What Is Why ROE Matters and How to Screen for High-ROE Stocks?
Return on equity (ROE) measures how efficiently a company generates profits from shareholder capital. A 20% ROE means the company generates $0.20 of profit for every $1.00 of equity. Sustained high ROE indicates competitive advantage, pricing power, and efficient capital allocation.
Why It Matters
However, ROE can be artificially inflated through excessive leverage. A company with 30% ROE but 5:1 debt-to-equity may be achieving returns through borrowed money rather than operational excellence. The DuPont decomposition separates ROE into profit margin, asset turnover, and leverage components for deeper analysis.
How LyraIQ Approaches This
LyraIQ's ROE screener uses the DuPont framework to identify companies with high ROE driven primarily by profit margins and asset turnover rather than leverage. The system requires ROE > 15%, ROE stability (coefficient of variation < 0.25 over 5 years), and debt-to-equity < 1.0 to ensure sustainable capital efficiency.
Practical Steps
- Calculate DuPont decomposition: ROE = Margin × Turnover × Leverage
- Target ROE > 15% with margin and turnover as primary drivers
- Check ROE stability over 5 years — avoid volatile performers
- Verify debt-to-equity < 1.0 to exclude leverage-driven ROE
- Compare ROE to sector medians for relative assessment
