# Why SanDisk (SNDK) fell 6.87% on October 16, 2026

SanDisk (SNDK) fell 6.87% on October 16, 2026 — Broad tech selloff drags AI memory names lower.

## What happened

SanDisk fell 6.9% as the broad tech selloff rolled through semiconductors, with FormFactor, Teradyne, Applied Materials, AMD, and Intel all breaking lower.

## Why it moved

SanDisk trades with the chip complex on shared AI-server demand and risk sentiment, so when leading semis sell off, memory and storage names follow.

## Why it matters

Inside the AI Memory theme, HBM and DRAM tightness had been supporting storage names through AI server demand. Today's rout is a test of whether that tailwind can hold up when the broader tech tape turns.

## What would break the thesis

If the tech selloff deepens or storage pricing softens, SanDisk's margin pressure could become a company-level problem rather than a sentiment move.
