DuPont Analysis is a powerful financial decomposition framework that breaks down a company's Return on Equity (ROE) into its three fundamental component drivers — net profit margin (profitability), asset turnover (efficiency), and financial leverage (equity multiplier) — using the formula: ROE = Net Profit Margin × Asset Turnover × Equity Multiplier. Originally developed by the DuPont Corporation in the 1920s, this framework allows analysts to identify precisely which factor is driving a company's ROE — whether it is superior profit margins, efficient asset utilisation, or financial leverage — and how changes in each component affect overall returns. An extended five-factor DuPont model further decomposes net profit margin into tax burden, interest burden, and EBIT margin. For equity analysts and investors on Ventura Securities, DuPont Analysis is an indispensable tool for comparing ROE quality across companies within a sector, distinguishing sustainably high-quality earnings from leverage-inflated returns, and tracking the drivers of ROE improvement or deterioration over time.
