SK Hynix shares advanced 2.8% to ₩1,736,000 on Thursday, lifting South Korea’s KOSPI index by 2% and outpacing rival Samsung Electronics, which rose 2.2%. The gains followed Nvidia’s fiscal second-quarter results, which highlighted sustained demand for advanced memory components used in artificial intelligence accelerators.
Nvidia reported quarterly revenue of $96.2 billion, a 106% increase from the prior year, driven by a 117% surge in Data Center revenue to $89 billion. The company also raised its third-quarter revenue guidance to approximately $108 billion, exceeding market expectations of roughly $104 billion.
SK Hynix, a primary supplier of High Bandwidth Memory chips to Nvidia, posted record second-quarter revenue of ₩79.3 trillion with an operating margin of 76%. The company also announced a ₩40 trillion share buyback program on August 19, further supporting investor confidence in its near-term outlook.
Analysts attributed the broad semiconductor rally to Nvidia’s earnings, which reinforced expectations for continued strength in AI-related memory demand. The KOSPI’s advance extended gains across South Korea’s tech-heavy index, with SK Hynix leading advancers amid the sector-wide momentum.
