Nabtesco operates across RV precision reducers. It is +7.5% in 2026. The stock (+7.5%) and its demand side (avg -10.5%) are moving in step. Among connected nodes the furthest ahead is FANUC (-4.5%) and the furthest behind is Tesla (-21.3%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. With Harmonic Drive, one of the two pillars of robot reducers.
