Memory and storage stocks including Micron, SanDisk, and Western Digital dropped 5-7% due to rising U.S. Treasury yields increasing the cost of capital and discount rates on future earnings. This selloff is a valuation reset after a strong 2026 rally, not driven by changes in memory fundamentals like pricing or demand. The sector remains supported by AI-driven demand for memory chips, but higher financing costs and lofty valuations are causing the pullback. Investors should watch Treasury yields, memory pricing trends, and technical levels for further direction.
