What happened
Ciena (CIEN) stock jumped 6.7% to $371 on Monday after Evercore ISI upgraded it to Outperform, raising its price target to $550 from $375, citing AI data center demand for optical networking equipment. Evercore analyst Amit Daryanani called connectivity inside data centers a critical bottleneck for running large AI models — a problem he argued Ciena is uniquely placed to solve as the only major company focused entirely on optical networking systems. Ciena's fiscal third quarter revenue was $1.67 billion, up 37% compared with a year ago, with adjusted earnings per share up 215% year-on-year. Evercore sees the optical networking market reaching $52 billion by fiscal 2029 at a 24% annual growth rate.
Why it matters
Ciena sits at the center of a bottleneck that stands between today's AI models and the computing power they need: the optical fiber links that carry data through and between data centers cannot be upgraded fast enough to keep up with AI demand. That bottleneck is driven by physical infrastructure limits, not just software trends, making Ciena's growth less susceptible to a normal tech cycle. Evercore's upgrade signals that Wall Street may have underestimated how long and how fast the optical networking boom can last.
