Nokia Oyj's stock plummeted 5.01% in pre-market trading on Friday, reflecting a sharp reversal from recent gains driven by high-profile AI partnerships.

The decline represents concentrated profit-taking after the stock's rallies following announcements of expanded collaborations with Amazon Web Services and Google Cloud were fully digested by the market. Nokia recently revealed its Autonomous Networks Fabric platform would launch on AWS later this year, integrating AI tools to help telecom operators automate operations, while Google Cloud expanded its deal to embed Gemini AI models into Nokia's network software.

The broader communication equipment sector also faced significant pressure during the pre-market session, with multiple optical communication stocks experiencing substantial declines, amplifying the selling pressure on Nokia. This pattern mirrors previous selloffs where partnership-driven gains were quickly priced in, triggering profit-taking from investors.
