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.
