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 Enerplus Corporation (TSE:ERF).
Over the last twelve months Enerplus has recorded a ROE of 21%. Another way to think of that is that for every CA$1 worth of equity in the company, it was able to earn CA$0.21.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for Enerplus:
21% = CA$419m ÷ CA$2.0b (Based on the trailing twelve months to September 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does ROE Signify?
ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit over the last twelve months. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does Enerplus Have A Good ROE?
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. Pleasingly, Enerplus has a superior ROE than the average (7.3%) company in the Oil and Gas industry.
That is a good sign. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.
Why You Should Consider Debt When Looking At ROE
Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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.
Enerplus's Debt And Its 21% ROE
While Enerplus does have some debt, with debt to equity of just 0.32, we wouldn't say debt is excessive. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. 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 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 around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
