Shares of SK Hynix climbed to an unprecedented level on Tuesday, propelled by surging demand for AI memory chips and the positive ripple effects from SanDisk’s imminent Nasdaq-100 entry.
The memory semiconductor manufacturer based in South Korea saw its Seoul-traded shares jump as much as 9% during the trading day, hitting 1,128,000 won. This represents an unprecedented peak in the company’s trading history.
The upward momentum followed a robust performance across U.S. markets on Monday. Tech-focused equities drove gains higher, sustained by ongoing optimism surrounding investments in artificial intelligence infrastructure.
SK Hynix stands as a leading provider of high-bandwidth memory (HBM), an essential element in AI chips manufactured by industry giants such as Nvidia. The appetite for HBM has been outpacing available supply, providing SK Hynix with considerable leverage on pricing.
Market participants have been favoring firms positioned within supply-limited segments of the AI semiconductor ecosystem — a category where SK Hynix holds a prominent position.
SanDisk’s Index Addition Provides Additional Momentum
SanDisk will enter the Nasdaq-100 index ahead of the April 20 market opening, taking the place of Atlassian. This announcement propelled SanDisk shares higher by 11.83% and boosted optimism throughout the memory and storage industry.
When companies join major indices, they typically see inflows from passive investment vehicles, which can elevate both the included stock and related companies within the sector. SK Hynix clearly benefited from this positive sentiment overflow.
Beyond market dynamics, the two firms share a strategic technology collaboration. SK Hynix and SanDisk are working together to create High Bandwidth Flash (HBF) — an emerging memory technology engineered to complement HBM in artificial intelligence systems.
HBF aims to address performance and capacity limitations in existing AI infrastructure, especially as data center operations and inference tasks continue expanding in scale.
Stronger Earnings Outlook and Pricing Power
The stock’s record-breaking trajectory is supported by improving business fundamentals beyond pure market enthusiasm. Korea Investment & Securities analysts increased their annual profit expectations for SK Hynix by 28%.
The revised forecast stems from better-than-anticipated pricing trends across both DRAM and NAND memory product lines.
SK Hynix provides critical components to major global technology corporations, including Apple and Nvidia. The company’s financial performance is directly linked to the expansion of worldwide AI infrastructure deployment.
The performance of U.S. technology equities continues to influence SK Hynix’s trajectory given these supply chain relationships.
The American depositary receipt equivalent of SK Hynix, listed under ticker HXSCL, rose more than 7% in the same trading period.
SanDisk concluded the session with an 11.83% gain on the Nasdaq exchange, primarily driven by the index inclusion announcement.
