On July 16, Ciena fell 3.01% in regular trading, trading at $397.735/share, with turnover of $79.63 million.

On the news front, the company disclosed on July 15 that a major shareholder plans to sell securities. This coincides with continued profit-taking across the optical communication sector, which had rallied sharply on July 9 following catalysts related to NVIDIA's ultra-high capacity long-distance transmission project estimated at $5-10 billion over three years. A brief rebound on July 14 proved short-lived as selling pressure resumed.

The broader Communication Equipment sector declined in tandem, with Applied Optoelectronics down 6.12%, Nokia Oyj down 5.94%, Lumentum down 5.04%, and Arista Networks down 3.89%. Investment bank Stifel previously noted that current AI hardware selling should be viewed as rational valuation adjustment rather than demand weakness.

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%. Multiple institutions maintain overweight ratings, with BNP Paribas recently raising its price target to $640.
