The semiconductor sub-industry manufactures the integrated circuits, processors, and chips that power every digital device on earth. From NVIDIA's AI GPUs to Qualcomm's mobile modems, chip companies sit at the foundation of the modern technology economy. Semiconductor stocks are highly cyclical, driven by inventory cycles, capital expenditure waves from hyperscalers, and breakthrough demand cycles like the current AI infrastructure build-out.
Watch fab utilization rates, book-to-bill ratios, and hyperscaler capex guidance. Inventory corrections signal 6–12 month downturns. AI accelerator order backlogs at NVIDIA and TSMC are leading indicators for the entire sector.
