Up 1,600% Over the Past Year, Does Lumentum Stock Have More Room to Run?

Demand for high-precision lasers is rising. As artificial intelligence (AI) workloads expand and cloud companies upgrade their optical infrastructure, the need for faster, more reliable technologies grows. Lumentum Holdings (LITE), long a low-profile player, is now gaining attention. Known for its expertise in indium phosphide and advanced laser technologies, the company has moved beyond telecom roots to become a key supplier in AI-driven data center infrastructure. But that low-profile phase now looks like a thing of the past.

No surprise, then, that the stock has rocketed 1,600% over the past year, driven by powerful hyperscale demand. What began as a steady rise in 2025 has turned into a full breakout in 2026, fueled by strong AI-led catalysts. It may be a coincidence that Lumentum rhymes with “momentum,” but the stock’s performance clearly reflects that trend.
