The shape of the universe
As of 1 October 2026, the Headmars tracked universe spans eight sectors and roughly 2,319 companies. Breadth is heavily skewed toward a handful of sectors. Technology leads decisively with 626 companies, followed by Industrials (444), Healthcare (381), and Basic Materials (332). The long tail thins out quickly: Consumer Cyclical (167), Energy (140), Financials (139), and Communication Services (90) together account for well under a third of the names we follow.
Measured purely by how many companies we track, this is a tech- and industrials-weighted lens on the market. Nearly half of all tracked tickers sit in the top three sectors.
The marquee names
The sample names are a useful reminder of what anchors each sector. Technology is led by familiar megacaps — Apple, Microsoft, and NVIDIA — alongside AMD, Salesforce, and Intel. Communication Services is a compact but concentrated group: Alphabet, Meta, Disney, Netflix, and Tencent. Financials leans on Berkshire Hathaway, JPMorgan, Visa, Mastercard, and Bank of America, while Consumer Cyclical is headlined by Amazon, Tesla, and Home Depot.
Industrials and Basic Materials tell a different story. Their rosters skew toward smaller, internationally listed names — Xiamen Solex, ZIM Integrated Shipping, Archer Aviation, and a scattering of lithium and gold miners such as Argentina Lithium and Galantas Gold. These sectors carry breadth but not necessarily household recognition.
A note on the market-cap figures
An honest read of the data requires flagging something: the reported total market caps do not line up with company counts in an intuitive way. Energy, Financials, and Basic Materials show far larger aggregate totals than Technology, despite Technology having several times more constituents and the better-known megacaps. These figures look likely to be affected by currency mixing, duplicate cross-listings, or unit inconsistencies, so we would not lean on them for sector weighting today.
The duplicate-listing issue is visible in the raw names. Tesla appears as TL0.F and TL0.DE, Novo Resources as both .TO and .AX lines, Obsidian Energy as OBE and OBE.TO, Galantas as GAL.V and GAL.L, and Alphabet as GOOGL and GOOG. Any naive aggregation that treats these as distinct entities will inflate both counts and caps.
What to watch
For an investor using this universe, three things stand out. First, concentration of attention: the tech and industrials tilt means the platform's coverage mirrors where listing activity is densest, not necessarily where returns concentrate. Second, cross-listing hygiene — deduplicating multi-exchange lines matters before drawing any breadth or weighting conclusions. Third, data provenance on market cap — until the aggregate figures reconcile with constituent counts, treat company count as the more reliable signal of coverage. Breadth is real; the cap totals deserve a second look before they drive a decision.
