- Positive sentiment from Wall Street’s tech sector rally and robust AI infrastructure optimism fueled the advance.
- SanDisk’s scheduled entry into the Nasdaq-100 index on April 20, taking Atlassian’s spot, lifted memory sector confidence.

Shares of SK Hynix reached unprecedented levels on Tuesday, buoyed by surging demand for AI memory chips and positive news surrounding SanDisk’s imminent addition to a major tech index.
The memory chip manufacturer based in South Korea saw its Seoul-traded shares climb as high as 9% during the trading session, touching 1,128,000 won — a new peak for the semiconductor company.
The rally built upon momentum from Monday’s trading in the United States, where technology equities dominated gains. Investors remained enthusiastic about ongoing capital deployment in artificial intelligence infrastructure.
SK Hynix ranks among the leading manufacturers of high-bandwidth memory (HBM), a critical component powering AI accelerators produced by firms such as Nvidia. The market for HBM has experienced demand outpacing available supply, enabling SK Hynix to command favorable pricing.
Market participants have consistently favored companies positioned within supply-constrained segments of the AI semiconductor ecosystem — precisely where SK Hynix maintains a strong foothold.
SanDisk Index Addition Boosts Sector Sentiment
SanDisk will officially enter the Nasdaq-100 index prior to market open on April 20, taking the place previously held by Atlassian. The announcement propelled SanDisk shares higher by 11.83% while simultaneously boosting optimism throughout the memory and storage industry.
When companies join major indices, they typically experience inflows from passive investment vehicles, which can elevate not only the included stock but also peers operating in similar markets. SK Hynix clearly benefited from this positive contagion effect.
The relationship between these two companies extends beyond market dynamics. SK Hynix and SanDisk have partnered to develop High Bandwidth Flash (HBF) — an innovative memory technology engineered to complement HBM in AI computing environments.
HBF aims to address performance and storage limitations in existing AI hardware architectures, especially as data center operations and inference computing demands continue expanding.
Improved Profit Outlook and Price Power
The record-breaking performance reflects more than market enthusiasm — fundamentals are strengthening as well. Korea Investment & Securities elevated its annual earnings projection for SK Hynix by a substantial 28%.
The revision stemmed from better-than-anticipated pricing dynamics across both DRAM and NAND memory product lines.
SK Hynix serves as a crucial component supplier to numerous global technology leaders, including Apple and Nvidia. The company’s trajectory remains closely linked to the expansion of worldwide AI infrastructure investments.
Performance among U.S. technology stocks continues influencing SK Hynix’s market trajectory due to these strategic supply partnerships.
The American depositary receipt equivalent for SK Hynix, listed under ticker HXSCL, advanced more than 7% during the corresponding session.
SanDisk concluded trading with an 11.83% gain on the Nasdaq exchange, with the index inclusion announcement serving as the primary catalyst behind the movement.
