    SK Hynix surges 20% on U.S. policy shift and Temasek investment

    Question

    SK Hynix surges 20% on U.S. policy shift and Temasek investment

    Direct answer

    The U.S. administration's preference for domestic or allied memory manufacturers (Micron, SK Hynix) over Chinese competitors creates a structural advantage for SK Hynix in the Apple supply chain. This is compounded by Elon Musk's recent comments that memory, not compute, is the primary bottleneck for agentic AI systems. Temasek's investment in both SK Hynix and Samsung signals a broader sovereign wealth rotation into the memory layer of the AI stack, which has historically been more cyclical and lower-margin than logic chips.
