The shape of the universe
As of 16 July 2026, the tracked universe spans eight sectors and about 1,421 companies. The distribution is top-heavy: Technology alone contributes 482 names (~34%), followed by Industrials (330, ~23%) and Healthcare (274, ~19%). Together those three cover roughly 76% of everything we track. The remaining five sectors — Basic Materials (165), Consumer Cyclical (126), Financials (93), Energy (88), and Communication Services (63) — form a long, thinning tail.
That ordering matters. Coverage by count is a decent proxy for where investor attention concentrates, and the pecking order here mirrors the megacap-tech era: Apple, Microsoft, and NVIDIA anchor a Technology block that dwarfs every other sector by headcount.
Notable names, sector by sector
The sample rosters read like a map of modern markets. Technology carries the semiconductor and software heavyweights — AAPL, MSFT, NVDA, AMD, INTC, CRM. Communication Services is small by count (63) but dense with influence: GOOGL, META, NFLX, DIS, and Tencent all sit here. Healthcare leans on defensive giants JNJ, UNH, and ABBV, while Industrials mixes classic names like Honeywell with newer bets such as Archer Aviation (ACHR) and shipping's ZIM. Financials, though only 93 names, includes Berkshire, JPMorgan, Visa, and Mastercard.
A caution on the market-cap column
Here the data demands skepticism. The reported sector market caps are wildly inconsistent with the names inside them: Consumer Cyclical — home to Amazon and Tesla — shows a total of only ~$540B, while Financials and Energy report figures north of $100 trillion apiece. Those numbers are not credible; they almost certainly reflect FX, share-count, or aggregation errors rather than real valuation. When the dollar column and the constituent list disagree this loudly, trust the constituents. For now, company counts are the more reliable lens on this dataset.
Duplicates inflate the tail
A second wrinkle: cross-listings pad the counts. We see the same underlying business appear multiple times — Tesla as TL0.F and TL0.DE, Alphabet as GOOGL and GOOG, Obsidian Energy as OBE and OBE.TO, and Galantas Gold as GAL.V and GAL.L. This is especially visible in Basic Materials and Energy, where thin single-name coverage means each duplicate meaningfully skews the sector's apparent breadth.
What an investor might watch
Three things. First, concentration risk: a universe this Technology-weighted rises and falls with a handful of megacaps. Second, the smaller sectors — Financials, Energy, and Communication Services carry outsized real-world weight relative to their slim counts, so their few names deserve individual attention rather than sector-average thinking. Third, data hygiene: before acting on any aggregate here, reconcile the market-cap figures and de-duplicate cross-listings. The composition story is clear; the valuation story, in this snapshot, is not yet trustworthy.
