Sector Taxonomy v1
How EQTRun classifies every security into a sector, an industry group, and an industry. Curated on top of Yahoo Finance — not GICS.
Why not GICS?
The Global Industry Classification Standard (GICS) is jointly owned by MSCI and S&P Dow Jones Indices and is licensed for commercial use. Building EQTRun on top of a GICS mapping we don't own would either require an expensive license or risk an IP dispute.
Instead, we use Yahoo Finance's sector and industry labels as the foundation — free, globally consistent across 70+ exchanges, and updated automatically whenever a company changes its reporting classification. Yahoo uses 11 top-level sectors and about 200 distinct industries.
On top of that, we curate 39 industry groups — a middle layer that bundles related industries (e.g. "Banks" covers both Regional and Diversified, "Semiconductors" covers chip makers plus equipment vendors). The groups are used to build the EQTR Tree Explorer nodes and the equal-weight industry indexes used throughout the platform.
If a security changes sector on Yahoo Finance, the classification on EQTRun updates on the next metadata refresh. We do not store historical sector membership — the latest Yahoo label is always used.
Version: v1 — April 2026. The taxonomy is versioned; if we change the sector/group structure meaningfully we'll bump the version and keep v1 documented here for anyone with existing integrations.
