While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Ameren Corporation (NYSE:AEE), by way of a worked example.
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Ameren is:
10% = US$964m ÷ US$9.3b (Based on the trailing twelve months to March 2021).
The 'return' is the income the business earned over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.10 in profit.
Does Ameren 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. You can see in the graphic below that Ameren has an ROE that is fairly close to the average for the Integrated Utilities industry (9.3%).
That's neither particularly good, nor bad. While at least the ROE is not lower than the industry, its still worth checking what role the company's debt plays as high debt levels relative to equity may also make the ROE appear high. If true, then it is more an indication of risk than the potential. To know the 3 risks we have identified for Ameren visit our risks dashboard for free.
The Importance Of Debt To Return On Equity
Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.
Ameren's Debt And Its 10% ROE
Ameren clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.33. The combination of a rather low ROE and significant use of debt is not particularly appealing. 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.
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
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. So I think it may be worth checking this free report on analyst forecasts for the company.
