# Why GigaDevice (GIGADEV) fell 2.64% on October 31, 2026

GigaDevice (GIGADEV) fell 2.64% on October 31, 2026 — AI memory selloff drags peers lower.

## What happened

GigaDevice slipped 2.6% as the AI Memory group sold off after the Nasdaq fell 975 points on Intel's results and AI-spending worries. The move was sector-driven, with no company-specific catalyst.

## Why it moved

GigaDevice is a smaller memory-adjacent name that moves with the group's sentiment, so it fell in step with the sell-off at a much lower beta than Kioxia.

## Why it matters

The AI Memory theme is driven by AI servers pulling HBM and DRAM supply, lifting memory prices for months. The current selloff is testing whether that pricing strength can hold.

## What would break the thesis

A rebound in the broader chip group would likely lift GigaDevice with it. Persistent AI-spending doubts across the sector would weigh on the name even without company news.
