Western Digital's stock, despite a 139% year-to-date gain, is seeing profit-taking, aligning with broader weakness in the hard disk drive (HDD) group. Seagate's decline is attributed to HDD pricing and sentiment rather than company-specific news. Meanwhile, the Roundhill Memory ETF (DRAM) is little changed, supported by heavy DRAM weightings from Samsung, SK Hynix, and Micron, suggesting a rotation rather than a broad storage repricing.
