SK Hynix is trading at KRW 1,439,000, down 5.70% on October 30 after Samsung results weighed on memory-chip stocks.

  • Samsung’s quarterly chip profit rose sharply, but results fell short of high expectations and its outlook was less optimistic than SK Hynix’s.
  • Reuters cited concerns about the outlook; Korean coverage also noted caution about the sustainability of AI spending.
  • The pullback followed SK Hynix’s strong prior-session rally and appears sector-led, not prompted by a new negative company announcement.
