SK Hynix is trading 8.78% up at $1115 after Korean semiconductor stocks rallied on August 12, 2026.
- Samsung Electronics also advanced as foreign investors bought nearly 3 trillion won of South Korean equities, reflecting strengthened confidence in AI infrastructure demand.
- The move appears sector-driven rather than caused by a newly disclosed SK Hynix-specific event.
- Expectations for additional shareholder returns and SK Hynix’s NAND expansion plans provided supportive background.
