By the Numbers: 1,305 Companies Across Eight Sectors
As of 28 June 2026, the Headmars discovery engine is actively tracking 1,305 companies spanning eight sectors, with representation across US, Hong Kong, Taiwanese, German, Indian, Australian, and Canadian listings. That cross-exchange breadth is intentional — the platform's discovery mandate is global, not just S&P-centric.
Technology: The Undisputed Center of Gravity
With 403 companies and roughly $18.9 trillion in combined market cap, Technology is the commanding sector in the universe. The sample roster tells the story: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel represent the spectrum from mega-cap consumer hardware to enterprise cloud to the AI silicon race. NVIDIA and AMD in particular sit at the epicenter of the 2020s infrastructure buildout; their weight within this sector alone can move aggregate Technology figures meaningfully.
Investors watching this sector should note how tightly the aggregate cap is clustered around a handful of names. 403 tracked companies sounds diversified — but the distance in market cap between the top five and the next hundred is enormous.
Financials and Communication Services: Fewer Names, Outsized Weight
Financials covers only 74 companies yet carries approximately $16.1 trillion in aggregate cap — the second-largest figure in the universe after Technology. Berkshire Hathaway, JPMorgan, Visa, Mastercard, and Bank of America anchor this group. The per-company average here is striking, reflecting how financial giants compound value quietly compared to the headline-grabbing tech cohort.
Communication Services is the leanest sector by company count (49) but punches well above its weight at $5.2 trillion. Alphabet (tracked under both GOOGL and GOOG tickers), Meta, Netflix, Disney, and Tencent make this a who's-who of global media and digital advertising — a sector that increasingly overlaps with AI infrastructure as these platforms deploy large-scale model workloads.
The Deep Bench: Industrials and Healthcare
Industrials (280 companies, ~$3.3T) is the second-broadest sector and arguably the most globally diverse, mixing Chinese manufacturing names like XIAMEN SOLEX, global shipping via ZIM, legacy conglomerates like Honeywell, and early-stage plays like Archer Aviation. The eVTOL name is a signal that the platform's discovery process isn't just indexing incumbents.
Healthcare (225 companies, ~$3.3T) shows a similar mix: blue-chip anchors in JNJ, UNH, and ABBV alongside Korean biotech (PenetriumBio) and Chinese pharma (Shanghai Xiao Fang). Investors should watch for regulatory catalysts across these geographies — a NMPA approval in China or FDA action in the US can move small-cap healthcare names sharply.
Smaller Sectors Worth Monitoring
Energy (71 companies, ~$1.8T) covers the spectrum from supermajors (ExxonMobil, Shell, Reliance) to small Canadian and US E&P names. Consumer Cyclical (108 companies, ~$534B aggregate) is headlined by Amazon and Tesla but also includes Alibaba and Home Depot — a category sensitive to macro rate cycles and consumer sentiment shifts.
Basic Materials (95 companies) is dominated by junior miners, lithium plays, and gold names. The aggregate market cap figure for this sector appears anomalous relative to its sample composition and may reflect data normalization artifacts across exchange currencies; it is flagged for review rather than used as a benchmark.
What to Watch
Three signals stand out for the near term: (1) whether AI capex names in Technology sustain momentum as hyperscaler earnings land; (2) Financials volatility tied to rate-cut timing — Visa and Mastercard move differently than regional banks; and (3) Healthcare catalysts from cross-listed biotech names where geopolitical news can trigger outsized moves. The platform's global listing coverage means these signals surface earlier than a US-only screen would allow.
