Why it matters
ROE is a primary metric to assess management efficiency. High-quality businesses (compounding machines) typically maintain an ROE above 15% to 20% over long periods, showing they can generate high returns on reinvested earnings without needing heavy capital injections.

Common Mistakes
Ignoring the impact of debt leverage
A company can achieve a high ROE of 30% simply by borrowing heavily (high liabilities, low equity). This leverage increases financial risk. Always check the Debt-to-Equity ratio alongside ROE to ensure the return is not driven by excessive risk.
📖 Real-World Example: Efficient consumer compounder
A major beverage company maintains an ROE of 35% by leveraging its strong brand, high operating margins, and low capital requirements. It consistently generates high profits on a small asset base, allowing it to pay dividends and buy back shares, creating substantial long-term value.
