The Landscape at a Glance
As of 10 June 2026, the Headmars tracked universe spans 777 companies across eight sectors and multiple global exchanges — NYSE, NASDAQ, HKEX, Shanghai, Frankfurt, the TSX, and more. Combined tracked market capitalisation sits at approximately $31.7 trillion. That breadth is intentional: Headmars is built for investors who hold more than a single-country index.
But breadth does not mean balance.
Technology: The Undisputed Anchor
With 249 companies and $17.3 trillion in market cap, Technology represents roughly 54.5% of the entire tracked universe by value — despite accounting for only 32% of companies. The sector's sample names read like a who's who of modern computing: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel. The spread from mega-cap platform companies down to mid-cap chip designers gives this sector the widest valuation range of any in the universe.
For portfolio holders overweight in tech, that concentration is both an opportunity and a risk amplifier. When this sector moves, the aggregate portfolio moves.
Communication Services: Fewer Names, Enormous Weight
At just 32 companies, Communication Services is the smallest sector by count — yet it logs $5.25 trillion in market cap, good for second place overall and 16.6% of the universe. Alphabet (in both share classes), Meta, Netflix, Disney, and Tencent are enough to explain why. This is the most concentrated sector in the universe: fewer than a dozen names carry the majority of the weight.
Investors tracking names like GOOGL and META should be aware they are implicitly taking a large bet on digital advertising cycles and AI-driven monetisation.
Healthcare and Industrials: The Steady Middle
Healthcare (180 companies, $3.27 trillion) and Industrials (122 companies, $3.02 trillion) form a credible mid-tier. Healthcare's roster — Johnson & Johnson, UnitedHealth, AbbVie — anchors the sector in large-cap stability, while smaller entries like PenetriumBio and Shanghai Xiao Fang Pharmaceutic signal exposure to biotech development pipelines and emerging-market pharma.
Industrials show a similar duality: Honeywell alongside early-stage names like Archer Aviation (eVTOL) and shipping plays like ZIM. This sector rewards investors who follow capex cycles, logistics pricing, and the long arc of electrification.
Energy and Financials: Selective but Substantive
Energy (48 companies, $1.66 trillion) punches above its company count with names spanning three continents — ExxonMobil, Shell, and Reliance Industries. Smaller producers like Obsidian Energy (cross-listed on TSX and NYSE) add junior exposure. This sector is a natural hedge against inflationary regimes.
Financials (47 companies, $618 billion) is notably lean given the sector's historical market weight. Berkshire Hathaway, JPMorgan, Visa, and Mastercard are present, but the sector's relatively modest aggregate cap suggests the tracked universe skews toward growth over value — something worth factoring into any benchmark comparison.
Consumer Cyclical and Basic Materials: The Long Tail
Consumer Cyclical (68 companies, $465 billion) includes Amazon, Tesla, Home Depot, and Alibaba — names capable of outsized moves on consumer sentiment. Basic Materials is the smallest sector by both count (31 companies) and cap ($112 billion), populated largely by junior miners and cross-listed resource stocks. For most diversified holders, these are satellite positions rather than core weights.
What to Watch
Three dynamics worth monitoring in this universe:
- Tech concentration risk — any repricing in large-cap semiconductors or cloud platforms propagates across more than half the tracked cap.
- Comm Services AI monetisation — Alphabet and Meta's ability to convert AI investment into revenue will set the tone for sector sentiment.
- Cross-listing noise — several tickers (Tesla's German listings, Obsidian's dual-listed shares) appear in multiple sectors' samples; Headmars deduplicates by underlying company, but investors should verify their own holdings aren't double-counted.
The universe is heavily weighted toward growth and innovation. That is a deliberate profile — but it means drawdowns in risk-off environments can be sharper than a traditionally balanced portfolio would suggest.
