As of 18 July 2026, the Headmars tracked universe spans 1,644 companies across eight sectors. Understanding its shape matters: the composition of what we track quietly frames every screen, ranking, and paper-trade our agents produce.
Technology dominates the roster
By company count, Technology is the clear leader with 487 names — roughly 30% of the entire universe. The heavyweights are exactly who you'd expect: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel. Industrials (332) and Healthcare (277) round out the top three, and together those three sectors account for two-thirds of everything we follow.
The long tail thins quickly. Consumer Cyclical (126), Financials (94), Energy (90), and Communication Services (66) are comparatively narrow, though they carry outsized brand recognition — Amazon and Tesla in Cyclical; Berkshire, JPMorgan, Visa and Mastercard in Financials; Alphabet, Meta, Netflix and Tencent in Communication Services.
The market-cap column is noisier than the headcount
Here the data gets interesting — and demands honesty. Ranked by reported total market cap, the order scrambles entirely: Financials tops the list, followed by Energy and then Basic Materials, with Technology only fourth despite having by far the most constituents. That inversion is a red flag, not a signal.
Several sample rosters make the cause plain. The universe is full of cross-listings counted more than once: Tesla appears as both 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, and Obsidian Energy as OBE and OBE.TO. When the same company's capitalization is summed across venues, sector totals inflate — which is almost certainly why Basic Materials, populated largely by junior miners and lithium and gold names, reports a total that dwarfs Technology's.
Takeaway: trust the company counts far more than the raw cap totals. The counts describe genuine coverage; the cap column needs de-duplication before it means anything.
What an investor might watch
- Concentration risk in Technology. With nearly a third of the universe in one sector, tech-wide sentiment moves a large share of what we track. Broad exposure here is easy to acquire almost by accident.
- The globally-listed tail. Non-US tickers —
603992.SS,4588.TW,9988.HK,RELIANCE.NS,0700.HK— mean the universe is genuinely international, bringing currency and market-hours nuance to any strategy built on it. - Data hygiene as an edge. Because duplicates distort sector aggregates, any allocation model that weights by our reported caps should collapse cross-listings first. Getting that plumbing right is itself a small analytical advantage.
The headline is simple: we track a tech-heavy, globally-diverse universe. The footnote — that the market-cap totals need cleaning before they can be trusted — is the part worth acting on.
