Why Is APPLIED OPTOELECTRON (AAOI) Stock Up Today?

Applied Optoelectronics (AAOI) shares rose 15.60% to $55.86, driven by a broader rally in optical networking stocks following strong results from CoreWeave. The move helped offset recent weakness, as the stock had fallen 30.0% over the previous eight sessions.

What Happened

Optical networking peers rallied sharply as CoreWeave pulled investors back into AI-related shares. Lumentum jumped 11% and Coherent climbed 7% in the same session. Applied Optoelectronics stock changed hands at $54.03, up 12%, shortly after the open before extending gains later in the day. This surge comes after the company missed Q4 guidance last week, which had previously placed pressure on the stock. The current momentum aligns with a wider tech rally, though the stock remains down almost 56% over the last month.
