The shape of the universe
As of 2026-08-20 the Headmars tracked universe spans 2,053 companies across eight sectors. By headcount, the distribution is decisively top-heavy toward Technology, which alone accounts for 573 names — more than one in four tickers we follow. Industrials (398) and Healthcare (340) round out the top three, with Basic Materials (267) close behind. The long tail is thinner: Financials (122), Energy (123), and Communication Services (82) each carry fewer than 150 names, and Consumer Cyclical sits at 148.
That count-based ranking is the reliable lens, and it says something simple: our universe is a technology-and-industrials universe first, with a deep bench of materials and healthcare small caps.
The names you'd expect — and the ones you wouldn't
The megacap anchors are all present. Technology leads with AAPL, MSFT, NVDA, AMD, CRM, and INTC. Communication Services is a concentrated who's-who — GOOGL, META, DIS, NFLX, and Tencent (0700.HK). Financials pairs BRK.B and JPM with the payment duopoly of V and MA, while Consumer Cyclical fronts AMZN, TSLA, and HD alongside Alibaba (9988.HK).
What's more telling is the breadth beneath the giants. Industrials reaches from Honeywell (HON) to Archer Aviation (ACHR) and Chinese and Taiwanese listings like Xiamen Solex and Arch Meter. Basic Materials is dominated by small-cap resource plays — Galantas Gold, Novo Resources, Argentina Lithium. This is a genuinely global, multi-exchange dataset, not an S&P mirror.
A caution on the market-cap totals
Here the data gets interesting. Ranked by reported totalMarketCapM, the order flips entirely: Financials ($159.4T), Energy ($106.5T), and Basic Materials ($47.1T) top the table, while Technology — the count leader — reports $22.6T and Consumer Cyclical trails at just $0.57T.
Treat those totals with skepticism. A $159T Financials sector or $106T Energy sector far exceeds any plausible real-world figure, and the sample names hint at why: the universe is riddled with cross-listings. Alphabet appears as both GOOG and GOOGL; Tesla shows up as TL0.F and TL0.DE; Novo Resources as NVO.TO and NVO.AX; Obsidian Energy as OBE and OBE.TO. Where the same issuer is counted on multiple exchanges, its cap is summed multiple times — inflating totals unevenly across sectors.
What an investor might watch
Three things. First, lean on company count, not the cap totals, when gauging where our coverage is genuinely deep — Technology and Industrials. Second, watch the concentration gap: Communication Services delivers enormous scale from just 82 names, so a single megacap's move swings that sector hard. Third, the cross-listing artifact is a data-hygiene flag worth resolving before any cap-weighted signal is trusted — de-duplicating issuers would materially reshuffle the reported rankings. Clean inputs first; conclusions second.
