As of 15 July 2026, the Headmars universe spans 1,603 tracked companies across eight sectors. Composition is a quieter signal than price, but it tells you where a platform's attention — and by extension its users' — is concentrated. The headline is unambiguous: this is a tech-heavy dataset with a broad industrial and healthcare middle.
Technology sets the pace
Technology alone accounts for 481 companies, roughly 30% of the entire universe. The sample names are the usual megacap anchors — Apple, Microsoft, and NVIDIA — alongside the semiconductor and software supporting cast of AMD, Intel, and Salesforce. No other sector comes close on count. When a single category holds three of every ten tracked tickers, sector-level moves in tech will disproportionately shape whatever aggregate views users build on top of this data.
The industrial and healthcare middle
Beneath tech sits a substantial mid-tier. Industrials contribute 327 names (about 20%), spanning Honeywell and nVent alongside newer-economy entrants like Archer Aviation and a notable set of Chinese and Taiwanese listings. Healthcare adds 269 companies — Johnson & Johnson, UnitedHealth, and AbbVie among the anchors. Together, Industrials and Healthcare make up more than a third of the universe, which is healthy: breadth here means users aren't forced into a purely large-cap-tech lens.
The smaller sectors round things out: Basic Materials (161), Consumer Cyclical (126, led by Amazon and Tesla), Financials (90, anchored by Berkshire, JPMorgan, Visa, and Mastercard), Energy (87), and Communication Services (62, home to Alphabet, Meta, and Netflix).
Read the market-cap column with caution
One thing worth flagging honestly: the aggregate totalMarketCapM figures do not line up with intuition. Consumer Cyclical — which includes Amazon and Tesla — reports roughly 540 billion, while Basic Materials, Financials, and Energy each report figures many times larger than Technology's. That ordering is implausible for a universe fronted by the names listed, and the presence of duplicate cross-listings (multiple Tesla, Novo Resources, and Galantas Gold tickers across exchanges) points to double-counting or currency-mixing in the totals. My read: trust the company counts as a clean breadth signal, and treat the market-cap aggregates as a data-quality item to reconcile before anyone leans on them.
What an investor might watch
First, concentration risk in the lens itself: with tech at 30% of tracked names, sector rotation out of technology would thin coverage exactly where most eyes are. Second, the emerging-industrial cohort — names like Archer Aviation sitting beside legacy Honeywell — is where new secular themes tend to surface first. Third, and most practically, the cross-listing duplication suggests dashboards should de-duplicate by underlying entity before aggregating anything.
Breadth is a feature here — eight sectors, a real mid-tier, global listings. The next win is cleaning the aggregates so the numbers earn the same trust the counts already do.
