The Universe at a Glance
As of July 8, 2026, the Headmars tracked universe spans 1,509 companies across eight sectors, ranging from household mega-caps to micro-cap explorers listed on exchanges from New York to Hong Kong to Toronto. The breadth is intentional — a portfolio tracker is only as useful as its coverage.
But breadth masks concentration. Technology alone accounts for 462 names, nearly a third of the entire universe. And when you look at aggregate market cap, the picture gets more interesting — and more counterintuitive.
Technology: The Anchor
With 462 companies and a combined market cap of roughly $21.1 trillion, Technology is the undisputed anchor of the tracked universe. Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel are among its most-watched names — a cohort that touches semiconductors, cloud infrastructure, enterprise software, and consumer devices simultaneously.
For investors, this sector warrants close attention to a few key dynamics: AI chip demand (NVIDIA, AMD), platform consolidation in enterprise software (CRM), and the ongoing recovery narrative at Intel. Any macro shift in capital expenditure on data centers will ripple across multiple names here.
The Market-Cap Surprises
Two sectors demand a second look when you compare company count to aggregate market cap:
Basic Materials lists only 138 companies — fewer than Healthcare or Industrials — yet carries a stated aggregate market cap of $44.2 trillion, the highest of any sector in this dataset. That figure is heavily influenced by multi-exchange listings (the same underlying company appearing under different tickers in Hong Kong, Toronto, and Australian markets) rather than purely independent entities. Investors should be aware that cross-listed names like Novo Resources inflate raw aggregates; the economic exposure is not additive.
Financials, with just 88 companies, logs $98.7 trillion in aggregate market cap — another figure shaped by how market caps are attributed across listings. Names like Berkshire Hathaway (BRK.B), JPMorgan Chase (JPM), Visa (V), and Mastercard (MA) are individually enormous, but the aggregate also reflects global exchange cross-listings.
The practical takeaway: aggregate market cap across this universe is best read as a relative weight signal, not an absolute valuation sum.
Mid-Tier Sectors Worth Watching
Communication Services (56 companies, ~$5.2T cap) is small by count but punches hard by name recognition: Alphabet, Meta, Netflix, Disney, and Tencent. This sector is a proxy for advertising spend, streaming subscriber economics, and AI-monetization timelines — all of which remain in flux.
Healthcare (255 companies, ~$3.5T) offers the broadest mix of risk profiles: blue-chip stalwarts like Johnson & Johnson and UnitedHealth sit alongside biotech early-stage names like PenetriumBio (KQ-listed) and Shanghai Xiao Fang Pharmaceutical. Drug pricing policy and GLP-1 competition are the macro variables to track here.
Industrials (312 companies, ~$3.4T) is the most globally diverse sector by exchange — spanning a Chinese solar manufacturer, a Taiwanese meter company, Israeli shipping (ZIM), U.S. infrastructure (Honeywell), and an eVTOL startup (Archer Aviation). The spread makes it a useful bellwether for global capex sentiment.
What to Watch
- Technology vs. Communication Services convergence: as AI features blur the line between software platforms and media, the sector boundary becomes a portfolio construction question.
- Cross-listed names in Basic Materials: investors tracking lithium or gold exposure should normalize for duplicate tickers before sizing positions.
- Energy (80 companies, ~$1.8T): the smallest cap-weighted sector proportionally, yet it includes XOM, Shell, and Reliance — names sensitive to crude price swings and energy-transition capital allocation.
The Headmars universe is built for breadth. Learning to read its shape — where the weight sits, where the dispersion lives — is the first step toward using it well.
