Hynix Plunges 10%, KOSPI Tumbles Over 5%

SK Hynix shares plunged about 10% and Samsung Electronics fell over 7%, dragging the KOSPI down more than 5%. Heavy foreign selling pushed valuations to record lows, with chip PER collapsing to 4x. Concerns over China's CXMT advancing in DRAM technology weighed on Korean memory giants. While short-term pressure is severe, the medium- to long-term impact may be limited if fundamentals remain intact.
