The shape of the universe
Headmars currently tracks 1,674 companies across eight sectors, and their distribution is anything but even. Technology alone contributes 496 names — roughly 30% of the entire universe. Add Industrials (336) and Healthcare (282) and you have 1,114 companies, or about two-thirds of everything we follow. The remaining five sectors — Basic Materials (176), Consumer Cyclical (128), Financials (97), Energy (91), and Communication Services (68) — split the last third between them.
That skew matters. When a third of your tracked names live in one sector, sector-level news — a chip cycle, a rate move that repriced growth multiples — ripples through a disproportionate slice of the coverage.
The familiar mega-caps
The sample names read like a who's-who of index heavyweights. Technology anchors on Apple, Microsoft, and NVIDIA, with AMD, Salesforce, and Intel close behind. Communication Services is thin on count (68) but heavy on gravity: Alphabet, Meta, Netflix, Disney, and Tencent. Financials leans on Berkshire Hathaway, JPMorgan, Visa, and Mastercard; Energy on Exxon, Shell, and Reliance; Healthcare on Johnson & Johnson, UnitedHealth, and AbbVie. Consumer Cyclical is small by count but headlined by Amazon and Tesla.
Alongside the giants sit far more speculative tickers — Archer Aviation in eVTOL, Argentina Lithium & Energy, and a scattering of small-cap gold miners in Basic Materials. The universe spans the full risk spectrum, not just the blue chips.
A genuinely global list
The tickers make clear this is not a US-only universe. We see Shanghai (603992.SS), Hong Kong (1866.HK, 0700.HK, 9988.HK), Taiwan (4588.TW), Korea (187660.KQ), India (RELIANCE.NS), and Frankfurt (OBK.F) listings throughout. For an investor, that breadth is a feature — but it also introduces currency and duplicate-listing complications.
A caution on the cap totals
The per-sector market-cap totals should be read with suspicion, not confidence. Financials shows a total that dwarfs every other sector despite having just 97 names, and Basic Materials and Energy both outrank Technology on aggregate cap — which the individual names do not support. The likely culprit is visible right in the data: cross-listed duplicates. 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. Double-counting the same company across venues inflates the totals. Until those duplicates are reconciled, company counts are the more trustworthy lens.
What to watch
Three things. First, Technology's concentration — any sector-wide re-rating moves a large share of coverage. Second, Industrials' surprising breadth, spanning defense-grade names like Honeywell to early-stage aviation. Third, the cross-listing noise: clean the duplicates before trusting any aggregate valuation figure. Breadth tells the honest story here; the dollar totals still need scrubbing.
