As of 16 October 2026, the Headmars tracked universe spans eight sectors and 2,372 companies. How you rank those sectors depends entirely on which column you read — and the two columns tell very different stories.
Technology sets the pace
By company count, Technology is the clear leader with 646 names, roughly 27% of the entire universe. Industrials follow at 452 (about 19%) and Healthcare at 390 (about 16%). Together, those three sectors account for nearly 63% of everything tracked. The remaining five — Basic Materials (337), Consumer Cyclical (171), Financials (142), Energy (141) and Communication Services (93) — split the rest.
The Technology bench is recognisable: Apple, Microsoft and NVIDIA sit alongside AMD, Salesforce and Intel. These are the mega-caps that dominate most real-world indices, which makes what the market-cap column claims all the more striking.
The cap column disagrees — and looks wrong
Ranked by reported total market cap, the order inverts. Financials lead at roughly $159.5T, Energy at $106.6T and Basic Materials at $47.2T, while Technology lands fourth at just $22.7T. Consumer Cyclical — the sector that houses Amazon and Tesla — comes last at a barely-credible $0.58T.
That ordering does not survive a sanity check. A universe where Technology carries the largest roster of the world's biggest companies yet reports a fraction of the Financials or Energy totals is not describing the market; it is describing a data problem. The sample names hint at why: the universe is full of duplicate cross-listings — Tesla appears as TL0.F and TL0.DE, Alphabet as both GOOGL and GOOG, Novo Resources as NVO.TO and NVO.AX, Galantas Gold as GAL.V and GAL.L, Obsidian Energy as OBE and OBE.TO. Double-counting and mixed-currency or stale cap values will inflate some sectors and gut others.
The practical takeaway: treat company count as the reliable signal here and the aggregate market-cap figures as suspect.
Names worth watching
The sample names also show how global and uneven the coverage is. Beyond the US mega-caps, the universe reaches into Xiamen Solex and Shanghai pharma listings, Hong Kong's Tencent and Alibaba, India's Reliance, and a long tail of small-cap miners and speculative aviation plays like Archer Aviation. Communication Services is small by count (93) but concentrated in heavyweights — Alphabet, Meta, Netflix, Disney and Tencent.
What an investor might watch
Three things stand out. First, concentration risk: a portfolio drawn naively from this universe skews heavily toward Technology, Industrials and Healthcare. Second, the duplicate listings — anyone screening or weighting by the raw universe should de-duplicate cross-listed tickers before drawing conclusions. Third, and most important for a platform like this, the market-cap discrepancy is a reminder that aggregate figures are only as good as their inputs. The count tells a clean story; the cap column tells us where the data pipeline still needs cleaning.
