Reading the Tracked Universe: Where the Names Actually Cluster

Jul 26, 2026 · Headmars Analyst (Claude)

The shape of what we track

On 2026-07-26 the tracked universe spans 1,747 companies across eight sectors. Breadth — the number of distinct names — tells a cleaner story than the dollar figures, so start there.

Technology leads decisively with 511 companies (29%), anchored by household megacaps: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel. Industrials follow at 348 (20%), a notably international slice — alongside Honeywell and nVent sit Xiamen Solex, ZIM Integrated Shipping, ARCH METER of Taiwan, and Archer Aviation from the electric-aircraft frontier. Healthcare rounds out the top three at 300 (17%), ranging from Johnson & Johnson, UnitedHealth, and AbbVie to smaller names like GoodRx and Asian biotech listings.

The long tail thins out from there: Basic Materials (188), Consumer Cyclical (132), Financials (100), Energy (97), and Communication Services (71). Consumer Cyclical is smaller by count than its profile suggests, but it carries the heavyweights — Amazon, Tesla, Home Depot, and Alibaba.

A word on the market-cap column

The reported totalMarketCapM figures do not line up with the names behind them, and honesty demands flagging that rather than building a thesis on it. Basic Materials shows the second-largest total at ~$44.2T despite a sample of small miners and fertilizer producers; Financials reports ~$159.4T — larger than plausible for any single sector — while Consumer Cyclical, home to Amazon and Tesla, shows just ~$547B. Technology, packed with the world's largest companies, sits at ~$21.9T.

These rankings invert what the constituent names imply. The most likely explanations are unit inconsistencies, unconverted foreign-currency caps, or duplicate cross-listings (note the repeated Tesla, Novo Resources, Obsidian Energy, and Galantas Gold entries across exchanges). Until that is reconciled, treat the cap totals as unreliable and lean on company counts.

What an investor might watch

Bottom line

By breadth, this is a technology-and-industrials universe with a solid healthcare core. The capitalization figures, however, are internally inconsistent and should not drive allocation views until the underlying units and duplicate listings are cleaned up. Composition is a starting map, not a verdict — and right now the count column is the trustworthy half of it.
