Technology: Wide, Deep, and AI-Adjacent
With 479 tracked companies and a combined market capitalisation of roughly $21.2 trillion, Technology is the broadest sector in this universe by a substantial margin — more than 40% more names than the next-largest sector, Industrials. Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel represent the full stack of the modern tech economy: consumer devices, cloud platforms, AI silicon, and enterprise SaaS. For investors watching this cohort, the AI-infrastructure names (NVDA, AMD, MSFT) carry the most forward-looking weight, while legacy chipmakers like Intel occupy a more contested role in any conviction-driven allocation.
Financials: The Market Cap Anchor
Despite fielding only 89 companies — near the bottom by headcount — Financials registers the highest aggregate market cap in the tracked universe. Berkshire Hathaway, JPMorgan Chase, Visa, Mastercard, and Bank of America represent durable economic infrastructure. Payments networks and diversified banking giants tend to be core positions rather than thematic bets, which partly explains why this sector punches far above its weight in dollar terms relative to its company count.
Basic Materials: A Globally Dispersed Heavyweight
At 158 names, Basic Materials sits mid-table by count yet records the second-highest aggregate valuation. The sample spans Shanghai fertiliser producers, a Canadian lithium play, an Australian gold miner, and Hong Kong-listed commodity businesses — a genuinely cross-continental mix. The presence of Argentina Lithium and Galantas Gold signals an ongoing energy-transition and precious-metals theme that is worth monitoring as commodity cycles mature.
Industrials and Healthcare: Scale Without the Spotlight
Industrials (325 companies, ~$5.3 trillion) and Healthcare (268 companies, ~$3.5 trillion) are the second and third most populous sectors, respectively, yet neither approaches the top in per-name market cap. Industrials is eclectic: Honeywell and electric-aviation newcomer Archer Aviation sit alongside Chinese high-tech manufacturers and a Taiwanese meter company — a reminder that the tracked universe is not a US-centric list. Healthcare pairs blue-chip anchors (JNJ, UNH, AbbVie) with early-stage biotech names from Korea and China, layering speculative upside onto a defensive base.
Communication Services and Energy: Lean Rosters, Outsized Names
Communication Services fields just 61 companies — the smallest count of any sector — yet its roster includes Alphabet (in two share classes), Meta, Netflix, Walt Disney, and Tencent. For thematic exposure to digital advertising, streaming, and social media, this compact group does significant work. Energy (85 companies, ~$1.8 trillion) is anchored by ExxonMobil, Shell, and Reliance Industries, with smaller pure-plays like Antero Resources and Obsidian Energy adding cyclical leverage.
Consumer Cyclical: The Outlier to Investigate
Consumer Cyclical is the statistical curiosity of this snapshot. Its 125 companies include Amazon and Tesla — two of the most valuable companies in the world — yet the sector's aggregate market cap of roughly $540 billion is by far the lowest of any cohort, well below even Energy. The presence of multiple Tesla cross-listings (NYSE, Frankfurt, Xetra) suggests that deduplication and cross-listing treatment may be driving the figure. Treat sector-level totals here as a prompt for position-level investigation rather than a reliable allocation weight.
What to Watch
The global character of this universe — listings across NYSE, Nasdaq, Shanghai, Hong Kong, Taiwan, Toronto, London, and Frankfurt — means FX exposure is a quiet but persistent risk factor that sector weights alone will not capture. Technology's breadth and Financials' market cap concentration set up the two most likely drivers of aggregate volatility in any given reporting period. As AI-infrastructure spending continues to evolve, the spread between Technology's raw company count and its per-name average valuation will be the ratio worth revisiting each quarter.
