Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). To keep the lesson grounded in practicality, we'll use ROE to better understand Avangrid, Inc. (NYSE:AGR).
Over the last twelve months Avangrid has recorded a ROE of 3.7%. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.037 in profit.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Avangrid:
3.7% = US$571m ÷ US$16b (Based on the trailing twelve months to June 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does Return On Equity Mean?
ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.
Does Avangrid Have A Good Return On Equity?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As shown in the graphic below, Avangrid has a lower ROE than the average (9.7%) in the Electric Utilities industry classification.
That certainly isn't ideal. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Nonetheless, it might be wise to check if insiders have been selling.
How Does Debt Impact ROE?
Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Avangrid's Debt And Its 3.7% Return On Equity
While Avangrid does have some debt, with debt to equity of just 0.46, we wouldn't say debt is excessive. Its ROE is rather low, and it does use some debt, albeit not much. That's not great to see. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Bottom Line On ROE
Return on equity is one way we can compare the business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
