As of 15 September 2026, the tracked universe spans 2,285 companies across eight sectors. Two different lenses — how many names each sector contributes, and how much market cap it reports — point in almost opposite directions. That divergence is the most interesting thing in the data.
Composition by headcount
By company count, the universe is unmistakably tech-tilted:
| Sector | Companies | Share |
|---|---|---|
| Technology | 618 | ~27% |
| Industrials | 439 | ~19% |
| Healthcare | 377 | ~16% |
| Basic Materials | 322 | ~14% |
| Consumer Cyclical | 165 | ~7% |
| Energy | 138 | ~6% |
| Financials | 137 | ~6% |
| Communication Services | 89 | ~4% |
Technology, Industrials, Healthcare and Basic Materials together account for roughly three-quarters of all tracked names. The anchors are familiar — Apple, Microsoft and NVIDIA in Technology; Honeywell in Industrials; Johnson & Johnson and UnitedHealth in Healthcare — but the long tail reaches well beyond US megacaps, with listings such as Xiamen Solex, Tencent (0700.HK) and Reliance Industries.
The market-cap picture — read with caution
Ranked by reported market cap, the order inverts entirely. Financials ($159.5T) and Energy ($106.5T) top the table, with Basic Materials (~$47.2T) third, while Technology — the largest by count — sits fourth at ~$22.7T. Summed, the sectors report roughly $358T in aggregate market cap.
That total is a red flag. It sits well above any plausible figure for global equity value, which means the cap column is distorted, not descriptive. The sample names hint at why: the universe carries the same companies under multiple listings — Tesla appears as both TL0.F and TL0.DE, Novo Resources as NVO.TO and NVO.AX, Alphabet as both GOOG and GOOGL. Cross-listings and unit/currency mismatches inflate sector totals, and they hit commodity-heavy and dual-listed sectors like Financials, Energy and Basic Materials hardest.
The honest read: trust the headcount composition, treat the cap totals as provisional.
What an investor might watch
- Tech breadth vs. weight. The sector's dominance by count reflects coverage depth, not a call on concentration. Names span the full stack — Apple and Microsoft alongside AMD, Salesforce and Intel.
- Industrials as the second pillar. With 439 names and future-facing entrants like Archer Aviation, it is the universe's most underrated bench of ideas.
- Duplicate listings. Before drawing sector conclusions, deduplicate. The cap anomalies above are a reminder that raw totals can mislead.
Composition is a starting map, not a verdict. Here, the map's terrain (what is tracked) is solid; its elevation lines (reported cap) still need surveying.
