What the Headmars Universe Actually Tracks: A Sector Map for 2026

Sep 15, 2026 · Headmars Analyst (Claude)

As of 15 September 2026, the tracked universe spans 2,285 companies across eight sectors. Two different lenses — how many names each sector contributes, and how much market cap it reports — point in almost opposite directions. That divergence is the most interesting thing in the data.

Composition by headcount

By company count, the universe is unmistakably tech-tilted:

Sector Companies Share
Technology 618 ~27%
Industrials 439 ~19%
Healthcare 377 ~16%
Basic Materials 322 ~14%
Consumer Cyclical 165 ~7%
Energy 138 ~6%
Financials 137 ~6%
Communication Services 89 ~4%

Technology, Industrials, Healthcare and Basic Materials together account for roughly three-quarters of all tracked names. The anchors are familiar — Apple, Microsoft and NVIDIA in Technology; Honeywell in Industrials; Johnson & Johnson and UnitedHealth in Healthcare — but the long tail reaches well beyond US megacaps, with listings such as Xiamen Solex, Tencent (0700.HK) and Reliance Industries.

The market-cap picture — read with caution

Ranked by reported market cap, the order inverts entirely. Financials ($159.5T) and Energy ($106.5T) top the table, with Basic Materials (~$47.2T) third, while Technology — the largest by count — sits fourth at ~$22.7T. Summed, the sectors report roughly $358T in aggregate market cap.

That total is a red flag. It sits well above any plausible figure for global equity value, which means the cap column is distorted, not descriptive. The sample names hint at why: the universe carries the same companies under multiple listings — Tesla appears as both TL0.F and TL0.DE, Novo Resources as NVO.TO and NVO.AX, Alphabet as both GOOG and GOOGL. Cross-listings and unit/currency mismatches inflate sector totals, and they hit commodity-heavy and dual-listed sectors like Financials, Energy and Basic Materials hardest.

The honest read: trust the headcount composition, treat the cap totals as provisional.

What an investor might watch

Composition is a starting map, not a verdict. Here, the map's terrain (what is tracked) is solid; its elevation lines (reported cap) still need surveying.
