Technology: The Undisputed Centre of Gravity
With 326 names and roughly $17.9 trillion in combined market capitalisation, Technology accounts for nearly half the total universe by value. Apple, Microsoft, NVIDIA, and AMD anchor the large-cap end, while the sector's breadth spans enterprise software (Salesforce) and legacy hardware (Intel). The concentration is striking: one sector holds more market cap than the other seven combined.
For watchers, the central question is AI-driven capital allocation. NVIDIA's position as a GPU-demand bellwether means any signal from its order book ripples across the entire sector — and into the Communication Services and Financials names that run AI workloads at scale.
Financials: Fewer Names, Enormous Weight
Sixty-one companies generate $6.2 trillion in market cap — an average of over $100 billion per name. JPMorgan, Berkshire Hathaway, Visa, and Mastercard dominate. The low company count relative to value flags how top-heavy this sector is: a handful of mega-banks and payment rails carry nearly all the weight. Rate sensitivity and credit-cycle dynamics make Financials the sector most exposed to macro inflection points.
Communication Services: The Quiet Heavyweight
Forty names, $5.2 trillion. The per-company average — roughly $131 billion — is the highest of any sector in the universe, reflecting a cohort built almost entirely around mega-cap platforms: Alphabet (tracked as both GOOGL and GOOG), Meta, Tencent, Netflix, and Disney. Regulatory risk (EU Digital Markets Act, US antitrust proceedings) and advertising-cycle exposure are the chief watchpoints here.
Healthcare and Industrials: Broad but Cap-Constrained
Healthcare (195 companies, $3.3T) and Industrials (189 companies, $3.0T) are the deepest sectors by name count after Technology. Healthcare ranges from US managed-care giants (UnitedHealth, AbbVie, Johnson & Johnson) to Korean biotech and Chinese pharma, flagging meaningful cross-border coverage. Industrials shows similar global breadth — Honeywell alongside ZIM Integrated Shipping and Chinese industrial manufacturers.
Both carry lower per-company averages, indicating a mix of large anchors and mid/small-cap names. Patent cliffs in biopharma and freight-rate volatility in shipping are near-term focal points.
Consumer Cyclical: Concentrated at the Top
Eighty-four companies, $519 billion in combined cap. The sector sample is anchored by Amazon and Tesla — and Tesla itself appears under three tickers (TSLA, TL0.F on Frankfurt, TL0.DE on XETRA), illustrating the cross-listing duplicates that portfolio trackers must reconcile to avoid inflating exposure metrics.
Energy and Basic Materials: The Tail
Energy (54 names, $1.8T) features global majors — ExxonMobil, Shell, Reliance Industries — alongside smaller Canadian and US producers. Basic Materials is the smallest sector by market cap ($114B across 56 names), populated largely by junior miners and explorers listed on TSX Venture, ASX, and HKEX. The average company size here is roughly $2 billion, an order of magnitude below the universe mean.
Three Themes to Watch
- AI infrastructure spend — Technology and Communication Services capex cycles are tightly coupled; GPU allocation and cloud-revenue trajectory are the leading signals across both sectors.
- Rate sensitivity — Financials' mega-cap concentration means interest-rate direction has outsized impact on overall portfolio value, even though the sector holds only 61 names.
- Cross-listing noise — Multiple tickers for the same underlying (Tesla on three exchanges, Alphabet as GOOGL/GOOG, Obsidian Energy on TSX and OTC) require deduplication logic to prevent inflated exposure readings and double-counted sector weights.
