Philadelphia Semiconductor Index Falls 4.01% as Chip Stocks Slide

The selloff is broad rather than concentrated, with AMD and Intel leading declines while ASML holds up comparatively better — a pattern suggesting the pressure is sector-wide rather than tied to any single company's news. Because chipmakers sit at the base of the AI and data-center supply chain, weakness here tends to register across the wider tech complex. Whether the decline broadens further or stabilizes around these levels is the open question worth watching.
