Breadth: a technology-led roster
By sheer count, the tracked universe skews heavily toward technology. Of roughly 2,478 companies across eight sectors, Technology leads with 656 names (~26%), anchored by familiar megacaps — Apple, Microsoft, NVIDIA — alongside the semiconductor cohort of AMD and Intel and software franchises like Salesforce.
Behind it sits a cyclical, industrial middle. Industrials (475), Healthcare (409), and Basic Materials (358) together account for more than half the roster. Industrials spans the recognisable (Honeywell) and the speculative (Archer Aviation), while Healthcare pairs defensive giants — Johnson & Johnson, UnitedHealth, AbbVie — with small international listings. The long tail is thinner: Consumer Cyclical (186), Financials and Energy (149 each), and Communication Services (96).
Weight: a very different league table
Rank the same sectors by reported market cap and the picture inverts. Financials tops the table at roughly $159.5T, followed by Energy (~$106.6T) and Basic Materials (~$47.2T). Technology — the largest by headcount — comes in fourth by this measure at $23.1T, ahead of Communication Services ($5.3T) and Healthcare (~$3.7T).
That ordering should raise an eyebrow, and it's worth saying so plainly. Financials showing seven times Technology's capitalisation, or Consumer Cyclical (home to Amazon and Tesla) registering just ~$0.58T, does not reflect how global equity weight is usually distributed. The figures are presented here as the data reports them, but they look distorted rather than descriptive.
The likely culprit: cross-listings and data hygiene
The sample names hint at why. The universe is full of the same company listed on multiple venues: Novo Resources appears as both NVO.TO and NVO.AX, Galantas Gold as GAL.V and GAL.L, Obsidian Energy as OBE and OBE.TO, Tesla as TL0.F and TL0.DE, and Alphabet as both GOOG and GOOGL. Where those duplicates carry a market-cap value each, the sector total double- (or triple-) counts the same equity — and currency handling across exchanges compounds the error.
That makes the headcount figures the more trustworthy lens for now. The cap totals are useful directionally, but any serious sector-weight comparison should wait until duplicate listings are de-duplicated to a single primary ticker.
What an investor might watch
- Concentration risk in Technology. With a quarter of the roster in one sector led by a handful of megacaps, breadth here is more apparent than real — moves in Apple, Microsoft and NVIDIA will dominate any tech-weighted view.
- The cyclical core. Industrials, Healthcare and Basic Materials give the universe genuine diversification across the economic cycle, from aviation to pharma to fertiliser and mining.
- Data quality as a first-class metric. Before trusting any sector-allocation conclusion, confirm the cap figures survive de-duplication. The cleanest investment signal this month may simply be that the pipeline needs a single-primary-listing rule.
The tracked universe is wide and genuinely global. The job now is making its numbers as trustworthy as its coverage.
