The Universe at a Glance
As of July 7, 2026, the Headmars tracked universe spans 1,490 companies across eight sectors, with listings on at least seven exchanges: NYSE/NASDAQ, Hong Kong (HK), Shanghai (SS), Taiwan (TW), India's NSE (NS), Toronto (TO), London (L), and Frankfurt (F/DE). That geographic spread matters — this is not a US-centric slice of the market, but a genuinely cross-border view where a single sector's story can diverge sharply depending on which exchange you're reading.
Technology: King by Breadth
Technology leads all sectors by company count at 455 names — nearly a third of the entire tracked universe — and carries a combined tracked market cap of approximately $21.1 trillion. The anchor names are predictable in the best way: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel. The sector's density makes it both the richest screen for opportunity and the largest source of correlated risk. When semiconductor sentiment shifts, roughly a third of the tracked list moves with it.
Financials: Fewest Companies, Largest Aggregate Cap
With only 87 names, Financials is the second-smallest cohort by count — yet it registers the largest aggregate tracked market cap in the dataset. JPMorgan, Berkshire Hathaway, Visa, and Mastercard anchor a group whose per-company average towers over every other sector. The lesson for quantitative screens: equal-weight and market-cap-weight strategies will tell radically different stories here. A passive, cap-weighted approach to this universe tilts heavily toward a small number of financial mega-caps.
Communication Services: Maximum Influence, Minimum Breadth
At 56 companies, Communication Services is the smallest sector by count — yet it houses Alphabet (listed as both GOOGL and GOOG), Meta, Netflix, Disney, and Tencent. The thin roster means index-level moves are driven by a handful of names; a single earnings miss from one of these titans creates outsized ripple effects across the whole sector.
The Workhorse Middle: Industrials and Healthcare
Industrials (306 companies) and Healthcare (253 companies) form a diverse mid-tier that deserves more attention than it typically gets. Industrials ranges from Chinese high-tech manufacturing and global shipping (ZIM) to urban air mobility (Archer Aviation) and established conglomerates (Honeywell). Healthcare balances US pharma giants — J&J, UnitedHealth, AbbVie — against Korean biotech and Chinese pharmaceutical names, a reminder that drug development and managed care are no longer purely Western stories.
Basic Materials, at 135 companies, shows an unusually large aggregate market cap relative to its roster size, though the sample names skew toward smaller, globally dispersed miners and fertilizer producers. That concentration in a few large names warrants careful deduplication: cross-listed securities like Novo Resources (NVO.TO / NVO.AX) and Galantas Gold (GAL.V / GAL.L) appear under multiple tickers.
Three Things to Watch
- AI infrastructure concentration: NVIDIA, AMD, and Microsoft all sit in the largest sector by count. Any re-rating of AI capex expectations flows through Technology disproportionately.
- Cross-listing noise: Tesla appears under at least three tickers (TSLA, TL0.F, TL0.DE). Screens that skip deduplication will double- or triple-count exposure in Consumer Cyclical and elsewhere.
- EM divergence risk: Healthcare and Industrials carry meaningful Shanghai- and Taiwan-listed exposure. Regulatory shifts, currency moves, or geopolitical headlines can decouple these names from their Western sector peers in ways that aggregate sector metrics alone will not surface.
The breadth of the Headmars universe is its core strength for discovery. Managing the noise that comes with 1,490 names across seven exchanges is where the real analytical work begins.
