Market mechanism
Valuation expansion driven by AI-related optical networking backlog.
Extended read
Ciena's performance in 2026 reflects the massive capital rotation into networking infrastructure. As AI clusters grow, the need for high-speed optical interconnects has surged, leading to a record backlog for Ciena. However, the current trailing P/E of 153x indicates that the market has priced in several years of flawless execution. Investors are weighing the massive backlog against the risk of a 'digestion period' in AI spending, which could lead to significant multiple contraction.
