How the universe breaks down
As of 7 October 2026, the tracked universe spans 2,335 companies across eight sectors. By count, it is unmistakably a technology book: Technology holds 634 names (27%), followed by Industrials at 446 and Healthcare at 384. Together those three sectors account for roughly two-thirds of everything tracked. At the thin end sit Communication Services (90), Financials (139), and Energy (141) — concentrated sectors where a handful of giants do most of the work.
The Technology sample reads like a roll call of the obvious: Apple, Microsoft, and NVIDIA anchor the megacaps, with AMD, Salesforce, and Intel rounding out the semiconductor-and-software spine that most portfolios lean on.
When count and capital disagree
Here the picture turns counterintuitive. Ranked by aggregate tracked market capitalisation, the order inverts. Financials lead at about $159T, Energy follows near $107T, and Basic Materials sits around $47T — despite Basic Materials carrying only 333 names. Technology's enormous roster aggregates to roughly $23T, below both. Industrials come in near $12T, Communication Services $5T, Healthcare $4T, and Consumer Cyclical a striking $0.58T on 168 companies.
That last figure is the tell. Consumer Cyclical houses Amazon, Tesla, Home Depot, and Alibaba, yet aggregates to the smallest cap of any sector — a sign these totals are not clean, comparable market caps so much as a sum of whatever the feed carries, warts and all.
Read the sample names as a warning label
The sample names make the data-quality story explicit. Tesla appears three times (TSLA, TL0.F, TL0.DE), Alphabet twice (GOOGL, GOOG), Novo Resources twice across Toronto and Australia (NVO.TO, NVO.AX), Obsidian Energy twice (OBE, OBE.TO), and Galantas Gold twice (GAL.V, GAL.L). Cross-listings inflate both the company counts and — where caps are double-booked — the sector totals. The non-US tickers (Xiamen Solex, Tencent's 0700.HK, Reliance on the NSE, Oberbank on Frankfurt) confirm this is a genuinely global, multi-exchange universe rather than a tidy single-market index.
What an investor might watch
- Technology breadth vs. concentration. With 634 names, the sector offers diversification on paper, but the familiar megacaps still define its direction. Breadth beneath Apple, Microsoft, and NVIDIA is worth tracking.
- The cap-weight heavyweights. Financials (JPMorgan, Visa, Mastercard, Berkshire) and Energy (Exxon, Shell, Reliance) carry outsized aggregate weight. Moves there matter more than their modest name counts suggest.
- Data hygiene before conclusions. Before reading too much into any single sector total, dedupe cross-listings. The Consumer Cyclical anomaly is a reminder that aggregate figures here reflect coverage quirks as much as real capital.
The headline is simple: this is a tech-dominated universe by population, but a materials-, energy-, and finance-weighted one by the numbers the feed reports — and those numbers deserve a sceptical second look before they drive a decision.
