Where the names live
The Headmars tracked universe currently spans 1,846 companies across eight sectors, and the concentration is hard to miss. Technology leads with 531 names (about 29% of everything we follow), anchored by the usual megacaps — AAPL, MSFT, and NVDA — alongside the semiconductor and software cohort of AMD, INTC, and CRM.
The next two tiers give the universe its shape:
- Industrials — 361 companies, a genuinely global mix from Honeywell (HON) and nVent (NVT) to shipping (ZIM), eVTOL upstart Archer Aviation (ACHR), and Asian names like Xiamen Solex and Arch Meter.
- Healthcare — 310 companies, led by JNJ, UNH, and ABBV, but with a long tail reaching into Chinese and Korean small-cap pharma.
Together, those three sectors make up roughly 65% of the tracked list. Basic Materials (220) rounds out the heavyweight group, heavy on miners and fertilizer producers.
The thinner sectors
The remaining four sectors are, by count, comparatively lean: Consumer Cyclical (138), Financials (109), Energy (104), and Communication Services (73). Don't mistake small counts for small importance — these buckets hold some of the most-watched tickers anywhere. Communication Services is only 73 names but contains GOOGL, META, NFLX, DIS, and Tencent; Financials packs BRK.B, JPM, V, MA, and BAC into just over a hundred slots.
A note on the market-cap figures
Here's where a good analyst should slow down. The per-sector market-cap totals in this snapshot don't square with the company lists. Consumer Cyclical — which includes Amazon, Tesla, Home Depot, and Alibaba — is reported at only ~$556B, while Financials is reported north of $159 trillion. Those numbers are internally inconsistent with the names attached to them, so I'd treat this snapshot's cap totals as unreliable and lean on company counts instead until the aggregation is audited.
A likely culprit is visible right in the sample data: cross-listings and duplicates. Tesla shows up as TSLA, TL0.F, and TL0.DE; Alphabet as both GOOG and GOOGL; Novo Resources across .TO and .AX; Galantas Gold across .V and .L. Counting a company once per exchange inflates both name counts and any naive cap sum.
What an investor might watch
Three things stand out from the composition alone:
- Tech concentration. With nearly a third of tracked names in one sector, the universe's mood will move with semis and software. Diversification across the list is thinner than the raw count suggests.
- Industrials as the breadth play. Its global, multi-theme roster — aerospace, shipping, electrification, metering — makes it a useful read on real-economy sentiment.
- Data hygiene. Before drawing any weighting or valuation conclusion, de-duplicate cross-listings and reconcile the cap totals. On this snapshot, counts are trustworthy; the dollar figures are not.
Composition tells you where attention is pooled. Right now, it's pooled in Technology — and the price tags need a second look.
