Samsung down 5%, SK Hynix slips 7%: is South Korea too dependent on AI boom?

Samsung Electronics and SK Hynix fell sharply on Friday as a selloff in US chip stocks spilled into South Korea, raising fresh questions about the country's heavy dependence on the artificial intelligence boom. The KOSPI opened 3.66% lower and later dropped as much as 5.7%, prompting the Korea Exchange to trigger a sell-side sidecar that briefly suspended programme trading.
