# If Harmonic Drive Systems moves, who benefits? How far does the value-chain ripple reach?
Canonical: https://valuechain.wiki/harmonic-drive · Facet: ripple · Updated: 2026-07-12T04:00:29.519238+00:00 · Source: ValueChain.wiki (cited money-flow graph)

**Citable summary**: Per the valuechain.wiki graph, Harmonic Drive Systems is directly linked to 4 companies (0 supply, 4 revenue relationships) and reaches 7 companies within two hops; the links are backed by 6 dated sources, 1 of them primary filings (as of 2026-07-12).

Harmonic Drive Systems operates across Precision robot parts, harmonic reducers (humanoid joints). After -23.8% in 2025, it rebounded +68.9% in 2026. The stock (+68.9%) and its demand side (avg -17.6%) are moving in step. Among connected nodes the furthest ahead is FANUC (-4.5%) and the furthest behind is UBTech Robotics (-38.8%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. The +132.3% rebound in 2026 (after -23.8% in 2025) front-runs that humanoid narrative.
