How this is calculated

AlphaQuality grades six pillars from 0-100 and weights each by archetype:

Profitability (25%) — 5yr Avg ROIC, Operating Margin Trend
Capital Efficiency (15%) — 5yr Avg ROE, 5yr Share-Count CAGR
Growth Quality (25%) — 5yr Revenue CAGR, 5yr EPS CAGR, Revenue-Growth Years (5)
Cash Generation (20%) — 5yr FCF Margin, 5yr FCF/NI Conversion
Balance Sheet (10%) — Net Debt / EBITDA, Interest Coverage (EBIT/Int), Altman Z-Score
Stability (5%) — EPS Volatility (σ/μ), Piotroski F-Score, Negative-Revenue Years (5)

We deliberately ignore stock price, analyst targets, and consensus ratings so the grade is suitable for backtesting forward returns. A minimum of 5 fiscal years of audited statements is required; distressed and highly leveraged infrastructure businesses are declared ungradable rather than forced into a numeric score.
