On September 16, Ciena rose 6.56% in regular trading, trading at $357.285/share, with turnover of $404 million. The stock rebounded sharply after a steep selloff on September 14, when shares plunged over 6% amid concerns triggered by major AI companies collectively calling for a slowdown in frontier AI model development.

On the news front, the broader optical communication sector rallied strongly, with Lumentum surging over 10%, Coherent and Applied Optoelectronics each gaining over 3%. Ciena also announced the launch of Ciena Ventures, a new corporate venture capital program with an initial commitment of $200 million, targeting early-stage companies across networking infrastructure, data center architectures, optical networking technologies, and emerging communications technologies.

Fundamental support remains solid. Ciena's fiscal Q3 adjusted EPS came in at $2.11, significantly beating the consensus estimate of $1.73 and representing a 215% year-over-year increase. Revenue reached $1.67 billion, also above expectations. The company raised its full-year revenue guidance to $6.42 billion, surpassing the market estimate of $6.34 billion. Analysts maintain an average overweight rating with a mean price target of $520.69.
