# Why SanDisk (SNDK) fell 2.80% on September 29, 2026

SanDisk (SNDK) fell 2.80% on September 29, 2026 — Chip stocks slide as U.S.-Iran tensions hit tech.

## What happened

Broad semiconductor selloff triggered by renewed U.S.-Iran tensions and oil price spike, dragging down the entire chip sector including NAND storage players.

## Why it moved

SanDisk exposure to NAND flash moves with sector risk-off; geopolitical escalation forces de-risking of memory and storage stocks as investors flee cyclical tech positions.

## Why it matters

Within AI Memory, NAND flash already faces near-term oversupply headwinds that compound the sector-wide selloff — SanDisk is caught between macro flight-to-safety and structural NAND glut.

## What would break the thesis

Geopolitical stabilization could restore sector bid, but NAND oversupply cycle suggests a slower recovery relative to DRAM-weighted peers; watch for demand destruction in PC and consumer storage.
