On October 6, Ciena rose 3.16% in regular trading, trading at $402.465/share, with Turnover of $71.9183 million. The rise was supported by a wave of investment bank rating upgrades focused on the company's role in AI-driven optical networking.

Bernstein initiated coverage with an Outperform rating and a $440 price target, while Evercore ISI had previously upgraded the stock to Outperform with a $550 target, citing Ciena's optical networking business as a key bottleneck in AI buildouts. Morgan Stanley noted the company expects roughly 30% compound annual revenue growth over the next three years and estimates about $12 billion in new data center market opportunities by 2029.

Fundamental support also came from the fiscal third quarter, when adjusted earnings per share reached $2.11, up 215% year over year, and the company raised its full-year revenue guidance to $6.42 billion, above market expectations.
