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 VINCI SA (EPA:DG), by way of a worked example.
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.
How Is ROE Calculated?
Return on equity can be calculated by using the formula:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for VINCI is:
4.4% = €1.0b ÷ €23b (Based on the trailing twelve months to December 2020).
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 €0.04 in profit.
Does VINCI 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. The image below shows that VINCI has an ROE that is roughly in line with the Construction industry average (4.4%).
So while the ROE is not exceptional, at least its acceptable. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels. If a company takes on too much debt, it is at higher risk of defaulting on interest payments. Our risks dashboardshould have the 3 risks we have identified for VINCI.
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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Combining VINCI's Debt And Its 4.4% Return On Equity
It's worth noting the high use of debt by VINCI, leading to its debt to equity ratio of 1.36. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
