    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 has signaled a clear preference for Apple to source memory components from non-Chinese entities, specifically targeting U.S. firms or those in allied nations like South Korea. This has led to a significant re-rating of SK Hynix, which also saw a 20.6% weekly gain following a positive market share report from Counterpoint Research. The move reinforces the 'China Plus One' strategy and suggests that memory, rather than just compute, is becoming a focal point of trade-related semiconductor restrictions.
