The shape of the universe
As of 29 September 2026, the tracked universe spans 2,313 companies across eight sectors. By headcount, the distribution is unmistakably top-heavy toward two groups. Technology leads with 624 companies, followed by Industrials at 442. Together those two sectors account for roughly 46% of every name we follow. Healthcare (381) and Basic Materials (331) form a substantial middle tier, while Communication Services (89) sits at the tail.
That ordering matters. When a universe is this concentrated in Technology and Industrials, breadth readings and equal-weight performance will be disproportionately steered by those two cohorts. A rotation out of tech is not a marginal event here — it moves a quarter of the tracked names.
Familiar anchors, unfamiliar breadth
The sample names confirm that the large, liquid megacaps are all present: Apple, Microsoft and NVIDIA anchor Technology; Alphabet, Meta and Netflix headline Communication Services; Berkshire, JPMorgan, Visa and Mastercard sit atop Financials; Exxon, Shell and Reliance lead Energy.
More interesting is the long tail. Industrials pairs Honeywell with Archer Aviation and a clutch of Chinese and Taiwanese listings (603992.SS, 4588.TW). Basic Materials leans heavily toward small-cap miners and fertiliser names across Hong Kong, Toronto, Australia and London. This is a genuinely global, small-cap-inclusive universe — not a curated megacap index.
A note on the market-cap figures
The reported sector market-cap totals deserve scepticism rather than headlines. Financials is listed at ~$159.5T, Energy at ~$106.6T and Basic Materials at ~$47.2T — each larger than Technology's ~$22.7T, despite carrying a fraction of the constituents and, in Financials' case, only 139 names. Meanwhile Consumer Cyclical shows just ~$577B even though it contains Amazon and Tesla.
Those numbers are internally inconsistent with the company counts and with what the sample names imply. The most likely culprits are duplicate cross-listings (note Tesla appearing as TL0.F and TL0.DE, Alphabet as GOOG and GOOGL, Novo Resources as both NVO.TO and NVO.AX) and unit or currency mismatches inflating a handful of tickers. For now, I would treat company count as the reliable structural signal and the cap totals as provisional.
What to watch
- Concentration risk in the count. With Technology and Industrials dominating by number, universe-wide breadth metrics will echo those sectors first.
- The small-cap materials and industrials tail. Miners, fertiliser producers and emerging aviation names bring higher volatility and thinner liquidity — useful for opportunity, demanding on risk controls.
- Data hygiene. The cap discrepancies point to cross-listing de-duplication and currency normalisation as the highest-value cleanup before any cap-weighted analysis is trustworthy.
Takeaway
Structurally, this is a broad, globally diversified universe tilted toward Technology and Industrials by count, with deep small-cap representation in Materials. The composition is sound; the market-cap accounting is not yet ready to lean on. Fix the duplicates, and the sector picture sharpens considerably.
