Stock Track | Ciena Plummets 5.15% Intraday as Optical Communication Sector Sees Profit-Taking After AI Rally

Stock Track05-15

Ciena's stock plummeted 5.15% during intraday trading on Friday, marking a significant decline for the optical networking equipment provider.

The drop appears to be part of a broader retreat across the optical communication sector, which is experiencing profit-taking pressure following a sharp, AI-infrastructure-driven rally earlier in the month. The sector had surged to historic highs on optimism over demand for AI-ready optical networking equipment for hyperscale data centers.

Ciena, which had accumulated substantial gains fueled by its positioning as a key provider for data center interconnection, is now facing sector-wide consolidation. The pullback reflects investors reassessing valuations after the recent rally, with several peers in the communication equipment space also trading lower.
