What Is What Is a Stock Quality Score and How Is It Calculated??
A stock quality score is a composite metric that evaluates multiple dimensions of business quality simultaneously. Common inputs include earnings stability, balance sheet strength, profitability consistency, competitive moat indicators, and governance quality. Scores typically range from 0-100, with higher scores indicating stronger underlying businesses.
Why It Matters
Quality investing has historically outperformed over long periods with lower volatility. The 'quality factor' is one of the most persistent and robust sources of excess returns in academic finance, delivering 2-3% annual outperformance with lower drawdowns than the broad market.
How LyraIQ Approaches This
LyraIQ's quality score combines 12 sub-metrics: earnings consistency (coefficient of variation < 0.25), ROE stability (> 15% for 5+ years), debt discipline (debt/equity < 1.0), margin durability, cash conversion (> 0.8), revenue predictability, insider ownership, institutional confidence, analyst consistency, ESG fundamentals, audit quality, and governance transparency. Each sub-metric is weighted based on historical predictive power.
Practical Steps
- Calculate earnings consistency using 5-year coefficient of variation
- Check ROE stability — requires > 15% for 5+ consecutive years
- Verify cash conversion ratio > 0.8 for earnings quality
- Assess balance sheet strength: debt/equity < 1.0, current ratio > 1.5
