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). We’ll use ROE to examine Bouygues SA (EPA:EN), by way of a worked example.
Our data shows Bouygues has a return on equity of 13% for the last year. Another way to think of that is that for every €1 worth of equity in the company, it was able to earn €0.13.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Bouygues:
13% = €1.1b ÷ €9.9b (Based on the trailing twelve months to June 2018.)
Most know that net profit is the total earnings after all expenses, but the concept of shareholders’ equity is a little more complicated. It is the capital paid in by shareholders, plus any retained earnings. 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 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. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.
Does Bouygues Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. The image below shows that Bouygues has an ROE that is roughly in line with the construction industry average (13%).
That’s not overly surprising. Of course, this year’s ROE might be a product of last year’s decisions. So I like to check the tenure of the board and CEO, before reaching any conclusions.
The Importance Of Debt To Return On Equity
Companies usually need to invest money to grow their 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 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.
Bouygues’s Debt And Its 13% ROE
While Bouygues does have some debt, with debt to equity of just 0.76, 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.
Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.
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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
