On August 28, Ciena fell 3.17% in regular trading, trading at $387.04/share, with turnover of approximately $155 million.

On the news front, the optical communication sector's two-day technical rebound came to an end, with the group resuming its downward trajectory. The persistent market narrative around \"compute capacity cyclical oversupply\" continued to weigh on upstream hardware supply chain names. Peers Applied Optoelectronics fell 5.19%, Lumentum dropped 4.87%, and Nokia declined 1.79%, reflecting broad-based selling pressure across the sector.

On the institutional side, Bank of America previously cut its price target on Ciena sharply from $660 to $550, noting that supply constraints are limiting full-year revenue upside potential. The firm nonetheless maintained its Buy rating, citing robust underlying demand. Additionally, Northland Capital recently upgraded Ciena to Outperform with a $500 target. The market's attention is now turning to Ciena's fiscal Q3 earnings report scheduled for September 4, with key focus areas including backlog conversion, 800G pluggable module ramp, and cloud customer growth trends.
