The shape of the board
As of 23 August 2026, the tracked universe spans 2,091 companies across eight sectors. Sorted by headcount, the ranking is unsurprising: Technology dominates with 582 names — more than a quarter of everything we follow — trailed by Industrials (405) and Healthcare (348). At the thin end sit Communication Services (82), Financials (122), and Energy (124).
That breadth ranking is the one most investors carry in their heads. It is also, on this data, misleading.
When you weigh instead of count
Re-sort by total tracked market capitalisation and the podium changes entirely. Financials lead at roughly $159T, followed by Energy ($107T) and Basic Materials ($47T). Technology, the runaway leader by name count, ranks fourth by weight at ~$23T. Consumer Cyclical, despite housing Amazon and Tesla, carries the smallest aggregate at ~$0.6T.
The lesson is an old one worth repeating: the number of tickers in a sector tells you almost nothing about the capital concentrated there. A universe can be broad in one dimension and top-heavy in a completely different one. An index built on equal-weighting our names would be a tech-and-industrials bet; one built on cap-weighting would be a financials-and-energy bet. Same universe, opposite exposures.
Notable names, and a global tilt
The marquee constituents are what you would expect — Apple, Microsoft and NVIDIA anchoring Technology; JPMorgan, Visa and Berkshire in Financials; Exxon and Shell in Energy; Alphabet and Meta in Communication Services. But the sample names also reveal a genuinely international book: Xiamen Solex and Shanghai Xiao Fang in China, Reliance Industries in India, Tencent and Alibaba in Hong Kong, and a scattering of Korean, Australian and Canadian listings. This is not an S&P 500 mirror.
A caveat worth flagging
The cap figures deserve a skeptic's eye. The sample names show the same company listed more than once across venues — NVO.TO and NVO.AX, GAL.V and GAL.L, OBE and OBE.TO, TL0.F and TL0.DE, GOOG and GOOGL. Where dual and cross-listings are counted separately, aggregate market cap can be double-counted, inflating the heavier sectors. Materials and Financials, both rich in cross-listed miners and banks, are the likeliest to be overstated. Treat the cap totals as directional, not precise.
What an investor might watch
- The breadth-vs-weight gap. If you screen our universe, decide up front whether you want the many (Technology) or the heavy (Financials, Energy).
- Concentration in the thin sectors. Consumer Cyclical carries big brands but a tiny aggregate — a sign its weight sits in very few names.
- Listing hygiene. Before trusting any sector-cap comparison, confirm whether cross-listed duplicates have been collapsed.
The universe is broad, global, and — once you look past the headcount — far less tech-dominated than a first glance suggests.
