Samsung SDI is trading at KRW 511,000, down 4.13%, amid weakness in Korean secondary-battery shares; no clear company-specific catalyst surfaced.

  • Samsung SDI was also reported lower in early trading.
  • Rising U.S. Treasury yields, higher oil prices and foreign selling weighed on South Korean equities.
  • The prior-day activist proposal concerned Samsung affiliates’ S-1 stake, not an announced Samsung SDI operating or earnings change.
