Coherent rebounds with AI hardware stocks after a 13% drop
What is behind the stock move?
Coherent recovered part of Thursday’s loss alongside a broader AI hardware rebound. Its November 4 earnings update offers context for the stock’s exposure to the sector: data-center and communications products accounted for most of the company’s September-quarter sales.

- Data-center and communications sales reached $1.95 billion. Coherent sells components that send data using light between servers and across networks.
