# Why SanDisk (SNDK) fell 19.86% on November 6, 2026

SanDisk (SNDK) fell 19.86% on November 6, 2026 — Microsoft neocloud fears drag memory names lower.

## What happened

SanDisk fell 19.7% as memory names sold off together in a broad tech selloff. The shared catalyst cited was Microsoft increasing oversight of neocloud providers amid data center delays and rising costs.

## Why it moved

SanDisk trades as a high-beta AI-memory name, so it fell with the group when broad tech sold off. A headline pointing to slower data center buildouts and higher costs adds pressure on expected AI storage demand.

## Why it matters

AI Memory's thesis is that AI data demand tightened DRAM, HBM and NAND supply for months. Today's drop shows that tide breaking as AI-spend doubts and weak mobile demand spread across the group.

## What would break the thesis

If the Microsoft oversight move turns out to be routine and the broad tech selloff stabilizes, SanDisk could recover quickly. Further data center delays or confirmed capex cuts would extend the decline.
