The Lay of the Land
As of June 2, 2026, the Headmars tracked universe spans 180 companies across eight sectors. Technology leads in raw company count (44), followed by Consumer Cyclical (26), Healthcare and Energy (21 each), Basic Materials (19), Consumer Defensive and Industrials (18 each), and Communication Services (13). Count alone, however, is a poor proxy for economic weight — and that gap is where the most interesting story lives.
Technology: The Broadest Tent
With 44 names, Technology commands nearly a quarter of the entire tracked universe. The sample roster — Apple, Microsoft, NVIDIA, AMD, Salesforce, Intel — spans chip designers, cloud hyperscalers, enterprise software, and legacy hardware in a single bucket. That breadth is intentional: the sector captures the full AI infrastructure stack, from silicon (NVDA, AMD) through platforms (MSFT, CRM) to end-device (AAPL). Investors watching this cohort should expect diverging earnings trajectories as capital expenditure on AI infrastructure compounds while application-layer monetisation remains uneven.
Communication Services: Fewer Names, Outsized Weight
Communication Services holds just 13 companies — the smallest sector by count — yet its reported aggregate market capitalisation of $4.6 trillion dwarfs every other sector with available data. Alphabet (tracked under both GOOGL and GOOG), Meta Platforms, Netflix, Tencent, and Walt Disney anchor the group. This concentration means a handful of earnings reports can swing the sector's aggregate figures materially. The presence of Tencent (0700.HK) alongside the US-listed names also introduces meaningful geopolitical and regulatory variance — a dimension that purely domestic trackers miss.
Healthcare and Energy: The Mid-Tier Pillars
Healthcare and Energy each count 21 names, with partial market-cap data of $1.3 trillion and $1.17 trillion respectively. Healthcare spans US insurance giants (UnitedHealth), pharmaceutical majors (Johnson & Johnson, AbbVie), consumer health platforms (GoodRx), and smaller biotech names from China and South Korea — a blend of defensive incumbents and speculative growth. Energy shows a similarly wide latitude: Exxon Mobil and Shell represent supermajor integrated oil, Reliance Industries adds emerging-market exposure, and mid-cap names like Antero Resources introduce domestic natural gas leverage. The sector's global spread — US, UK, India, Canada — means currency moves and regional energy policy can drive meaningful divergence across otherwise correlated holdings.
Consumer Defensive and the Micro-Cap Edges
Consumer Defensive (18 companies) assembles some of the most recognisable global brands: Walmart, Procter & Gamble, Coca-Cola, PepsiCo, Costco, and Nestlé. These names serve as natural ballast against the growth-heavy Technology and Communication Services weightings. Basic Materials (19) and Industrials (18), by contrast, contain the universe's highest proportion of micro-cap and non-US names — lithium juniors, gold explorers listed on multiple exchanges, and Chinese industrial names — carrying wider liquidity risk and higher dispersion of outcome.
Three Things to Watch
Concentration in Communication Services. Thirteen names at $4.6 trillion in tracked capitalisation means single-stock events — a regulatory ruling, a missed quarter — register at the sector aggregate level. Monitor those 13 names with outsized attention relative to their count.
Cross-listing duplication. Tesla, Alphabet, Obsidian Energy, and Novo Resources each appear under multiple tickers across different exchanges. Naive position aggregation will double-count exposure; portfolio-level analysis requires deduplication before drawing weight conclusions.
Currency and market-hours dispersion. Names span the NYSE, NASDAQ, HKEX, BSE, Frankfurt, TSX, ASX, and TWSE. Investors need a consistent FX base and awareness of non-overlapping trading sessions to interpret intraday signals coherently across the full universe.
