YTD as of 2026-09-04 · source: Yahoo Finance
King Yuan Electronics (KYEC) is the World’s largest pure-play test OSAT. It is -6.7% in 2026. The supply side (avg +57.3%) has moved harder than the stock (-6.7%). 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 MediaTek (+152.4%) and the furthest behind is Qualcomm (+0.2%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. Provides wafer probing and final test mainly to fabless (80%+) and IDMs, using Advantest and Teradyne testers.
