- SK Hynix climbed up to 9% on Tuesday, touching a record peak of 1,128,000 won.
- Robust AI enthusiasm and a tech sector rally on Wall Street fueled the advance.
- SanDisk’s addition to the Nasdaq-100 index on April 20, taking Atlassian’s place, lifted memory sector sentiment.

SK Hynix shares reached an unprecedented peak on Tuesday, propelled by surging AI chip requirements and the positive ripple effects from SanDisk’s forthcoming Nasdaq-100 entry.
The memory chipmaker based in South Korea saw its Seoul-traded shares climb as much as 9% during the session, touching 1,128,000 won—an all-time record for the semiconductor giant.
This impressive performance followed a strong showing on Wall Street the previous day. Tech equities spearheaded a market-wide advance, supported by ongoing optimism surrounding artificial intelligence infrastructure investments.
SK Hynix ranks among the leading producers of high-bandwidth memory (HBM), a critical element in AI chips manufactured by industry leaders such as Nvidia. HBM demand has outpaced available supply, providing SK Hynix with substantial leverage on pricing.
Market participants have been favoring firms with significant exposure to supply-limited segments of the AI semiconductor ecosystem—a category where SK Hynix occupies a central position.
SanDisk’s Index Addition Provides Additional Momentum
SanDisk will enter the Nasdaq-100 prior to market opening on April 20, taking the spot previously held by Atlassian. This development pushed SanDisk shares higher by 11.83% and generated positive sentiment throughout the memory and storage industry.
When companies join major indices, they typically experience passive fund purchases, which can elevate not only the included stock but also comparable companies in the sector. SK Hynix clearly benefited from this positive sentiment overflow.
Additionally, these two firms share an active technology collaboration. SK Hynix and SanDisk are working together to create High Bandwidth Flash (HBF)—an innovative memory architecture intended to complement HBM in artificial intelligence platforms.
HBF aims to address performance and capacity limitations in existing AI infrastructure, especially as data center operations and inference tasks continue expanding.
Improved Forecasts and Strong Pricing Dynamics
The historic rally reflects more than just market enthusiasm—it’s supported by strengthening business fundamentals. Korea Investment & Securities analysts increased their annual profit projection for SK Hynix by 28%.
This revision stems from better-than-anticipated pricing trends in both DRAM and NAND memory markets.
SK Hynix serves as a critical component supplier to major global technology corporations, including Apple and Nvidia. The company’s trajectory is intrinsically linked to the expansion of worldwide AI infrastructure.
Given these supply partnerships, U.S. technology stock performance continues to influence SK Hynix’s market results.
The American depositary receipt equivalent of SK Hynix, listed under ticker HXSCL, gained more than 7% in the same trading period.
SanDisk finished the session up 11.83% on the Nasdaq, with its index inclusion announcement serving as the primary driver behind the movement.
