The Headmars platform now tracks roughly 2,000 companies across eight sectors. A single snapshot of that universe is a useful thing: it tells you where breadth lives, where the marquee names cluster, and — if you read carefully — where the data itself deserves a second look.
Breadth belongs to Technology
By company count, the tracked universe leans heavily toward Technology, with 568 names — more than a quarter of everything on the platform. The sample reads like a who's-who of the sector: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel. Industrials (388) and Healthcare (332) round out the top three, together making up roughly a third of the universe. Industrials is notably eclectic, spanning Honeywell and nVent alongside newer bets like Archer Aviation and cross-listed Asian manufacturers.
The long tail thins out from there: Basic Materials (254), Consumer Cyclical (145), Energy (119), Financials (118), and Communication Services (79). That last group is small in number but heavy in influence, anchored by Alphabet, Meta, Netflix, Disney, and Tencent.
Market cap tells the opposite story
Here is where it gets interesting. Rank the sectors by reported total market cap and the order inverts almost completely. Financials leads at roughly $159T, followed by Energy ($107T) and Basic Materials ($46T). Technology, the count leader, sits fourth at $22T. Consumer Cyclical, home to Amazon and Tesla, reports the smallest total of all ($0.57T).
That divergence is a signal worth pausing on. When the sector with the most companies is not the sector with the most capital — and when a Consumer Cyclical bucket holding Amazon and Tesla ranks dead last by value — the figures are almost certainly distorted rather than descriptive.
Read the duplicates
The sample names give the game away. Tesla appears three times (TSLA, TL0.F, TL0.DE); Alphabet shows up as both GOOG and GOOGL; Novo Resources as NVO.TO and NVO.AX; Galantas Gold as GAL.V and GAL.L; Obsidian Energy as OBE and OBE.TO. Cross-listings and duplicate tickers inflate aggregate market-cap totals wherever they cluster, which is a plausible driver behind the outsized Financials, Energy, and Materials figures. The count-based view is the more trustworthy lens right now.
What an investor might watch
A few takeaways stand out:
- Concentration risk in Tech. With over a quarter of the universe in one sector, portfolio breadth here can create a false sense of diversification.
- Communication Services punches above its weight. Only 79 names, but they include some of the most-followed mega-caps on the platform.
- Trust the counts, question the caps. Until cross-listing duplicates are reconciled, treat sector market-cap rankings as directional at best.
Composition is the first thing an AI-driven platform should get right, because every downstream signal inherits its blind spots. This snapshot suggests the coverage is broad and Tech-forward — and that the next win is cleaning up the ledger.
