How Does CVS Caremark Really Boost Its Returns?
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 CVS Caremark (NYS: CVS) and a few of its sector and industry peers:
Return on Equity
Walgreen (NYS: WAG)
Rite Aid (NYS: RAD)
Winn-Dixie Stores (NAS: WINN)

CVS is bested by its rival Walgreen in terms of return on equity, and you can see exactly the key difference: asset turnover. Otherwise, the numbers of these two heavyweights look very similar. Rite Aid turns in negative margins, but even if it had turned a profit, its negative equity would still make ROE incalculable. Winn-Dixie looks similar, sporting high asset turnover and some leverage, but with positive equity.
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.
