A Universe of 238 Names, Eight Sectors, Four Continents
The Headmars tracked universe currently spans 238 companies across eight sectors — from NASDAQ mega-caps to TSX Venture micro-miners. The distribution is anything but equal, and understanding where the weight sits is the first step toward managing concentration risk in any portfolio that overlaps this coverage.
Technology: The Undisputed Center of Gravity
At 74 companies and roughly $6.9 trillion in aggregate market cap, Technology is nearly half the total market weight in this universe. The roster runs the full stack: consumer hardware (AAPL), cloud infrastructure (MSFT), silicon design (NVDA, AMD), and enterprise software (CRM), with Intel representing the legacy foundry end of the curve. For any portfolio with meaningful overlap here, sector concentration is the first variable to stress-test — a broad de-rating in AI infrastructure spending would touch the majority of this universe simultaneously.
Communication Services: Lean Roster, Enormous Weight
Communication Services fields just 17 companies — the second-smallest sector by count — yet its $5.0 trillion aggregate cap makes it the second-heaviest sector overall. That compression reflects extreme top-of-funnel concentration: Alphabet (tracked as both GOOGL and GOOG), Meta, and Tencent could plausibly account for the vast majority of that figure. Netflix and Disney round out the media corner. Investors watching this sector should track regulatory risk (EU digital-markets enforcement, US antitrust posture) alongside AI monetization trajectories that span search, social, and streaming simultaneously.
Healthcare and Energy: The Mid-Tier Anchors
Healthcare (23 companies, ~$2.3 trillion) reads as a blue-chip-heavy bloc — Johnson & Johnson, UnitedHealth, and AbbVie anchor the US contingent — but Shanghai pharmaceutical and South Korean biotech names hint at emerging-market coverage at the early-stage end. The sector carries a bifurcated risk profile: large-cap defensives versus clinical-stage names where single trial outcomes drive outsized moves.
Energy (22 companies, ~$1.2 trillion) is genuinely global. XOM and Shell represent legacy integrated oil, Reliance Industries adds Indian downstream exposure, and Antero Resources brings US natural-gas leverage. The dual-listed Canadian operators (Obsidian Energy on both NYSE American and TSX) signal mid-cap, commodity-sensitive coverage extending well beyond the supermajors.
Industrials: Diversity Over Depth
Thirty industrials names spread $850 billion across a wide range of business models — container shipping (ZIM), diversified manufacturing (Honeywell), power management (nVent), and eVTOL aviation (Archer Aviation). Cross-listings of Chinese and Taiwanese names alongside US and European multinationals make this sector a useful proxy for global trade sentiment: freight rates and industrial order books often diverge precisely when supply-chain stress is building.
Consumer Sectors and Basic Materials: Thematic Long Tails
Consumer Cyclical (29 names) and Consumer Defensive (20 names) carry lower aggregate market-cap figures in the tracked data, suggesting coverage skews toward specific positions rather than comprehensive sector representation. Both sectors nonetheless include benchmark names — Amazon, Tesla, Home Depot; Walmart, Coca-Cola, Costco, Nestlé — making them useful for macro-cycle reads even at partial coverage.
Basic Materials (23 companies, ~$887 million aggregate) is the lightest sector by cap and the most geographically fragmented: Chinese fertilizer producers, dual-listed Canadian gold miners, and an Argentine lithium explorer occupy the same bucket. These names are high-beta and commodity-specific — valuable for critical-minerals and battery-supply-chain thematic tracking, but they require disciplined position sizing.
Three Dynamics Worth Watching
- AI capital expenditure cycling through Technology and Communication Services at the same time — a spending slowdown would compress both sectors simultaneously.
- Energy-transition linkages connecting Basic Materials (lithium, gold) to Industrials (electrification hardware) and Energy (legacy vs. renewables mix).
- Consumer bifurcation: defensives and value-oriented retailers may diverge sharply from discretionary names if rate expectations or consumer-credit conditions shift.
