How Do These Airlines Boost Their 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. But 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 Delta Air Lines (NYS: DAL) and a few of its sector and industry peers.
Return on Equity
|Delta Air Lines||46.3%||1.3%||0.80||44.50|
|Southwest Airlines (NYS: LUV)||2.5%||1.1%||0.89||2.66|
|United Continental Holdings (NYS: UAL)||1,232.1%||1.8%||1.23||557.63|
|AMR (NYS: AMR)||NM||(4.2%)||0.94||(5.91)|

Things look really unattractive in the airline industry, with low margins dominating this industry. Delta's ROE is driven largely by its massive leverage, rather than by a healthy margin. And the same could be said for United Continental as well. Only Southwest presents something not approaching a nonsensical leverage ratio, and as one of the best operators, it achieves a meager ROE. AMR's negative equity makes the calculation of its ROE impossible.
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. To find more successful investments, dig deeper than the earnings headlines.
