# Why SanDisk (SNDK) fell 20.40% on July 28, 2026

SanDisk (SNDK) fell 20.40% on July 28, 2026 — China roadblocks hit SanDisk and chip stocks.

## What happened

US tightened chip export restrictions to China, directly hitting memory/storage makers like SanDisk.

## Why it moved

China is a key market for SanDisk; export barriers shrink addressable revenue and force downward earnings repricing.

## Why it matters

The AI memory supercycle is intact, but geopolitical supply-chain fragmentation is narrowing sector growth trajectories — US-China tech conflict is now a structural demand headwind for memory chips.

## What would break the thesis

If Beijing eases restrictions or SanDisk shows it can pivot revenue to non-China markets, much of this downside reverses.
