Technology: The Anchor
With 469 companies and an aggregate market capitalisation of roughly $21.2 trillion, Technology is the undisputed centre of gravity in the Headmars tracked universe. The sample reads like a who's-who of the modern economy: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel together span consumer hardware, cloud infrastructure, AI silicon, enterprise SaaS, and legacy semiconductors. Coverage at this scale means the platform can surface cross-stock signals — for example, when a supply-chain move at INTC ripples into AMD or NVDA pricing.
For investors, the sheer density of this sector creates both opportunity and noise. Correlation within the cohort tends to spike during macro risk-off moves, which makes sector-level filtering (rather than name-by-name screening) a useful starting point.
Industrials: Broader Than You'd Think
At 318 names, Industrials is the second-largest sector by company count — and arguably the most globally diverse. The sample includes Honeywell and nVent alongside ZIM Integrated Shipping, Xiamen Solex (603992.SS), Archer Aviation, and a Taiwanese meter manufacturer (4588.TW). That breadth reflects the sector's structural role as a catch-all for manufacturing, logistics, aerospace, and electrification infrastructure.
The $3.36 trillion aggregate cap is modest relative to head count, signalling a long tail of small- and mid-cap names worth screening for cyclical exposure ahead of infrastructure-spending cycles.
Healthcare and Communication Services: High-Value Density
Healthcare covers 260 companies ($3.47T combined) with anchors like Johnson & Johnson, UnitedHealth, and AbbVie sitting alongside early-stage biotech (PenetriumBio, 187660.KQ) and consumer health platforms (GoodRx). The mix of defensive mega-caps and speculative small-caps makes this one of the more analytically interesting sectors for risk-adjusted return comparisons.
Communication Services is compact at just 59 names, yet the sample alone — Alphabet (twice, via GOOGL and GOOG), Meta, Netflix, Tencent (0700.HK), and Disney — illustrates how the sector punches far above its count. The $5.26 trillion aggregate cap reflects a handful of platform monopolies rather than broad coverage.
Financials and Basic Materials: Notable Aggregate Figures
Financials (88 companies) and Basic Materials (150 companies) both show large aggregate market-cap figures in the data. The Financials cohort includes Berkshire Hathaway, JPMorgan, Visa, Mastercard, and Bank of America — names whose individual scale moves sector totals significantly.
Basic Materials, by contrast, skews toward smaller international miners and fertiliser producers (lithium plays, gold juniors, Chinese fertiliser stocks). The divergence between company size and aggregate figures here is worth noting: cross-listings of the same underlying equity across multiple exchanges (as seen with Novo Resources on both TSX and ASX) can inflate raw counts and aggregates.
Consumer Cyclical and Energy: Familiar Names, Leaner Rosters
Consumer Cyclical (119 companies, ~$535B aggregate) features Amazon, Tesla, Home Depot, and Alibaba — again with Tesla appearing in both US and Frankfurt-listed forms. Energy (85 companies) spans US independents (Antero Resources), European majors (Shell), and Indian conglomerates (Reliance Industries).
What to Watch
Three structural themes emerge from this composition:
- AI hardware concentration — NVDA, AMD, and INTC sit within the same sector bucket; their relative performance is one of the most-watched sub-themes in the universe.
- Cross-listing noise — Several names (Tesla, Novo Resources, Galantas Gold) appear under multiple exchange tickers. Deduplication logic matters for accurate sector-weight calculations.
- Healthcare's barbell — Defensive pharma giants and micro-cap biotechs share a sector label but behave like different asset classes; sub-industry filters will be critical as the platform matures.
