SK Hynix shares tumbled more than 15% in Seoul trading following its successful Nasdaq debut that raised over $26 billion. The decline marks the company's biggest one-day drop on record, driven by profit-taking and concerns over HBM4 chip shipments falling short of second-quarter expectations. Despite the volatility, analysts maintain the long-term outlook remains strong for the AI memory market leader.

Profit-taking and HBM4 chip shipments drive investor concerns

The sharp decline was driven by multiple factors, with profit-taking emerging as a primary catalyst after SK Hynix's Korean shares more than tripled earlier this year

4

. Ryu Young-ho, a senior analyst at NH Investment & Securities, noted that investors were cashing out following the conclusion of the U.S. listing

4

. More significantly, concerns emerged that shipments of the company's next-generation HBM4 chip shipments may have fallen short of lofty second-quarter expectations

1

. Investors had anticipated that HBM4 shipments would increase from the second quarter, but the increase does not appear to have materialized at scale

4

. Diminishing earnings optimism also played a role, as investors moderated expectations due to SK Hynix's greater exposure to High Bandwidth Memory chips compared to Samsung Electronics, which means the company was set to benefit less from a recent rise in prices for conventional DRAM chips

AI memory market dominance remains despite stock volatility

Despite the stock volatility, SK Hynix continues to dominate the AI memory market, maintaining its position as the leading supplier of advanced High Bandwidth Memory chips used in AI servers by customers including Nvidia and Alphabet's Google

1

. The company held a commanding 58% revenue share of the global HBM market in the first quarter, significantly ahead of Samsung Electronics and Micron Technology, which each held 21%

4

. This leadership position reinforces SK Hynix as a key beneficiary of AI-driven demand for high-bandwidth memory used in artificial intelligence applications

1

. The volatility in SK Hynix shares has surged this year as it became a target of global investors betting on sustained profit growth from a shortage of high-bandwidth memory chips used in AI data centers

Long-term outlook for AI chip production remains intact

Analysts emphasized that Monday's decline reflected profit-taking rather than a fundamental shift in the company's long-term outlook
