Quality Compounders ex-Tech 30

Thirty global compounders with ROIC above 20% and zero exposure to the Magnificent Seven, on a 5-year backtest that quietly clears SPY.

Why it won

Most quality screens become tech screens by accident, because tech dominates the high-ROIC tail. This thesis caps that off and forces the screen to surface the older, less-discussed compounders that hide behind the GICS Technology label. The cap-weighted backtest is competitive with SPY without owning Apple or Microsoft, which is the rare case where 'ex-tech' is a feature, not a handicap.

The prompt

Build me a 30-stock global equity index of quality compounders, excluding GICS Information Technology and Communication Services. Screen for 5-year average ROIC above 20%, 10-year revenue CAGR above 6%, net debt to EBITDA below 1.5x, and gross margin above 40%. Cap-weight, max 6% per name, rebalance annually.

Methodology

  • Universe: global developed-market large and mid caps with market cap above 5bn USD.
  • Quality screen: 5-year average ROIC above 20% AND 10-year revenue CAGR above 6%.
  • Balance-sheet screen: net debt to EBITDA below 1.5x, interest coverage above 10x.
  • Sector exclusion: GICS Information Technology and Communication Services entirely removed.
  • Cap-weight with a 6% per-name ceiling, rebalance annually in March.

Risks

  • Concentration in payment networks and rating agencies, which share regulatory and economic-cycle exposure.
  • Quality screens are notoriously crowded, valuations can compress quickly in a risk-on rotation.
  • Excluding tech means missing the dominant earnings-growth engine of the last decade if that pattern continues.
