Ciena is trading higher today, continuing a period of positive momentum driven by a series of bullish analyst initiations and research calls focused on the company's role in artificial intelligence networking. This follows a notable surge earlier in the week when the stock climbed 6% on the back of upbeat sell-side sentiment. The broader communication equipment sector is also participating in today's move, with peers like Lumentum Holdings, Coherent, and Celestica all posting gains that mirror the upward trend in Ciena shares.
