The shape of the tracked universe
Headmars currently follows 1,879 companies spread across eight sectors, and the distribution is anything but even. Technology alone accounts for 540 names — roughly 29% of the entire tracked universe — followed by Industrials at 366 and Healthcare at 315. Those three sectors together represent about 65% of everything we watch. Basic Materials (226) fills out the top four before the roster thins sharply: Consumer Cyclical (138), Financials (113), Energy (106), and Communication Services (75) round out the tail.
Breadth, in other words, clusters where innovation and industrial activity are most fragmented. Technology and Industrials host a long tail of smaller listings — from Apple, Microsoft, and NVIDIA down to names like Archer Aviation and nVent — while Communication Services is a concentrated club of giants.
The anchors in each sector
Each sector is defined less by its count than by the megacaps that anchor it. Technology leans on AAPL, MSFT, and NVDA, with AMD, Salesforce, and Intel rounding out the semiconductor-and-software core. Communication Services, despite being the smallest by count, carries some of the heaviest names on the platform: Alphabet (tracked twice, as GOOGL and GOOG), Meta, Netflix, Disney, and Tencent. Financials is headlined by Berkshire Hathaway, JPMorgan, Visa, and Mastercard; Consumer Cyclical by Amazon and Tesla; Energy by Exxon, Shell, and Reliance.
A caveat on the market-cap column
Here is where a market analyst has to be candid: the aggregate market-cap figures in this dataset do not pass a smell test. Financials reports roughly $159T, Energy $106T, and Basic Materials $46T — each dwarfing Technology's $22T despite carrying a fraction of the companies. Given that global equity market capitalization sits near $100–120T in total, no single sector can plausibly clear $150T.
The sample names hint at why: the universe is riddled with cross-listings and duplicates. Novo Resources appears as both NVO.TO and NVO.AX, Galantas Gold as GAL.V and GAL.L, Tesla as TL0.F and TL0.DE, Obsidian Energy as OBE and OBE.TO. When the same underlying company is counted several times across exchanges — sometimes with mismatched or unconverted currencies — aggregate caps inflate fast. Treat the count column as reliable and the cap column as provisional until deduplication and FX normalization are in place.
What to watch
For investors, the takeaway is structural. The platform's coverage skews heavily toward Technology and Industrials, so sector-level signals from those groups will be statistically richer and more diversified. Thinner sectors like Communication Services are dominated by a handful of mega-caps, meaning a single name can swing the whole group. And before anyone benchmarks against these sector caps, the duplicate-listing problem is the first thing worth cleaning up — good analysis starts with trustworthy denominators.
