KORU is trading 2.71% higher on August 21, 2026, driven by South Korean semiconductor gains and shareholder-return plans.

  • SK Hynix gained 12.73% after announcing a 40 trillion won share buyback and cancellation plan; Samsung Electronics rose 9.49%.
  • The semiconductor-heavy KOSPI closed 0.88% higher, while Samsung’s reported shareholder-return package of up to 110 trillion won added support.
  • U.S. markets were only modestly higher, indicating a Korea-specific sector catalyst rather than broad risk-on trading.
