Western Digital’s shares fell 8.4% to an intraday low of $419.54 in morning trading on Monday, extending a recent retreat in AI-exposed technology equities. The decline occurred against a backdrop of rising U.S. Treasury yields, which pressured valuations for high-multiple memory stocks that had surged earlier in 2026.
The stock, which had rallied from a 52-week low of $76.70 to a peak of $799.87 in June, has become increasingly sensitive to shifts in investor sentiment following its extraordinary gains. The broader NASDAQ Composite dropped nearly 1.0% on the day, reflecting a risk-off session across high-beta technology assets.
Sector peers including Seagate Technology, SanDisk, and Micron Technology also recorded double-digit declines in recent sessions, underscoring the broad-based retreat in memory and storage stocks tied to artificial intelligence demand. Western Digital’s underlying business fundamentals remain intact, with strong revenue growth reported in fiscal year 2026 and sustained demand for AI-driven storage solutions.
Insider activity has added to valuation concerns, with tens of millions of dollars in stock sales over the past year and no offsetting purchases. Analysts note that while the company’s operational performance remains robust, the stock’s prior surge has left it particularly vulnerable to macroeconomic headwinds, including rising borrowing costs and shifting market sentiment.
