A Universe of 672 Companies Across Eight Sectors
As of June 8, 2026, the Headmars tracked universe spans 672 companies across eight sectors, carrying a combined market capitalisation of roughly $30.5 trillion. The distribution is anything but uniform — two sectors alone account for nearly three-quarters of total tracked value.
Technology: The Undisputed Anchor
Technology commands 225 companies — one in three names in the universe — and an aggregate market cap of $17.1 trillion, representing approximately 56% of total tracked value. The sample roster tells the story: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel are household names, but the sector runs 219 names deeper. For any portfolio tracking platform, this sector is simultaneously the most rewarding to cover and the hardest to escape. Even a notionally diversified allocation ends up heavily shaped by large-cap tech dynamics.
What to watch: NVIDIA's role in AI infrastructure and AMD's competing roadmap are the most closely followed catalysts. Salesforce reflects enterprise software sentiment. Intel remains a multi-year turnaround story capable of whipsawing legacy-semiconductor corners of the sector.
Communication Services: Fewer Names, Outsized Weight
With only 27 companies, Communication Services punches well above its count — $5.2 trillion in aggregate cap, or roughly 17% of the tracked total. Alphabet (tracked as both GOOGL and GOOG), Meta, Netflix, Disney, and Tencent sit here. The sector blends advertising duopolies, streaming incumbents, and social platforms into a single bucket that correlates tightly with digital-ad cycles and AI-driven search disruption.
What to watch: Alphabet and Meta together anchor the majority of this sector's weight. Any shift in digital-ad spend, platform regulation, or AI-powered search substitution moves this sector fast.
Healthcare: Breadth Without Proportional Depth
Healthcare is the second-largest sector by company count — 151 names — yet third in aggregate market cap at $3.2 trillion. Its lower per-name average reflects a long tail of international biotechs and regional pharma names sitting alongside Johnson & Johnson, AbbVie, and UnitedHealth. That breadth creates asymmetric opportunity but also noise: a handful of managed-care and pharma giants anchor the sector while dozens of speculative names introduce binary event risk around trial readouts and regulatory decisions.
Industrials, Energy, and Financials: The Middle Tier
Industrials (101 companies, $2.4T), Energy (42 companies, $1.5T), and Financials (42 companies, $606B) form a substantial middle tier. Energy's representation is notably global — Shell, Reliance Industries, and Obsidian Energy sit alongside Exxon Mobil and Antero Resources, spanning London, Mumbai, Toronto, and New York. Financials features Berkshire Hathaway, JPMorgan, and the payments duopoly of Visa and Mastercard. Industrials ranges from Honeywell and nVent Electric to Archer Aviation and ZIM Integrated Shipping, underscoring genuine sector diversity within that bucket.
Consumer Sectors: Cyclical vs. Defensive
Consumer Cyclical (57 names, $390B) includes Amazon and Tesla — two of the most volatile large-caps in global equities — alongside Alibaba and Home Depot. Consumer Defensive (27 names, $41B) anchors the universe with Walmart, Procter & Gamble, Coca-Cola, PepsiCo, Costco, and Nestlé: low-volatility compounders that tend to act as ballast in turbulent markets.
Portfolio Implications
The concentration is stark: Technology and Communication Services together account for nearly 73% of tracked market cap across fewer than 38% of all names. Investors using Headmars should expect cap-weighted and equal-weighted performance metrics to diverge significantly. Sector filters, per-sector benchmarks, and explicit weighting controls are essential tools for navigating this universe without being blinded by tech gravity.
