On July 29, Ciena fell 5.14% in regular trading, trading at $332.69/share, with turnover of $257 million. Sustained selling pressure across the optical communications sector continued to weigh on the stock.

On the news front, Corning's earnings guidance disappointed the market, triggering broad-based selling across optical communications names. The sector saw widespread declines, with Applied Optoelectronics down 9.26%, Lumentum down 7.19%, Arista Networks down 5.85%, and Nokia down 4.82%. The prior attempted rebound in the sector failed to sustain momentum as selling pressure remained undigested.

On the fundamental side, Ciena's latest half-year 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 and maintained an outperform rating. However, systematic sector-wide selling pressure continues to suppress the stock in the near term despite solid company-level fundamentals.
