Healthcare ex-China 30

Thirty global healthcare names with under 10% China revenue exposure and no Chinese supply chain dependence above 20% of API sourcing.

Why it won

Healthcare investors have spent two years trying to size and dodge biosecurity-driven China decoupling risk. This index does it explicitly, screening for both end-market China exposure AND API supply-chain exposure, and produces a basket that captures the core healthcare thesis without the geopolitical overhang. Useful as a paired short of MCHI for the more aggressive sleeves.

The prompt

Global healthcare index excluding any company with more than 10% of revenue from China or more than 20% of API supply chain sourced in China. 30 names, sub-industry diversified, weighted by 3-year FCF growth.

Methodology

  • Universe: developed-market healthcare names above 10bn USD market cap.
  • China end-market screen: trailing 12m China revenue exposure must be below 10%.
  • Supply chain screen: API sourcing from China must be disclosed and below 20% of materials.
  • Sub-industry diversification: pharma 35%, medtech 25%, services 15%, biotech 15%, distribution 10%.
  • Weight by 3-year FCF growth, capped at 6% per name, annual rebalance.

Backtest

Period: Mar 2021 to Mar 2026 (5Y)
5-year backtest trails SPY by 0.4% annualised but beats XLV by 2.1%, with a 4-point smaller drawdown than the broader healthcare benchmark.

Risks

  • GLP-1 cluster (Novo Nordisk, Lilly) is a meaningful concentration that drives a large share of recent alpha.
  • Pharma pricing reform headlines remain the single largest single-day drawdown driver historically.
  • China API supply-chain data is self-reported and reshoring claims are uneven across the universe.
