SK Hynix is trading at KRW 1,495,000, down 10.37%, after broad AI-memory selling intensified across Korean chip stocks.

  • Weak guidance from SanDisk and Western Digital revived concerns about memory demand, valuation, and AI-capital-spending returns.
  • Heavy foreign selling pushed Korea’s KOSPI sharply lower, while peers including Samsung Electronics also declined.
  • The move appears sector-driven rather than caused by a fresh SK Hynix-specific announcement.
