As investors, we need to understand how our companies truly make their money. A neat trick developed for just that purpose -- the DuPont formula -- can help us do so.
The DuPont Formula can give you a better grasp on exactly where your company is producing its profit, and where it might have a competitive advantage. Named after the company where it was pioneered, the formula breaks down return on equity into three components:
Return on equity = net margin x asset turnover x leverage ratio
What makes each of these components important?
High net margins show that a company can get customers to pay more for its products. Luxury-goods companies provide a great example here.
High asset turnover indicates that a company needs to invest less of its capital, since it uses its assets more efficiently to generate sales. Service industries, for instance, often lack big capital investments.
Finally, the leverage ratio shows how much the company is relying on liabilities to create its profits.
Generally, the higher these numbers, the better. That said, too much debt can sink a company, so beware of companies with very high leverage ratios.
Let's see what the DuPont formula can tell us about Trinity Industries (NYS: TRN) and a few of its sector and industry peers:

Wabtec (NYS: WAB)
Ameron International (NYS: AMN)
Valmont Industries (NYS: VMI)

Trinity notches a lackluster ROE, despite using significant leverage. But the company's ROE is otherwise lowered by slow asset turnover and an unimpressive net margin. Westinghouse leads this group with a solid ROE, with a margin that doubles Trinity's and much higher asset turnover, even without significant leverage. In comparison to Wabtec, Valmont uses more leverage, which helps offset the lower asset turnover. Ameron's numbers in each category fall somewhere in the middle of the ranges, as does its ROE.
Using the DuPont formula can often give you some insight into how a company is competing against peers and what type of strategy it's using to juice return on equity.
