That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance.

Our risks dashboardshould have the 2 risks we have identified for Companhia Energética do Rio Grande do Norte - COSERN.

How Does Debt Impact ROE?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Companhia Energética do Rio Grande do Norte - COSERN's Debt And Its 35% ROE

Companhia Energética do Rio Grande do Norte - COSERN does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.42. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
