How this is calculated

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

Profitability (25%) — Loss Ratio, Loss Ratio Trend
Capital Efficiency (15%) — 5yr Avg ROE, 5yr Share-Count CAGR
Growth Quality (10%) — 5yr Premium CAGR, Loss Ratio Trend (growth quality check), Revenue-Growth Years (5)
Cash Generation (15%) — Reserve Development, Loss Ratio Stability (σ)
Balance Sheet (25%) — Premiums / Surplus, Interest Coverage (EBIT/Int)
Stability (10%) — EPS Volatility (σ/μ), Negative-Revenue Years (5), Piotroski F-Score

The six pillars read only reported financial-statement fields — no analyst targets or consensus ratings. The archetype that picks which pillar formulas apply is not fully price-free, though: it can route a company to the distressed/ungradable archetype based on price vs. its 52-week high, and beta affects one classification check. A minimum of 5 fiscal years of audited statements is required. Insurers and banks are graded on their own methodology — insurers on loss ratio, its trend and stability, and premiums-to-surplus; banks on the efficiency ratio, its trend and stability, and equity-to-assets — rather than on industrial margin/ROIC signals. Distressed, highly leveraged infrastructure, asset-manager, and other financial businesses are declared ungradable rather than forced into a numeric score.
