The Big Three by Company Count
Technology leads the universe by a significant margin: 445 companies, nearly 31 % of the total tracked set, and a combined market cap approaching $19 trillion. Familiar mega-caps — Apple, Microsoft, NVIDIA, AMD, Salesforce, Intel — anchor the cohort, but the sector's depth extends well beyond household names. When Technology moves, it moves the portfolio.
Industrials is the second-largest segment at 302 companies. The sample names alone reveal the sector's geographic breadth: Chinese manufacturer Xiamen Solex, Taiwanese Arch Meter, Israeli-listed global shipper ZIM, and US stalwarts Honeywell and nVent Electric. Industrial signals here reflect macro forces — electrification capex, shipping rates, aerospace supply chains — rather than any single theme.
Healthcare rounds out the top three with 247 companies. The cohort blends US defensive mega-caps (Johnson & Johnson, UnitedHealth, AbbVie), patient-economy disruptors (GoodRx), Chinese pharma (Shanghai Xiao Fang), and speculative emerging biotech (PenetriumBio, Korea). That wide dispersion of risk profiles means Healthcare returns rarely move in lockstep — treat large-cap pharma and small-cap biotech as separate buckets.
Mid-Tier Sectors Worth Watching
Basic Materials (132 companies) skews heavily toward small- and micro-cap miners and commodity producers: Argentina Lithium, Galantas Gold (cross-listed in Canada and London), Novo Resources, and Chinese fertilizer names. Liquidity and volatility can be extreme here; the cohort tends to front-run commodity cycle turns before broader market data catches up.
Consumer Cyclical packs concentrated star power into 115 names. Amazon, Tesla, Home Depot, and Alibaba account for an outsized share of sector weight. The multiple Tesla listings (US, Frankfurt, XETRA) are a reminder that de-duplicating cross-listed names before weighting is essential across the full universe.
Communication Services (56 companies) reads like a concentration study: Alphabet (both share classes), Meta, Netflix, Disney, and Tencent. Small count, enormous implied weight — a handful of earnings reports can move the entire sector reading.
Financials and Energy
Financials (86 names) includes the dominant global franchises — Berkshire Hathaway, JPMorgan, Visa, Mastercard, Bank of America — alongside regional players like Austria's Oberbank. The sector is lean by count but carries systemic importance; any macro rate regime shift ripples broadly.
Energy (78 companies) is the smallest sector and the most geographically dispersed: US E&P names (Exxon, Antero Resources), European majors (Shell), Indian conglomerates (Reliance Industries), and smaller Canadian oil names. That spread means energy signals can diverge sharply based on regional pricing and regulatory dynamics.
Structural Observations
A few things investors should keep in mind when reading cross-sector signals from this universe:
- Technology concentration: at 31 % of all companies and the largest reported market cap, Tech results can mask performance divergence in smaller sectors.
- Cross-listing noise: several underlyings appear under multiple tickers across exchanges. Weighting models need deduplication logic before aggregating sector-level signals.
- Basic Materials as a sentiment barometer: the lithium and gold names in this cohort have historically led — and occasionally mislead — broader commodity cycle calls.
- Communication Services efficiency: six companies cover most of the sector's systemic weight; monitoring this cohort requires fewer names but higher per-name scrutiny.
