The shape of the universe
As of 4 August 2026, the Headmars universe spans 1,861 companies across eight sectors. The distribution is anything but even: the three largest sectors by headcount — Technology, Industrials and Healthcare — together account for more than 1,200 names, roughly two-thirds of everything we follow. The tail sectors, Communication Services (74) and Energy (106), are small by count but, as we'll see, punch far above their weight elsewhere.
Technology sets the pace
Technology is the clear leader by breadth, with 534 companies — about 29% of the universe. The sample reads like the sector's marquee list: Apple (AAPL), Microsoft (MSFT), NVIDIA (NVDA), AMD, Salesforce (CRM) and Intel (INTC). No other sector comes close on count. Industrials is second at 363 names — a genuinely global mix, from Honeywell (HON) and nVent (NVT) to Archer Aviation (ACHR), shipping's ZIM, and listings in Shanghai (603992.SS) and Taipei (4588.TW). Healthcare follows at 311, anchored by Johnson & Johnson (JNJ), UnitedHealth (UNH) and AbbVie (ABBV).
Where the names are vs. where the weight sits
Here the picture inverts. Rank the same sectors by reported aggregate market cap and Technology no longer leads. Financials, with just 111 names, carries the largest reported total ($159T), followed by Energy ($107T, 106 names) and Basic Materials ($46T, 224 names). Meanwhile Consumer Cyclical — home to Amazon (AMZN), Tesla (TSLA) and Home Depot (HD) across 138 names — shows the smallest reported aggregate cap ($556B). That is a striking mismatch between breadth and reported weight, and it's the most important thing to understand about this dataset.
Read the cap figures with care
The divergence is a signal to look closer, not to conclude that banks dwarf Big Tech. The sample names expose the likely culprit: cross-listings and duplicate tickers. Tesla appears twice in Consumer Cyclical (TL0.F and TL0.DE) on top of its primary line; Alphabet shows up as both GOOG and GOOGL; Basic Materials lists Novo Resources on two exchanges (NVO.TO, NVO.AX) and Galantas Gold on two more (GAL.V, GAL.L); Energy carries Obsidian twice (OBE, OBE.TO). These duplicates can inflate both counts and any naive cap aggregation, and they plausibly explain why the market-cap column and the headcount column tell different stories.
What an investor might watch
Three things stand out. First, concentration: nearly a third of tracked names are Technology, so the universe's mood will track that sector closely. Second, breadth in Materials and Industrials — both are heavy with international and smaller listings, offering diversification beyond the familiar US mega-caps. Third, data hygiene: before treating any sector's aggregate cap as gospel, de-duplicate the cross-listings. On Headmars, the count tells you where the opportunities are numerous; the cap column, once cleaned, tells you where the money truly concentrates — and right now those two views point in noticeably different directions.
