The tracked universe spans 2,270 companies across eight sectors as of 10 September 2026. Two questions are worth asking of any coverage list: what dominates by breadth, and what dominates by weight? Here those two lenses disagree sharply — and the disagreement is itself the story.
Breadth: a tech-heavy list
By company count, Technology leads decisively with 612 names, roughly 27% of the universe. Industrials follow at 437, then Healthcare at 374 and Basic Materials at 320. Together those four sectors account for about 77% of everything tracked. The long tail is thinner: Consumer Cyclical (165), Financials (137), Energy (136), and Communication Services (89) round out the list.
The headline names are the ones you would expect. Technology anchors on AAPL, MSFT, NVDA, with AMD, CRM, and INTC alongside. Communication Services is compact but concentrated — GOOGL, META, NFLX, DIS, and Tencent (0700.HK). Financials leans on BRK.B, JPM, V, MA, and BAC; Consumer Cyclical on AMZN, TSLA, and HD.
The cap figures don't line up
Here is where an analyst has to be honest. The reported total market caps invert the count ranking in ways that strain belief. Financials is listed at roughly $159 trillion and Energy at $107 trillion, while Technology — the sector holding Apple, Microsoft, and NVIDIA — comes in at just $22.7 trillion. Consumer Cyclical, home to AMZN and TSLA, shows a mere $576 billion.
Those numbers are internally inconsistent. A sector carrying three of the world's largest companies cannot plausibly sit below sectors of far smaller aggregate heft. The most likely culprits are visible in the data itself: the universe is riddled with cross-listings and duplicates — TSLA appearing as TL0.F and TL0.DE, GOOGL beside GOOG, NVO.TO and NVO.AX, OBE and OBE.TO, GAL.V and GAL.L. Mixed reporting currencies across these venues, double-counted or mis-scaled, would inflate some sector totals while starving others.
What to watch
First, treat the cap column as unverified until the cross-listing and currency handling is reconciled — count is trustworthy here; weight is not. Deduplicating multi-exchange entries should be step one before any cap-weighted view is published.
Second, note the geographic spread hiding in the samples: mainland China (603992.SS, 603207.SS), Taiwan (4588.TW), Korea (187660.KQ), Hong Kong, and India (RELIANCE.NS) all appear. This is not a US-only list, which matters for how sector concentration should be interpreted.
The practical takeaway: the universe is broad and genuinely tech-tilted by breadth, but any narrative built on the current market-cap totals should wait for a clean pass on duplicates and currency normalisation.
