The Universe at a Glance
As of 30 June 2026, Headmars tracks 1,363 companies across eight sectors, spanning exchanges from NASDAQ and NYSE to the Hong Kong Stock Exchange, Frankfurt, Taiwan, and beyond. That global reach is intentional — the platform is built for investors who don't stop at their home bourse. What the composition of that universe tells us is worth unpacking.
Technology: The Undisputed Anchor
With 426 companies and an aggregate market cap of roughly $19 trillion, Technology is the heaviest sector by both breadth and weight. The names anchoring it need little introduction — Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel — but the sheer count (31% of all tracked names) underscores how much of modern investable equity is effectively a bet on software, semiconductors, and cloud infrastructure.
For anyone building a diversified portfolio on the platform, Technology's gravitational pull is the first risk to manage. A passive equal-weight approach still tilts heavily tech simply due to the number of names available.
A Basic Materials Outlier
The sector that demands the most scrutiny is Basic Materials: 105 companies, yet an aggregated figure of approximately $44.2 trillion — larger than Technology and Financials combined. The sample names reveal why caution is warranted: several securities appear as cross-listed twins (NVO.TO / NVO.AX, GAL.V / GAL.L), and lithium and gold junior miners sit alongside Chinese fertiliser producers. Aggregating market cap across duplicate listings of the same underlying company can inflate sector totals significantly.
This is not a call to distrust the data — it is a call to interrogate it. Investors screening by sector market cap should verify that cross-listed duplicates are not double-counted in their exposure calculations.
Financials and Communication Services: Concentrated Heavyweights
Financials (78 companies, ~$17.4T) punches well above its count. Berkshire Hathaway, JPMorgan Chase, Visa, and Mastercard alone represent an enormous share of that total. The sector's relatively small company count means any screen here will surface mega-caps quickly — useful for blue-chip tilts, less so for discovery.
Communication Services (52 companies, ~$5.2T) is similarly top-heavy: Alphabet appears twice (GOOGL and GOOG share classes), Meta, Netflix, Disney, and Tencent account for the bulk of market cap. The sector is effectively a proxy for advertising and streaming duopolies, with genuine media diversity thin on the ground.
Healthcare and Industrials: Depth Without Dominance
Healthcare (229 companies, ~$3.3T) and Industrials (289 companies, ~$3.3T) are nearly identical in aggregate market cap despite Industrials carrying 60 more names. Healthcare's roster spans US pharma giants like Johnson & Johnson, AbbVie, and UnitedHealth alongside Korean biotech (PenetriumBio) and Chinese pharmaceutical names — a genuine cross-border mix.
Industrials shows the platform's global ambition most clearly: a Chinese high-tech manufacturer, a Taiwanese meter company, an Israeli shipping line, and Archer Aviation (eVTOL) share sector space with Honeywell. The dispersion of business models here is wide.
Smaller Sectors, Specific Signals
Consumer Cyclical (111 companies, ~$534B) is the smallest by market cap despite including Amazon, Tesla, Home Depot, and Alibaba. The Tesla duplicates (TL0.F / TL0.DE) mirror the cross-listing issue seen in Basic Materials.
Energy (73 companies, ~$1.8T) covers the spectrum from ExxonMobil and Shell to Antero Resources and Obsidian Energy — majors alongside smaller E&P names that carry meaningfully different risk profiles.
What to Watch
Three things stand out for investors using this universe:
- Deduplication matters. Cross-listed securities inflate sector totals and skew screens. Any market-cap-weighted analysis should normalise for them.
- Technology concentration is structural. With 31% of tracked names and ~$19T in cap, tech exposure is the default, not the exception.
- Healthcare depth offers diversification value. At 229 names spanning geographies and sub-industries, it is the sector most likely to surface non-correlated opportunities relative to the tech core.
