SK Hynix is trading at KRW 1,269,000, up 3.76%, as stronger chip sentiment was supported by better-than-expected results from AI-server maker Super Micro Computer.
- On October 21, 2026, South Korean chip stocks rebounded after the prior session’s decline; strong U.S. earnings and lower international oil prices also supported sentiment.
- AI-spending concerns and competition from Chinese memory maker CXMT remain broader headwinds; the report is sector context, not an SK Hynix-specific announcement.
