On July 21, Ciena rose 5.58% in regular trading, trading at $400.4/share, with turnover of $82.68 million.

On the news front, the optical communications sector stabilized and extended its rebound momentum after consecutive days of pullback since July 13. The sector had previously corrected following profit-taking pressure triggered by major shareholder sell-off disclosures and a sharp rally catalyzed by NVIDIA's ultra-high capacity long-distance transmission network project. Selling pressure has now been gradually absorbed, with communication equipment peers broadly strengthening — Lumentum up 6.08%, Nokia up 5.06%, Applied Optoelectronics up 5.56%, and Arista Networks up 3.91%.

On fundamentals, Ciena's latest interim report showed revenue of $2.998 billion, up 36.38% year-over-year, with net income surging 588.26% year-over-year. Multiple institutions maintain overweight ratings, with BNP Paribas recently raising its price target to $640 from $625 while maintaining an Outperform rating. The NVIDIA long-distance transmission network project, estimated at $5–10 billion over three years, remains a key medium-term catalyst for Ciena.
