Kospi Crashes 8%, Triggers Circuit Breaker; SK Hynix Plunges Over 10%

The Kospi plunged 8%, triggering a circuit breaker, with SK Hynix shares tumbling over 10% and Samsung Electronics also falling sharply. The selloff is attributed to a hotter-than-expected US CPI print and a broad unwind of AI-related bets. As a Kospi heavyweight, SK Hynix's slump weighed heavily on the index; near-term pressure is evident, but a pullback could offer entry if AI demand holds.
