A Universe Dominated by Two Sectors
The 960 companies tracked across the platform are far from evenly distributed. Technology is the clear heavyweight: 289 names, a combined market cap of roughly $17.4 trillion, and household anchors including Apple, Microsoft, NVIDIA, and AMD. That single sector represents just over 54% of the entire tracked universe by capitalization — a concentration that mirrors broad index composition but also concentrates risk for any portfolio skewed toward it.
Communication Services punches even harder on a per-company basis. With only 34 names it contributes roughly $5.2 trillion — meaning each company averages more than $154 billion in cap. Alphabet (tracked under both GOOGL and GOOG), Meta, Netflix, Tencent, and Disney make this the most mega-cap-dense sector in the universe.
Together, these two sectors account for ~70% of total tracked market value despite holding fewer than a third of the companies.
The Mid-Tier: Healthcare, Industrials, and Energy
Healthcare is the second-largest sector by company count (188) and sits at roughly $3.3 trillion. The sample spans U.S. insurance giants (UnitedHealth), biopharma (AbbVie, Johnson & Johnson), a consumer health-tech name (GoodRx), and smaller international biotechs from Shanghai and Korea. That range — from defensive mega-caps to speculative small-caps — makes Healthcare one of the more volatile-in-aggregate sectors to model.
Industrials (161 companies, ~$3.0 trillion) shows clear international breadth: a Chinese high-tech manufacturer, an Israeli shipping line (ZIM), a U.S. conglomerate (Honeywell), an electric aviation startup (Archer Aviation), and a Taiwanese meter company. The sector is a useful bellwether for global trade and capital expenditure cycles.
Energy (51 companies, ~$1.8 trillion) skews toward large integrated majors — Exxon Mobil, Shell, Reliance Industries — alongside smaller natural gas and junior oil names. The cap-to-count ratio here is high relative to Industrials, suggesting the long tail is thin and the sector story is mostly told by the giants.
The Smaller Sectors: Worth Watching Disproportionately
Financials (54 companies, ~$625 billion) carries names like Berkshire Hathaway, JPMorgan, Visa, and Mastercard — a mix of conglomerate, bank, and payments-network exposure that behaves differently across rate environments.
Consumer Cyclical (81 companies, ~$465 billion) looks surprisingly low in aggregate cap given it includes Amazon and Tesla. This is partly a cross-listing artifact: Tesla appears under both TL0.F and TL0.DE (Frankfurt and Xetra), and Alibaba surfaces under its Hong Kong listing. Investors should be aware that the same underlying business can appear more than once across the tracked universe.
Basic Materials is the smallest sector by capitalization (~$112 billion, 42 companies), with representation concentrated in junior mining and fertilizer plays — Argentina lithium, Canadian gold explorers, a Chinese fertilizer producer. High speculative content; low correlation to core holdings.
What to Watch
- Concentration risk: a portfolio without intentional underweights in Technology and Communication Services will largely mirror the performance of a handful of mega-caps.
- Cross-listing duplicates: tickers like OBE/OBE.TO, NVO.TO/NVO.AX, and the Tesla Frankfurt listings represent the same equity. Aggregate position sizing should account for this.
- Healthcare's two-speed nature: pairing defensive pharma names against early-stage biotech in the same sector bucket masks very different risk profiles — worth segmenting at the sub-industry level.
- Energy as a macro signal: the presence of global majors (Shell in London, Reliance in Mumbai) alongside U.S. domestic producers means the sector aggregates serve as a rough proxy for global crude demand sentiment.
