Technology sets the pace
Across the eight sectors we track, 2,356 companies make up the universe as of 11 October 2026. Technology is the clear leader by headcount at 642 names — more than one in four of everything we follow — anchored by familiar large caps like Apple, Microsoft and NVIDIA, alongside semiconductor peers AMD and Intel and enterprise-software name Salesforce. The sheer breadth here reflects how much of the listed market now files under "tech," from chips to cloud.
Industrials follow at 449 companies and Healthcare at 388, together forming a solid middle tier. Industrials is the most geographically varied of the three: the sample runs from Honeywell and nVent to Archer Aviation, plus listings in Shanghai (Xiamen Solex) and Taiwan (Arch Meter). Healthcare spans mega-cap insurers and pharma — Johnson & Johnson, UnitedHealth, AbbVie — down to smaller names like GoodRx and listings in Shanghai and Korea.
The long tail is global and duplicated
Basic Materials (335) and Consumer Cyclical (171) show how international the coverage is. Materials leans toward miners and fertiliser producers across Hong Kong, Toronto, Australia and London; Consumer Cyclical pairs Amazon, Tesla and Home Depot with Alibaba in Hong Kong. Energy (141), Financials (140) and Communication Services (90) round out the set, the last concentrated in a handful of heavyweights — Alphabet, Meta, Netflix, Disney and Tencent.
One pattern jumps out of the sample names: the same company often appears under multiple tickers. Tesla shows up as TL0.F and TL0.DE, Novo Resources as NVO.TO and NVO.AX, Obsidian Energy as OBE and OBE.TO, Galantas Gold as GAL.V and GAL.L, and Alphabet as both GOOG and GOOGL. Cross-listings are a normal feature of a global universe, but they inflate raw counts and, more importantly, distort aggregate valuations.
A caution on the cap column
The market-cap totals in this snapshot should be read sceptically. Financials reports roughly $159T and Energy roughly $107T, each dwarfing Technology's $22.7T despite having a quarter of the company count — figures that are not credible for those sectors and point to double-counted cross-listings or unit/FX errors in the underlying data. When the smallest sectors by headcount carry the largest cap totals, the cap column is telling you about data hygiene, not about where value actually sits.
What an investor might watch
Two things. First, treat company count as the trustworthy signal in this snapshot: Technology and Industrials are where our coverage is deepest, and breadth there means more candidates to screen. Second, watch the de-duplication: until cross-listed tickers are consolidated, any sector-weight or concentration metric built on these cap totals will mislead. Cleaner inputs come first; sector calls come second.
