The shape of the universe
As of 14 November 2026, the Headmars universe spans 2,513 tracked companies across eight sectors, and the distribution is lopsided. Technology alone accounts for 662 names — roughly a quarter of everything we follow — ahead of Industrials (481), Healthcare (416) and Basic Materials (363). The tail runs through Consumer Cyclical (191), Financials and Energy (151 each) and Communication Services (98). Notably, Communication Services is the smallest sector by count yet carries some of the largest businesses in the world: Alphabet, Meta, Netflix, Disney and Tencent.
Technology leads, but depth lives below the mega-caps
Technology's dominance is unsurprising given its sample — Apple, Microsoft and NVIDIA sit alongside AMD, Salesforce and Intel. Three of those six (NVIDIA, AMD, Intel) are semiconductor names, a reminder that the AI-and-silicon trade is structurally over-represented in what investors choose to track.
The more interesting story is what sits beneath the giants. Industrials, our second-largest sector, mixes Honeywell and nVent with Israeli container shipper ZIM, eVTOL hopeful Archer Aviation, and small Asian manufacturers like Xiamen Solex and Taiwan's Arch Meter. Healthcare pairs Johnson & Johnson, UnitedHealth and AbbVie with GoodRx and tiny listings out of Shanghai and Korea. This is not a US-blue-chip index; it is a sprawling, global catalogue.
Dual listings inflate the count
Basic Materials (363 names) rewards a closer look. The sample is dominated by small miners and chemical producers — lithium, gold, fertilizer — and by the same company appearing more than once: Novo Resources as both NVO.TO and NVO.AX, Galantas Gold as GAL.V and GAL.L. The pattern repeats across the universe — Tesla as TSLA, TL0.F and TL0.DE; Alphabet as GOOGL and GOOG; Obsidian Energy as OBE and OBE.TO. Cross-listings meaningfully pad the raw counts, so read each sector's size as "tickers tracked," not distinct businesses.
Treat the cap totals with caution
The aggregate market-cap figures in this snapshot do not hang together. Consumer Cyclical holds Amazon, Tesla, Home Depot and Alibaba yet reports the smallest total of any sector, while Financials and Energy report figures larger than the entire world's equity value. Something is clearly wrong in the cap feed — most likely a currency or units mix-up across exchanges — and no allocation decision should lean on these totals until they are reconciled.
What to watch
Three threads stand out. First, concentration risk in Technology: a quarter of the universe, heavily levered to semiconductors. Second, the Industrials wildcards — shipping cycles (ZIM) and next-generation aviation (Archer) — that behave nothing like Honeywell. Third, the Basic Materials small-cap tail, where lithium and gold names offer commodity-cycle leverage but demand scrutiny on liquidity and duplicate listings. The headline is breadth; the discipline is knowing which of these names are real signal.
