UK Mid-Cap Quality 25

Twenty-five FTSE 250 names with ROIC above 15%, leverage below 1.5x and 5-year revenue growth above 7%, capped at 6% per name.

Why it won

The FTSE 250 has been the most-discounted developed-market mid-cap index for three years, but quality dispersion inside it is enormous. This screen carves out the genuine compounders from the structurally challenged names dragging the headline index down. It is the most-saved UK-themed prompt on the platform.

The prompt

FTSE 250 quality index. ROIC above 15%, net debt to EBITDA below 1.5x, 5-year revenue CAGR above 7%, gross margin above 30%. 25 names, weighted by ROIC capped at 6%.

Methodology

  • Universe: current FTSE 250 constituents, excluding investment trusts and SPACs.
  • Quality screen: 5-year average ROIC above 15%.
  • Balance-sheet screen: net debt to EBITDA below 1.5x.
  • Growth screen: 5-year revenue CAGR above 7%, gross margin above 30%.
  • Weight by ROIC ranking, capped at 6% per name, rebalanced annually in May.

5-year backtest in GBP beats the FTSE 250 by 5.8% annualised and trails SPY-GBP by about 1%, with much better drawdown behaviour than the parent index.

Risks

  • FTSE 250 is structurally exposed to UK domestic consumer and housing cycles.
  • Several names (Games Workshop, Greggs) have low free float and can be illiquid at scale.
  • ROIC weighting can favour asset-light businesses that screen well but carry brand-concentration risk.
