On June 11, Ciena rose 3.07% in regular trading, trading at $446.34/share, with trading volume of $254 million, rebounding after multiple consecutive sessions of decline.

On the news front, Argus Research raised its price target on Ciena from $370 to $650, maintaining a Buy rating, serving as a near-term rebound catalyst. Earlier, Morgan Stanley raised its target to $490 and Raymond James lifted its target to $530, both citing robust cloud and AI-driven demand.

Ciena had retreated from approximately $523 to around $426 after announcing a proposed $2 billion convertible senior notes offering due 2031, which triggered dilution concerns, compounded by post-earnings profit-taking. Fundamentally, the company reported fiscal Q2 revenue of $1.57 billion, up 40% year-over-year, with adjusted EPS of $1.64, up 290%, both exceeding consensus. Full-year revenue guidance was raised to $6.3 billion. Additionally, Ciena and Colt Technology demonstrated record-speed quantum-safe transatlantic data transmission at 800-gigabit Ethernet rates, underscoring the company's technology leadership.
