The shape of the tracked universe
Headmars currently follows 2,464 instruments across eight sectors, and the distribution is anything but even. By company count the universe leans technical and industrial: Technology alone accounts for 655 names (about 27%), followed by Industrials at 472 (19%) and Healthcare at 408 (17%). Add Basic Materials' 354 listings (14%) and just four sectors cover roughly three-quarters of everything we watch.
The thin end is equally telling. Communication Services holds only 96 names (4%), Financials and Energy sit at 147 and 148 respectively (6% each), and Consumer Cyclical rounds things out at 184 (7%).
Where the familiar names live
Technology's roster reads like the market's center of gravity — Apple, Microsoft, NVIDIA, AMD, Salesforce, Intel. Communication Services, small by count, is dense with mega-caps: Alphabet, Meta, Netflix, Disney, Tencent. Consumer Cyclical carries Amazon, Tesla and Home Depot; Financials anchors on Berkshire Hathaway, JPMorgan, Visa and Mastercard. Headline weight and headcount plainly don't move together — a handful of giants can dominate a numerically small sector.
A genuinely global, and duplicated, list
The samples show how wide the net is cast: Shanghai (603992.SS), Hong Kong (1866.HK, 9988.HK, 0700.HK), Taipei (4588.TW), Seoul (187660.KQ), Mumbai (RELIANCE.NS) and London (SHEL.L) all appear beside US tickers. That breadth is a feature, but it comes with a wrinkle — the universe holds the same company under several listings. Tesla appears as TSLA, TL0.F and TL0.DE; Alphabet as GOOGL and GOOG; Novo Resources as NVO.TO and NVO.AX; Galantas Gold as GAL.V and GAL.L. Raw counts therefore overstate the number of distinct businesses, most visibly in Basic Materials and Consumer Cyclical.
A word on the cap figures
The aggregate market-cap totals deserve scepticism, not headlines. They rank Financials and Energy far above Technology, and place Consumer Cyclical — home to Amazon and Tesla — dead last. That ordering contradicts the names sitting inside each bucket and almost certainly reflects stale quotes, currency-unit mismatches, or duplicate listings inflating some totals. For now, treat company counts as the reliable signal and the cap column as a data-quality flag to be fixed, not a conclusion to publish.
What to watch
Three things. First, the Technology-and-Industrials tilt means the tracked universe will largely live or die with the AI-and-automation trade — a concentration worth naming out loud. Second, de-duplicating cross-listings should happen before any sector weighting feeds a strategy, or the weights will be wrong by construction. Third, the long international tail is where coverage gaps and FX effects hide — and, not coincidentally, where differentiated signal is most likely to be found.
