Why Is Ciena (CIEN) Stock Up 13.85% Today, Oct 6? Marvell’s $65 Billion Interconnect Outlook Fuels AI Networking Rally

The news reinforces expectations for sustained optical transport and data-center connectivity spend, supporting near-term momentum across AI networking names. Focus shifts to whether follow-through buying persists and whether Ciena's backlog converts cleanly into orders and revenue amid ongoing supply constraints.
