SK Hynix is trading 10.28% down at KRW 1,440,000 on October 13, 2026, amid concerns that CXMT’s progress on denser DRAM and planned year-end server-memory product could intensify competition and weigh on memory pricing.

  • The decline is part of a wider semiconductor selloff, with Korean chip shares falling as investors reassessed Chinese competition.
  • Sector context also identifies memory stocks as weak; no separate SK Hynix-specific announcement was found.
