YTD as of 2026-09-04 · source: Yahoo Finance

ASE Technology is the World’s largest OSAT (packaging & test). Momentum stayed firm and it is +135.3% in 2026. The supply side (avg +168.4%) has moved harder than the stock (+135.3%). That is the classic bottleneck pattern: supplier volume leverage is being priced before this layer's own margin. Among connected nodes the furthest ahead is Samsung Electro-Mechanics (+402.2%) and the furthest behind is NVIDIA (+23.7%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. It absorbs CoWoS advanced-packaging and test volume that TSMC overflows, serving AI-chip customers such as Nvidia and AMD; advanced-packaging revenue jumped from $0.45B (2024) to $1.1B (2025).
