# Why Applied Optoelectronics (AAOI) fell 5.04% on October 13, 2026

Applied Optoelectronics (AAOI) fell 5.04% on October 13, 2026 — AI funding fears hit optical networking demand.

## What happened

Applied Optoelectronics dropped 5% as AI funding fears hit optical networking stocks, extending a sell-off that also weighed on Lumentum and Coherent.

## Why it moved

AAOI makes transceivers that link data-center switches and servers, so its revenue depends directly on how fast hyperscalers and AI cloud operators are building out.

## Why it matters

AAOI is one of the smaller pure plays in the AI Optics & Interconnect theme, where optical components are a bottleneck for the AI compute supercycle.

## What would break the thesis

Strong data-center spending or a rising backlog that outruns the funding scare would reverse the move. Any sign that customers are delaying or cutting optical orders would validate the selloff.
