What is the Quality of Company (QOC) score?
The QOC score is a 0-10 composite rating derived from 32 fundamental signals across four pillars: profitability (ROE, ROIC, margins), growth (revenue CAGR, earnings acceleration), stability (earnings volatility, debt coverage), and capital efficiency (asset turnover, free cash flow yield).
