STOCK3D BY FYNCA

Research updates

Material changes to stock3d’s company universe, source mappings and research methodology.

September 17, 2026 — company and component audit

Reviewed the 100-company universe, eight sector memberships and 35 illustrated assembly parts. The audited evidence categories contain 44 companies with humanoid evidence, 49 with broader robotics products and 7 with adjacent technology.

Four replacements preserved 100 unique listings: Ningbo Tuopu replaced Ricoh; Sanhua replaced BYD; Keli Sensing replaced Great Power; SUNON replaced Power Integrations. These changes addressed relevance and missing component roles, not expected investment performance.

Corrected memory, cooling, reducer-architecture, sensing and mechanical-support mappings. Structural links and tendon cables remain without a verified direct match.

The company research records preserve the supporting primary sources and caveats. The audit does not establish an objective top-100 ranking by humanoid revenue or market share.
