The shape of the tracked universe
As of 31 July 2026, the Headmars universe spans 1,809 companies across eight sectors. Sorted by count, the hierarchy is unambiguous:
| Sector | Companies | Share |
|---|---|---|
| Technology | 525 | ~29% |
| Industrials | 358 | ~20% |
| Healthcare | 305 | ~17% |
| Basic Materials | 204 | ~11% |
| Consumer Cyclical | 136 | ~8% |
| Financials | 107 | ~6% |
| Energy | 101 | ~6% |
| Communication Services | 73 | ~4% |
The top three sectors alone — Technology, Industrials, and Healthcare — make up roughly two-thirds of every name we follow. That is a portfolio-tracker skewed toward where investor attention actually lives.
Technology leads, but Industrials is the quiet story
Technology's 525 companies is no surprise: the sample reads like the modern index itself — Apple, Microsoft, NVIDIA, AMD, Salesforce, Intel. What's more interesting is the 358-name Industrials cohort. Alongside familiar large caps like Honeywell and nVent, it reaches into aviation upstarts such as Archer Aviation and deeply international listings like Xiamen Solex and Arch Meter in Taiwan. Breadth, not just marquee names, defines this sector.
Healthcare (305) blends defensive giants — Johnson & Johnson, UnitedHealth, AbbVie — with smaller and overseas biotechs. The result is a sector that offers both ballast and speculative optionality within a single label.
A word of caution on the market-cap totals
The aggregate market-cap figures deserve skepticism rather than headlines. Financials reports a total of roughly $159 trillion and Basic Materials about $46 trillion — implausibly large — while Consumer Cyclical shows only ~$547 billion despite containing Amazon and Tesla. These numbers do not reconcile with reality, and the sample names hint at why: the universe is riddled with cross-listings and duplicates.
Look at the evidence in the data itself. Alphabet appears as both GOOGL and GOOG. Tesla shows up as TL0.F and TL0.DE. Novo Resources is listed as NVO.TO and NVO.AX; Galantas Gold as GAL.V and GAL.L; Obsidian Energy as OBE and OBE.TO. When the same underlying company is counted several times across venues, both the company counts and any naive market-cap sum inflate. The aggregate cap totals here are best read as artifacts, not truth.
What an investor might watch
- Concentration risk in the tracked set. With ~29% of names in Technology, sentiment shifts in a handful of mega-caps can dominate the mood of the whole board.
- Under-covered defensives. Financials and Energy carry only ~6% of names each, despite housing Berkshire Hathaway, JPMorgan, Visa, Exxon, and Shell. Thin coverage of low-volatility sectors is worth noting for anyone leaning defensive.
- International breadth. Listings from Hong Kong, Shanghai, Taiwan, Toronto, and Sydney mean currency and venue matter as much as the sector label.
The takeaway
By count, the universe tilts hard toward Technology, Industrials, and Healthcare — a reasonable mirror of where retail and institutional interest cluster. But the market-cap columns are a reminder that data hygiene, not just data volume, drives good analysis. Deduplicating cross-listings is the first thing we'd fix before trusting any weighted view of this universe.
