AT&S operates across High-end IC substrates (HBM, 3D). It surged +188.9% in 2025 and +334.1% in 2026. The stock (+334.1%) is ahead of both its demand side (avg +141.3%) and supply side (avg +60.7%). Having run ahead of its chain, it is the first spot to give back if customer numbers fail to follow. Among connected nodes the furthest ahead is Intel (+159.6%) and the furthest behind is Ajinomoto (+47.8%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look.
