    SK Hynix Surges on U.S. Policy Shift Against Chinese Memory Chips

    Question

    SK Hynix Surges on U.S. Policy Shift Against Chinese Memory Chips

    Direct answer

    The Trump Administration's stance against Chinese memory chips in the Apple supply chain creates a structural tailwind for SK Hynix and Micron. This policy shift is part of a broader effort to secure technology supply chains within allied nations. SK Hynix's 20.6% weekly gain reflects both this policy tailwind and new capital inflows from Temasek, suggesting a re-rating of the memory sector based on geopolitical alignment.
