Rate Rise Caps Memory Boom as Micron, SanDisk, Western Digital Decline
Memory and storage names fell 5–7% as rising Treasury yields compressed their valuations, snapping a strong 2026 run (MU +255%, SNDK +653%, WDC +211% YTD). Seagate and the Roundhill Memory ETF also slid about 6%, with the move attributed to a macro rate reset rather than company-specific news. The AI infrastructure story remains intact on the fundamentals, but investors should consider smaller positions given the higher cost of capital and lofty gains.
