    US Policy Shift Favors Allied Memory Makers Over Chinese Suppliers

    Question

    US Policy Shift Favors Allied Memory Makers Over Chinese Suppliers

    Direct answer

    The Trump Administration's stance against Chinese memory components in the Apple supply chain marks a significant escalation in tech trade policy. This shift directly benefits South Korean and US-based memory producers who can absorb the displaced volume. SK Hynix has already seen a 20.6% weekly surge, significantly outperforming the broader Nasdaq, as market participants price in both the policy tailwind and new institutional backing from Temasek.
