On July 30, Ciena rose 5.64% in pre-market trading, trading at $349.05/share, with turnover of approximately $1.27 million.

On the news front, the optical communications sector is staging a broad-based rebound after consecutive sessions of selling pressure initially triggered by Corning's disappointing earnings guidance. Following multiple days of correction, selling pressure has gradually been absorbed, with sector peers rallying in tandem — Nokia up 6.31%, Lumentum up 5.42%, Applied Optoelectronics up 5.41%, and Arista Networks up 2.89%.

On the fundamental side, Ciena's latest interim report showed revenue of $2.998 billion, up 36.38% year-over-year, with net profit surging 588.26% year-over-year. BNP Paribas previously raised its target price to $640 and maintained an outperform rating.
