Why Western Digital (WDC) fell 6.16%
Western Digital (WDC) fell 6.16% on November 13, 2026 — AI memory selloff drags storage names lower.
What happened
Western Digital fell 6.2% as the AI Memory group sold off on chipmaker weakness, led by Nvidia's slide, which also pulled the S&P 500 and Nasdaq lower. The decline was sector-wide, not from company news.
Why it moved
Western Digital's hard drives and storage products are tied to the same AI infrastructure spending that drives memory demand. When AI-chip sentiment sours, storage names are repriced together.
Why it matters
The AI Memory theme points to AI server demand lifting memory and storage pricing for months. Western Digital sits in the storage leg of that trade, where AI datacenter buildouts are the key demand driver.
What would break the thesis
If AI infrastructure spending holds and chip leadership recovers, the group should rebound. Doubts about neocloud demand or a slowdown in datacenter storage orders would challenge the thesis.
