SK Hynix ADR Surge Sparks Rebound in AI Memory Stocks

Demand for high-bandwidth memory and advanced chips surged with the expansion of AI training, but a recent pullback in memory shares raised concerns that the industry cycle may be weakening. Morgan Stanley argues the retreat is a temporary disruption within an AI supercycle, as the rise of agentic AI and inference workloads makes memory an increasingly critical bottleneck for computing capacity.

Morgan Stanley’s semiconductor analyst has turned bullish on the memory sector after adopting a bearish view in July, saying the positioning correction is nearing an end. In the latest report, the analyst estimated that both Samsung Electronics and SK Hynix offer potential share-price upside of more than 60%, supported by growing memory requirements from agentic AI systems and inference workloads.

SK hynix sits at the center of the artificial-intelligence hardware boom as demand for high-bandwidth memory, or HBM, expands alongside investment in AI servers and data centers. That exposure has made the chipmaker a bellwether for South Korea’s technology sector. A recent wave of leveraged position unwinding had intensified losses across semiconductor shares, leaving investors focused on when forced selling would subside and whether capital would return to the AI supply chain.

Sentiment improved as investors judged the market’s deleveraging cycle to be nearing an end and SK Group Chairman Chey Tae-won increased his holding in SK hynix. The move was viewed as a vote of confidence in the memory-chip maker and the broader AI investment cycle, helping drive the KOSPI up more than 16%. The report did not disclose the stake size, transaction value or exact purchase date, while analysts said AI infrastructure spending remained supportive of semiconductor demand.

The rapid buildout of artificial-intelligence data centers is fueling demand for high-bandwidth memory, a critical component used alongside advanced AI processors. UBS said the shift could make the historically cyclical memory-chip industry more structurally driven by AI investment, positioning SK Hynix to benefit from its HBM technology and supply relationships with major global technology companies.

UBS initiated coverage of SK Hynix’s American depositary receipt with a Buy rating and a $204 price target in its latest report. As of July 31, 2026, the bank said the memory maker’s earnings momentum remained intact as hyperscalers continued expanding AI infrastructure, supporting strong HBM demand and a longer-lasting growth cycle for the broader memory industry.

SK Hynix is a major South Korean memory-chip maker and a key supplier of high-bandwidth memory, or HBM, to NVIDIA. As generative AI and high-performance computing expand, HBM has become a critical component in AI accelerators, prompting investors to reassess the company’s growth potential and industry position.

In the latest trading as of July 2026, SK Hynix’s market capitalization exceeded $1 trillion, making it the third Asian company to cross that threshold. Its shares have doubled so far this year and reached a record high, bringing its market value close to that of Samsung Electronics. Micron also crossed the $1 trillion mark over the same period, while UBS raised its price target for the company to $1,525.

SK Hynix is a leading global supplier of DRAM and NAND memory and a major producer of high-bandwidth memory for AI servers. As investment in generative AI infrastructure expands, rising purchases of servers and enterprise SSDs have made memory prices a key driver of the company’s earnings and share price.

KB Securities raised its price target for SK Hynix to 1.9 million won in its latest report and forecast that the company’s operating profit could reach 40 trillion won in the first quarter of 2026, far above market expectations. The report said demand from AI servers and enterprise SSDs was driving sharp increases in DRAM and NAND prices, with that momentum expected to continue supporting the business.
