Does Aena S.M.E Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Aena S.M.E has a better ROE than the average (12%) in the Infrastructure industry.

That's what we like to see. With that said, a high ROE doesn't always indicate high profitability. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, 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 use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Aena S.M.E's Debt And Its 20% ROE

Aena S.M.E does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.17. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. 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 useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
