Memory stocks surge as SK Hynix jumps 7% and Seagate rallies 5% amid broad sector buying

SK Hynix shares rose 7% and Seagate climbed 5% on a strong buying wave across the memory and storage sector, even as the broader market declined. The Roundhill Memory ETF gained 5%, highlighting growing demand for high-bandwidth memory used in AI and large-scale data storage. SK Hynix benefits from rising DRAM and NAND prices tied to AI infrastructure, while Seagate sees robust cloud data center demand. This sector-wide rally reflects a repricing of memory technologies, though no new company-specific news was reported. Investors should watch if this momentum sustains amid upcoming data center spending updates.
