A new wave of artificial intelligenceAssociated stocks are emerging, with visual technology Companies are outperforming the broader market over the past year.
This increase was driven by the increasing demand for faster data transfer. Companies like Lumentum (NASDAQ: LITE) have led the rally, posting a staggering 1,137% gain over the past 12 months, making it one of the best-performing stocks in the world. Standard & Poor’s 500.
Applied Optoelectronics (NASDAQ:AAOI) is up 551%, Coherent (NYSE:COHR) is up 282%, Corning (NYSE:GLW) is up 223%, and Fabrinet (NYSE:FN) is up 176% over the same period.
This performance contrasts with the broader Nasdaq 100 index, which returned 23% over the same time frame, highlighting the intensity of investor interest in this niche sector of the AI ecosystem.
Why are optical stocks rising?
Notably, this rise was driven by the critical role these companies play in the next generation AI infrastructure. Optical components, which use light instead of copper wires, have become essential in data centers to efficiently handle massive data streams.
The shift from copper to optical solutions is accelerating as the industry works to overcome power and bandwidth limitations in larger AI clusters.
Technologies such as 1.6T transceivers, combined optics (CPO), and optical circuit switches (OCS) are at the forefront, supporting faster and more power-efficient data movement between GPUs and across racks.
Meanwhile, momentum has been fueled by massive capital expenditures for hyper-scale companies, which are expected to exceed $430 billion in 2026 alone.
Investor Enthusiasm received an additional boost in early March when Nvidia (NASDAQ: NVDA) announced plans to invest $2 billion in both Lumentum and Coherent, signaling strong confidence from a leading AI chipmaker in the long-term importance of optical networking solutions.
Meanwhile, Bank of America analysts forecast roughly 10% annual growth in the optical transport market for both 2026 and 2027, describing it as an “AI supercycle” supported by tight supply conditions and long lead times for capacity expansion.
However, some volatility emerged, with profit-taking in late March amid a widening range Semiconductors Weakness, although momentum has since rebounded with continued positive order flow and strong OFC demonstrations.
