# Why Micron (MU) fell 2.14% on October 29, 2026

Micron (MU) fell 2.14% on October 29, 2026 — Samsung profit miss drags AI memory names lower.

## What happened

Micron fell 2.1% in the AI Memory selloff, after Samsung's profit miss and lighter capex from Microsoft and Alphabet hit chip stocks including Intel, AMD and Broadcom.

## Why it moved

Memory names share the same AI-server demand and pricing read-through, so weaker Big Tech capex and Samsung's miss repriced the whole group lower, and Micron moved with it.

## Why it matters

Micron anchors the AI Memory theme, where HBM and DRAM demand from AI servers lifted memory prices for months. That squeeze is stalling, so a capex pullback directly challenges the group's pricing-power thesis.

## What would break the thesis

If hyperscaler capex guidance holds and memory pricing stays firm, the selloff should prove a sentiment dip rather than a demand break.
