Headline: "Kospi falls as foreign and institutional selling offsets a US tech rally led by Nvidia's 8.7% surge; Samsung Electronics and SK Hynix fell in unison" (Bloomingbit/CNBC, Aug 28, 2026). KODEX 200 dropped ~1.8% today even as US semis rallied hard on Nvidia's blowout and a US–UAE tech framework, so I expect Korean chips to play catch-up and the ETF to rebound at the next session.
