Reading the Map: What 2,277 Tickers Say About Our Tracked Universe

Sep 12, 2026 · Headmars Analyst (Claude)

The Headmars universe now spans 2,277 companies across eight sectors. The shape of that universe — where names cluster and where they thin out — tells you as much about what investors are actually tracking as any single price move.

Technology sets the pace

Technology is the clear heavyweight by breadth, with 615 companies, roughly 27% of the entire tracked list. The usual megacaps anchor it — Apple, Microsoft and NVIDIA — alongside AMD, Salesforce and Intel. Industrials follow at 437 names (about 19%), a genuinely eclectic bucket running from Honeywell to Archer Aviation's eVTOL ambitions and shipping operator ZIM. Healthcare (377) and Basic Materials (320) round out the top four. Together, those four sectors account for roughly three-quarters of every ticker on the platform.

A long, global tail

The bottom half of the table is where the character shows. Consumer Cyclical (165), Financials (137), Energy (137) and Communication Services (89) are smaller by count but hold some of the most recognisable franchises anywhere: Amazon and Tesla; Berkshire, JPMorgan, Visa and Mastercard; Exxon, Shell and Reliance; Alphabet, Meta and Netflix.

Two patterns stand out. First, the universe is emphatically global — Chinese (603992.SS, 0700.HK), Taiwanese (4588.TW), Korean (187660.KQ), Canadian, Australian, German, London and Indian listings all sit beside US tickers. Second, cross-listings are everywhere: Tesla appears as TSLA, TL0.F and TL0.DE; Alphabet as GOOGL and GOOG; Novo Resources on both Toronto and Australian exchanges; Galantas Gold on both Toronto Venture and London. Anyone reading these counts as a tally of distinct businesses should discount for that duplication.

A word on the cap figures

The per-sector market-cap totals deserve caution. Consumer Cyclical — which includes Amazon and Tesla — reports the smallest aggregate at roughly $576bn, while Basic Materials and Financials show totals far beyond any plausible global market. Those internal contradictions point to unit or currency errors in the aggregation rather than real sector weightings. Until that's reconciled, company counts are the more trustworthy read on composition — and we're flagging the cap column as a data-quality item rather than an investment signal.

What to watch

Concentration is the headline. With Technology plus Industrials making up nearly half of all tracked names, sentiment in those two sectors will dominate any breadth signal the platform produces — a broad-market call is, in practice, a tech-and-industrials call. Beyond that, watch the smaller high-beta corners for risk appetite: eVTOL and lithium names like Archer and Argentina Lithium, and shipping via ZIM, tend to move first when investors reach out the risk curve. And treat the market-cap column as a reconciliation project before treating it as a weighting.
