SK Hynix is trading at KRW 1,620,000, down 3.63%, as Korean semiconductor weakness coincided with a widening KOSPI decline. - A report cited investor reassessment of memory-chip growth, fading AI-trade momentum, profit-taking and capital outflows. - No new SK Hynix-specific announcement was identified. Earlier coverage described foreign and institutional selling on October 8, but that was not a confirmed October 12 catalyst.
