Full Analysis
Western Digital (WDC) shares fell 5% and Micron Technology (MU) dropped 6% on Tuesday amid a broader semiconductor sector sell-off, while SanDisk (SNDK) remained flat, showing relative strength in the memory and storage complex. The decline is attributed to profit-taking after significant year-to-date gains, with WDC up 206% YTD and Micron up 233% YTD through Monday's close, rather than a fundamental breakdown in their business models or earnings outlooks. Western Digital, now focused solely on hard disk drives following the spin-off of its flash business, recently reported four consecutive EPS beats with revenue of $3.34 billion in late April. CEO Irving Tan highlighted that virtually every AI workload requires persistent, cost-efficient data storage on HDDs, suggesting the current pullback is positioning rather than a thesis break. The company's fundamentals remain intact despite the intraday dip. SanDisk demonstrated resilience with Q3 FY2026 revenue of $5.95 billion, beating consensus by 26% and achieving non-GAAP EPS of $23.41 against a $14.66 estimate. Gross margins expanded significantly to 78% from 23% a year earlier, driven by a shift toward high-value datacenter markets where revenue jumped 645% year over year. Additionally, the company retired $650 million in debt to achieve a zero long-term debt balance sheet, reinforcing its financial stability. Analysts note a potential structural NAND shortage extending to 2028 and point to SanDisk's five multi-year New Business Model agreements that lock in firm financial commitments. While Reddit sentiment on WallStreetBets remains bullish for Micron despite the stock slide, traders are advised to monitor whether SanDisk can avoid breaking down into the close as broader chip tape volatility continues.
