A universe built on breadth
Headmars tracks 2,357 companies across eight sectors, and the distribution is unmistakably tech-led. Technology alone accounts for 642 names — about 27% of the universe — followed by Industrials (449), Healthcare (388) and Basic Materials (335). Those four sectors together make up roughly 77% of everything we track. The tail is thin by comparison: Communication Services (91) and Energy (141) are the least-represented by headcount.
The names behind the numbers
The sector leaders read as you'd expect. Technology anchors on Apple, Microsoft and NVIDIA, with AMD, Salesforce and Intel close behind. Communication Services is small but heavyweight — Alphabet, Meta, Netflix, Disney and Tencent. Financials leans on Berkshire Hathaway, JPMorgan, Visa and Mastercard. What's striking is how international and long-tailed the roster gets past the megacaps: Xiamen Solex, Arch Meter, PenetriumBio and a string of micro-cap miners sit alongside the household names. This is a global, deep universe, not an S&P 500 mirror.
When cap and count disagree
The market-cap aggregates tell a different — and stranger — story than the headcount. By total tracked cap, Financials lead at roughly $159T, Energy at $107T and Basic Materials at $47T, pushing Technology down to fourth at about $23T. That ordering should raise an eyebrow. Summed across all sectors, the tracked cap comes to roughly $358T — larger than the entire global equity market. Consumer Cyclical, meanwhile, shows just $0.58T despite containing both Amazon and Tesla.
The likely culprit is visible in the sample names: duplicate cross-listings. Novo Resources appears as both NVO.TO and NVO.AX; Galantas Gold as GAL.V and GAL.L; Obsidian Energy as OBE and OBE.TO; Tesla as TL0.F and TL0.DE; Alphabet as GOOG and GOOGL. Each duplicate inflates or distorts the sector totals. Of the two views, the count-based picture is the more trustworthy.
What an investor might watch
Two things. First, concentration: with Technology and Industrials supplying nearly half the universe by name, breadth screens and sector-rotation signals will be dominated by those two buckets — worth normalizing for. Second, data hygiene: before trusting any cap-weighted aggregate, the cross-listing duplicates need deduping and the implausible totals investigating. Until then, treat headcount as the reliable lens on this universe, and the cap column as a work in progress.
