A universe built on breadth
As of 6 November 2026, the tracked universe spans 2,479 companies across eight sectors. Technology leads decisively by headcount with 657 names — more than a quarter of everything we follow — anchored by Apple, Microsoft and NVIDIA, with AMD, Salesforce and Intel close behind. Industrials (475) and Healthcare (409) round out the top three, and Basic Materials (358) runs surprisingly deep. The tail thins quickly: Consumer Cyclical (186), Financials and Energy (149 each), and Communication Services (96) is the narrowest slice.
Where the weight sits
Rank the same sectors by aggregate market capitalisation and the picture inverts. Financials tops the table at roughly $159.5tn, followed by Energy ($106.6tn) and Basic Materials ($47.2tn). Technology, despite having the most constituents, sits fourth by weight ($23.1tn), ahead of Industrials ($12.4tn). Communication Services, Healthcare and Consumer Cyclical trail far behind — Consumer Cyclical totals just ~$581bn even though it holds Amazon, Tesla and Alibaba.
The divergence is the story
That inversion — most names in Technology, most weight in Financials and Energy — is the single most interesting feature of the data, and it deserves scepticism rather than a tidy narrative. A sector holding Amazon and Tesla cannot plausibly aggregate to under $600bn while Basic Materials, whose sample names are small-cap miners and fertiliser producers, totals $47tn. The likeliest explanation is visible in the data itself: duplicate cross-listings. Tesla appears as both TL0.F and TL0.DE, Alphabet as GOOG and GOOGL, Novo Resources as NVO.TO and NVO.AX, Galantas Gold as GAL.V and GAL.L, Obsidian Energy as OBE and OBE.TO. Where one issuer is counted several times, aggregate caps inflate unevenly. Treat the count column as the trustworthy lens and the cap totals as provisional.
Notable names
The marquee constituents are where you would expect: Apple, Microsoft and NVIDIA in Technology; Johnson & Johnson, UnitedHealth and AbbVie in Healthcare; Berkshire Hathaway, JPMorgan, Visa and Mastercard in Financials; Alphabet, Meta, Netflix and Tencent in Communication Services; Exxon, Shell and Reliance in Energy. The universe is also genuinely global — Xiamen Solex, Tencent, Alibaba, Oberbank and Reliance signal coverage well beyond US mega-caps.
What to watch
Three things. First, the breadth concentration in Technology means sector-level moves there will dominate the universe's internal breadth statistics. Second, the apparent heft of Financials and Energy should be checked against a de-duplicated cap before anyone reads it as a signal. Third, the thin Communication Services bench — 96 names, heavy on a handful of platforms — makes that sector the most exposed to single-name swings. The coverage is wide and global; the weighting needs cleaning before it can be trusted.
