Within the broader US stocks landscape, optical names Lumentum and Coherent posted the S&P 500's biggest single-day gains, as investors dug deeper into the AI data-center supply chain for evidence that demand remains resilient.
The rally reflects a rotation among US stocks away from headline AI chipmakers toward secondary beneficiaries, with analysts citing this shift as a hedge against fears of a spending slowdown at hyperscale customers.
This dynamic suggests capital within US stocks is broadening beyond mega-cap AI leaders, a trend worth tracking as earnings season approaches and infrastructure spending data comes into focus.
