SK Hynix shares climbed more than 6% on Monday, June 15.
The rally followed the company's leadership in high-bandwidth memory (HBM) chips for AI accelerators.
A worldwide shortage of memory chips further supported the stock's performance.
Broader Asian markets surged after the United States and Iran announced a peace agreement.
Analysts cite sustained AI demand and an accelerated timeline for HBM4E memory samples as growth drivers.
