Why Western Digital (WDC) fell 7.91%
Western Digital (WDC) fell 7.91% on November 5, 2026 — Broad tech selloff drags Western Digital lower.
What happened
Asian chip stocks slid as disappointing Qualcomm and Arm earnings weighed on the group, pulling Western Digital down 7.9%. The drop was part of a broader AI Memory selloff.
Why it moved
Western Digital moves with the storage complex, so the sector-wide repricing on weaker chip earnings dragged it lower. Its move reflects shared demand expectations, not a company-specific event.
Why it matters
Western Digital sits in the AI Memory theme, where AI data demand tightened DRAM, HBM and NAND supply for months. That tide is now breaking as AI-spend doubts and weak mobile demand weigh on the group.
What would break the thesis
Stabilizing chip earnings and steady AI storage demand would limit the damage and could bring the group back.
