A Yahoo Finance report had examined how Lumentum Holdings' optical components are supporting the buildout of next-generation AI data center infrastructure, positioning the company as a beneficiary of rising AI-related data demand. The piece framed Lumentum as a key enabler of the physical infrastructure underpinning AI growth. That thesis played out in trading as Lumentum, alongside fellow optical component maker Coherent, became the two biggest gainers in the S&P 500 for the session. Analysts said investors are increasingly looking further down the AI data-center supply chain for signs of continued demand amid broader concerns about a potential slowdown in AI-related spending.
