As of 3 September 2026, the Headmars platform tracks roughly 2,200 companies across eight sectors. Looking at how those names distribute — and, just as importantly, where the numbers don't quite add up — offers a useful map of where breadth and attention concentrate.
Technology and Industrials lead by breadth
Technology is the deepest sector we track, with 596 companies — think Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel anchoring a long tail of smaller names. Industrials follows with 424 companies, a notably international group that ranges from Honeywell and nVent to Chinese and Taiwanese manufacturers (Xiamen Solex, Arch Meter) and newer entrants like Archer Aviation in electric aircraft. Healthcare (368) and Basic Materials (304) round out the top four by count.
The pattern here is clear: breadth clusters in Technology and Industrials. For an investor, that depth cuts both ways — more choice, but also more names competing for a finite slice of attention and capital.
The long tail: cyclicals, financials, energy
The remaining sectors are narrower. Consumer Cyclical (162) carries household bellwethers — Amazon, Tesla, Home Depot, Alibaba — while Financials (133) leans on Berkshire Hathaway, JPMorgan, Visa, and Mastercard. Energy (128) spans the supermajors (Exxon, Shell, Reliance) alongside smaller producers like Obsidian and Antero. Communication Services is the slimmest at 87, yet it holds some of the largest franchises anywhere: Alphabet, Meta, Netflix, Disney, and Tencent.
That last point is worth dwelling on. A low company count does not imply a small sector — Communication Services proves that a handful of mega-caps can carry enormous weight.
A data caveat worth flagging
The sector-level market-cap totals in this snapshot deserve scepticism, and I'd rather say so than paper over it. Consumer Cyclical — home to Amazon and Tesla — reports the smallest aggregate market cap of any sector, while Basic Materials and Financials report totals that dwarf Technology. Those relationships run counter to how these names trade in reality. The likely culprits are duplicate cross-listings (note the repeated Tesla, Novo Resources, and Obsidian tickers across exchanges) and inconsistent units or stale figures feeding the aggregation.
The takeaway: trust the company counts, treat the market-cap totals as provisional. They're a reminder that any screen is only as good as its underlying data hygiene.
What to watch
Three things stand out. First, the cross-listing noise — deduplicating tickers like TSLA/TL0.F/TL0.DE would sharpen every downstream metric. Second, the international spread in Industrials and Basic Materials suggests our universe is genuinely global, not US-only, which matters for currency and liquidity assumptions. Third, the concentration of value in a few Communication Services and Technology names means index-level moves will keep hinging on a short list of mega-caps.
Composition is the quiet foundation of every portfolio decision. Getting the map right — and admitting where it's smudged — comes before drawing any route.
