Most Popular Narrative: 26% Overvalued

Ciena's widely followed narrative price target stands well below the recent share price, highlighting a double-digit valuation gap that has investors talking. This sets up a major tension around whether growing momentum can keep up with current expectations.

Ciena's industry-leading solutions (WaveLogic 6, RLS platform, pluggables, DCOM) are rapidly becoming de facto standards for AI network infrastructure, resulting in sizable multi-hundred-million-dollar orders, a record order book, and strong visibility into 2026 growth. This suggests consensus revenue estimates may be too conservative.
