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 Cox ABG Group, S.A. (BME:COXG), by way of a worked example.
ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Cox ABG Group is:
11% = €33m ÷ €301m (Based on the trailing twelve months to June 2025).
The 'return' is the income the business earned over the last year. So, this means that for every €1 of its shareholder's investments, the company generates a profit of €0.11.

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see Cox ABG Group has a lower ROE than the average (15%) in the Renewable Energy industry classification.
That's not what we like to see. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved. Our risks dashboard should have the 3 risks we have identified for Cox ABG Group.
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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.
Cox ABG Group clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.69. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
