Return on equity is the metric everyone watches, but the single number hides what's actually driving returns. DuPont analysis decomposes ROE into three components: profit margin, asset turnover, and financial leverage. Understanding which levers a company pulls to generate returns changes everything about how you evaluate it.
Two companies might both deliver 15% ROE, but one achieves it through high margins and low leverage while the other uses thin margins, fast asset turnover, and significant debt. Those are fundamentally different business models with different risk profiles.
This course teaches you to perform three-factor and five-factor DuPont analysis, interpret what each component reveals, and track how companies shift their strategies over time. You'll see how retail companies typically rely on asset turnover, luxury brands on profit margins, and some companies dangerously on leverage alone.
The components interact
What makes DuPont analysis powerful is seeing how the factors trade off. A company might accept lower margins to increase turnover, or boost leverage when organic profit growth slows. You'll learn to identify sustainable versus unsustainable ROE improvements—cutting costs boosts margins but has limits, while revenue growth from genuine competitive advantages can compound for years.
We work through cases where DuPont analysis predicted performance inflection points. One example tracks a manufacturer whose ROE held steady at 12% for three years, but decomposition showed margin expansion masking declining asset turnover—a warning sign that proved accurate when growth stalled.
ROE tells you the outcome. DuPont tells you how they got there.
You'll build models that decompose ROE for multiple companies simultaneously, creating comparison frameworks that reveal strategic positioning and operational efficiency differences across competitors.
