The shape of what we track
As of 6 September 2026, the tracked universe spans 2,235 companies across eight sectors. Breadth — the count of distinct names — is the most honest lens here, and it tells a clear story about where investable attention concentrates.
Technology leads decisively with 603 companies, roughly 27% of the entire universe. That is more names than the next-largest sector by a wide margin, and the sample reads like a roll-call of the megacap complex: Apple, Microsoft, and NVIDIA sit alongside the semiconductor supporting cast of AMD and Intel, plus enterprise software in Salesforce.
Industrials is the surprise runner-up at 430 companies. This is where breadth diverges from the usual megacap narrative. Beyond Honeywell, the sample stretches into shipping (ZIM), electrical equipment (nVent), and — notably — early-stage aviation in Archer Aviation, along with listings from Chinese and Taiwanese exchanges. It is a reminder that industrials is a genuinely global, long-tailed sector.
Healthcare (370) and Basic Materials (313) round out the sectors carrying more than 300 names each. Healthcare anchors on Johnson & Johnson, UnitedHealth, and AbbVie, but the tail runs deep into small-cap and international biotech. Basic Materials skews toward miners and specialty producers.
Where breadth thins out
The count falls off sharply at the bottom. Communication Services (87) is the narrowest sector, yet it is arguably the most top-heavy by quality of name: Alphabet, Meta, Netflix, Disney, and Tencent do a lot of work in a small field. Energy (131), Financials (137), and Consumer Cyclical (164) are similarly concentrated — a handful of dominant franchises (Exxon, JPMorgan, Visa, Amazon, Tesla) plus a scattering of smaller peers.
A note on the numbers
The aggregate market-cap totals in the underlying data should be read with real caution, and I want to be transparent about that. The sample names themselves reveal the problem: duplicate cross-listings are everywhere — Alphabet appears as both GOOGL and GOOG, Tesla shows up as TL0.F and TL0.DE, and names like Novo Resources (NVO.TO / NVO.AX), Galantas Gold (GAL.V / GAL.L), and Obsidian Energy (OBE / OBE.TO) are each counted more than once. Multiple listings and mixed currency denominations inflate any naive cap total, which is why the reported aggregates rank sectors in an order that breadth does not support. For now, treat counts as trustworthy and headline caps as noisy.
What an investor might watch
Three things stand out. First, the Technology-plus-Industrials axis now accounts for nearly half the tracked names — a barbell of megacap software and a sprawling, globalised industrial base. Second, watch the industrial long tail, where speculative names like Archer Aviation live beside established compounders; breadth there is a signal of thematic interest, not necessarily of quality. Third, the cross-listing clutter is a data-hygiene item worth resolving before any cap-weighted analysis — deduplicating tickers is the prerequisite for trusting sector weights at all.
