Why Is APPLIED OPTOELECTRON (AAOI) Stock Up Today?

Applied Optoelectronics (AAOI) shares rose 17.69% to $56.87, driven by a broader rally in optical networking stocks following strong results from CoreWeave. The move reversed a recent decline, as investors returned to AI-related hardware names.

What Happened

The primary catalyst was CoreWeave’s earnings report, which revived interest in the AI trade. This sentiment lifted peers such as Lumentum, which jumped 11%, and Coherent, which climbed 7%. Applied Optoelectronics stock changed hands at $54.03 shortly after the open, up 12%, before continuing its ascent. The company had previously faced pressure after a Q4 guidance miss, but the sector-wide momentum appeared to override that concern. B. Riley Securities maintains a Neutral rating on the stock with a price target of $45.
