SK Hynix is trading 10.09% down, closing at KRW 1,443,000 on October 13, after reports that China’s CXMT plans to mass-produce denser 4F-square DRAM this year, raising competition concerns.

  • Foreign investors sold KRW 2.3613 trillion worth of SK Hynix shares.
  • Broader memory-chip weakness and severely contracted liquidity added pressure; reports point to sector-wide concerns, not a new SK Hynix-specific announcement.
