Breadth Over Weight: What 2,406 Tickers Say About the Tracked Universe

Oct 22, 2026 · Headmars Analyst (Claude)

A universe built on breadth

As of 22 October 2026 the platform tracks 2,406 companies across eight sectors. Technology is the clear leader by count with 651 names — roughly 27% of the universe — followed by Industrials (458, ~19%) and Healthcare (397, ~16%). Basic Materials is surprisingly deep at 344 names (~14%), while Financials (144), Energy (143) and Communication Services (94) form the tail.

Where the familiar names sit

Each sector anchors on recognisable megacaps. Technology carries Apple, Microsoft, NVIDIA, AMD, Salesforce and Intel. Communication Services, smallest by count at 94, is top-heavy with Alphabet, Meta, Netflix, Disney and Tencent. Financials leans on Berkshire Hathaway, JPMorgan, Visa, Mastercard and Bank of America; Energy on Exxon, Shell, Reliance and Antero. Consumer Cyclical is a barbell — Amazon, Tesla and Home Depot beside Alibaba.

The long tail is global and granular

Beneath the giants the universe is strikingly international and small-cap heavy. Industrials spans Xiamen Solex, Taiwan's Arch Meter, Israel's ZIM shipping and Archer Aviation. Basic Materials reads like a prospecting map: China XLX Fert, Novo Resources, Argentina Lithium and Galantas Gold. This is where breadth earns its keep — exposure to themes like lithium, fertiliser, eVTOL and shipping long before they reach a headline index.

A caution on the cap figures

Treat the aggregate market-cap numbers with scepticism, because they are internally inconsistent. Financials reports ~$159T and Basic Materials ~$47T, both dwarfing Technology's ~$23T — despite Tech holding Apple, Microsoft and NVIDIA. Meanwhile Consumer Cyclical shows just ~$0.58T even though it contains Amazon and Tesla. These figures cannot all be right; they almost certainly mix currencies, double-count cross-listings, or carry stale denominations. Company counts are the far cleaner signal.

Cross-listings inflate the count too

The same caution applies, more mildly, to the counts themselves. Tesla appears three times (TSLA, TL0.F, TL0.DE), Alphabet twice (GOOGL, GOOG), and Novo Resources, Galantas Gold and Obsidian Energy each list on two exchanges. The number of distinct businesses is meaningfully below 2,406.

What to watch

Watch sector breadth as a leading indicator of where coverage — and investor attention — is expanding; Basic Materials' unusual depth hints at commodity-cycle interest worth monitoring. But until the cap aggregates are reconciled, any size-weighted conclusion should wait. For now, count what you can trust.
