    SK Hynix surges on U.S. opposition to Chinese memory chips in Apple supply chain

    Question

    SK Hynix surges on U.S. opposition to Chinese memory chips in Apple supply chain

    Direct answer

    The Trump Administration's stance against Chinese memory chips marks a significant escalation in tech decoupling. By targeting Apple's supply chain, the policy forces a shift toward higher-cost or capacity-constrained alternatives in South Korea and the U.S. SK Hynix's 20.6% weekly gain reflects both this policy tailwind and new investment from Singapore's Temasek.
