- SK Hynix climbed as much as 9% to reach a historic peak of 1,128,000 won during Tuesday trading.
- Strong optimism around AI infrastructure and a broader technology sector rally on Wall Street fueled the advance.
- SanDisk will enter the Nasdaq-100 index on April 20, taking Atlassian’s place, which lifted sentiment throughout memory chip companies.
- The two companies are collaborating on High Bandwidth Flash (HBF), an innovative memory solution for AI applications.
- Korea Investment & Securities boosted their annual profit projection for SK Hynix by 28%.
SK Hynix shares reached an unprecedented high on Tuesday, propelled by surging AI chip requirements and the upcoming addition of SanDisk to the Nasdaq-100 index — creating a powerful dual catalyst.
The Seoul-listed shares of the South Korean memory manufacturer jumped as much as 9% during the session, touching 1,128,000 won. This represents an unprecedented valuation milestone for the semiconductor producer.
The advance followed a robust performance on Wall Street the previous day. Tech equities spearheaded a widespread market rally, driven by persistent optimism surrounding AI infrastructure investments.
SK Hynix serves as a leading provider of high-bandwidth memory (HBM), a critical element in AI processors manufactured by industry leaders such as Nvidia. HBM demand has outpaced available supply, providing SK Hynix with substantial pricing leverage.
Market participants have favored companies positioned within supply-constrained segments of the AI semiconductor ecosystem — a category where SK Hynix maintains a prominent position.
SanDisk’s Index Entry Provides Additional Momentum
SanDisk will become a Nasdaq-100 component prior to market opening on April 20, taking the position currently held by Atlassian. This development drove SanDisk shares up 11.83% and strengthened investor confidence across memory and storage companies.
Index additions generally trigger passive investment fund purchases, creating positive momentum for both the entering stock and associated companies within the same industry. SK Hynix clearly benefited from this cross-sector optimism.
The two corporations are connected through an active technological collaboration. SK Hynix and SanDisk are working together to create High Bandwidth Flash (HBF) — an advanced memory architecture engineered to complement HBM in AI platforms.
HBF aims to address performance and capacity limitations in existing AI hardware, especially as data center and inference requirements continue expanding.
Improved Forecasts and Strong Pricing Dynamics
The historic rally reflects strengthening business fundamentals alongside positive market psychology. Korea Investment & Securities increased their annual earnings projection for SK Hynix by 28%.
The revision stemmed from pricing performance exceeding expectations for both DRAM and NAND memory offerings.
SK Hynix provides essential components to major global technology corporations, including Apple and Nvidia. The company’s trajectory remains closely linked to the expansion of worldwide AI infrastructure.
U.S. technology equities have continued supporting SK Hynix’s momentum through these supply partnerships.
The American-listed version of SK Hynix, trading under ticker HXSCL, rose more than 7% during the corresponding session.
SanDisk finished the day up 11.83% on the Nasdaq, with the index inclusion announcement serving as the primary driver for the movement.
