On July 31, Ciena rose 5.62% in regular trading, trading at $391.15/share, with turnover of $135 million. The stock continued its recovery alongside the broader optical communications sector.

On the news front, the optical communications sector had previously experienced sustained selling pressure triggered by Corning's disappointing earnings guidance. After multiple days of adjustment, selling pressure has been gradually absorbed, with sector constituents staging a broad-based rebound over the past two sessions. Applied Optoelectronics gained 8.97%, Arista Networks rose 5.41%, Lumentum added 5.17%, Nokia climbed 2.48%, and Cisco advanced 1.93%.

On fundamentals, Ciena's latest interim report showed revenue of $2.998 billion, up 36.38% year-over-year, with net profit surging 588.26%. BNP Paribas previously raised its target price to $640 while maintaining an outperform rating. The combination of robust company fundamentals and sector-wide recovery momentum has supported the stock's upward move.
