    Ciena Stock Doubles in H1 2026 on AI Optical Demand

    Question

    Ciena Stock Doubles in H1 2026 on AI Optical Demand

    Direct answer

    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.
