Every portfolio platform is shaped by the universe it watches. Today the Headmars tracked set spans eight sectors and roughly 2,226 companies, and the way those names distribute tells you as much about market structure as about any single ticker.
Technology leads on breadth
By company count, Technology is the clear heavyweight at 602 names — about 27% of the universe — anchored by the usual megacaps: Apple, Microsoft, and NVIDIA, alongside AMD, Salesforce, and Intel. Industrials follows with 429 companies (~19%), a genuinely global mix that runs from Honeywell and nVent to Archer Aviation, shipping operator ZIM, and Chinese and Taiwanese names like Xiamen Solex and Arch Meter. Healthcare rounds out the top three with 369 names (~17%), spanning defensives such as Johnson & Johnson, UnitedHealth, and AbbVie down to smaller specialists like GoodRx.
Basic Materials is deeper than many would guess at 311 companies (~14%), heavily populated with miners and fertiliser producers — China XLX, Argentina Lithium, Galantas Gold. The long tail — Consumer Cyclical (164), Financials (135), Energy (129), and Communication Services (87) — is smaller by count but carries recognisable anchors: Amazon and Tesla; Berkshire, JPMorgan, Visa, and Mastercard; Exxon, Shell, and Reliance; Alphabet, Meta, and Netflix.
A market-cap column to distrust
Here the data demands honesty. The reported aggregate market caps do not survive a sniff test. Consumer Cyclical — which contains Amazon, Tesla, Home Depot, and Alibaba — shows just $575bn, while Financials reports $47tn) are similarly implausible. These totals almost certainly reflect mixed currencies and double-counted listings rather than real capitalisation, so I would not build any allocation view on them. The company-count distribution is the trustworthy structural signal for now.$159tn, a figure larger than global GDP. Energy ($107tn) and Basic Materials (
The cross-listing tax
The sample names expose a second data-quality theme: duplication. Tesla appears as TL0.F and TL0.DE; Alphabet as both GOOG and GOOGL; Novo Resources as NVO.TO and NVO.AX; Galantas as GAL.V and GAL.L; Obsidian Energy as OBE and OBE.TO. Cross-listings inflate raw counts and, if not deduplicated, quietly distort any market-cap roll-up — a plausible partial explanation for the figures above.
What an investor might watch
Three things stand out. First, the tech and industrials tilt means the universe is sensitive to the capex and rate cycles those sectors ride. Second, the depth in Basic Materials and Energy — miners, lithium, fertiliser, oil — gives the set real commodity exposure that a US-megacap-only lens would miss. Third, and most practically: treat the sector aggregates as a breadth map, not a valuation map, until the currency normalisation and cross-listing dedup are fixed. Clean data first; conclusions second.
