Where the breadth lives
As of 3 October 2026, the tracked universe spans 2,325 companies across eight sectors. Technology is the widest by a clear margin at 630 names — roughly 27% of the universe — anchored by the usual megacaps (Apple, Microsoft, NVIDIA) alongside AMD, Salesforce, and Intel. Industrials follow with 445 names and Healthcare with 381. Those top three sectors alone account for about 63% of every ticker we track, so when people say the market is a technology story, the breadth of coverage backs them up.
The tail thins quickly. Communication Services is the narrowest at just 90 names, yet it carries some of the heaviest hitters — Alphabet, Meta, Netflix, Disney, and Tencent. Fewer companies, outsized relevance: a reminder that headcount is not the same as importance.
A genuinely global sample
The sample names make clear this is not a US-only list. Chinese listings (603992.SS, 603207.SS, 1866.HK), Taiwan (4588.TW), Korea (187660.KQ), India (RELIANCE.NS), and European lines all appear. You also see the same business counted under multiple tickers — Tesla as TL0.F and TL0.DE, Alphabet as GOOGL and GOOG, Novo Resources as NVO.TO and NVO.AX, Galantas Gold as GAL.V and GAL.L. Cross-listings are normal, but they matter for the next point.
When market cap and headcount disagree
Rank the same eight sectors by the aggregate market-cap field and the order inverts entirely. The data puts Financials first (~$159.5T), Energy second ($106.6T), and Basic Materials third ($47.2T), while Technology's ~$22.7T sits mid-table and Consumer Cyclical trails at ~$0.58T — despite that sector holding Amazon and Tesla.
That ordering should not be taken at face value. The Financials and Energy totals are larger than the entire real-world global equity market, which strongly suggests an aggregation problem rather than a signal. The cross-listed duplicates noted above are a plausible culprit: counting the same company under several exchange tickers inflates a sector's apparent cap. Until that is reconciled, I would treat the company-count breakdown as the trustworthy composition metric and the aggregate cap column as a data-hygiene item, not an investment input.
What an investor might watch
- Technology concentration. With a quarter of the universe in one sector led by a handful of megacaps, moves in Apple, Microsoft, or NVIDIA will dominate any breadth-weighted read.
- The narrow-but-heavy sectors. Communication Services and Financials carry influential names in few tickers — worth watching per-name rather than in aggregate.
- Data reconciliation. The cap/headcount divergence is the clearest actionable item here: dedupe cross-listings before any market-cap weighting is trusted.
Breadth says Technology. The cap column says something implausible. For now, trust the count.
