YTD as of 2026-09-04 · source: Yahoo Finance
Will Semiconductor operates across SSE 50 (Shanghai), CMOS image sensors, OmniVision (world #3). After +15.5% in 2025, it corrected -33.7% in 2026. The supply side (avg +41.9%) has moved harder than the stock (-33.7%). 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 TSMC (+41.9%) and the furthest behind is Xiaomi (-19.9%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. An SSE 50 (Shanghai) constituent.
