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 DocCheck AG (ETR:AJ91).
Over the last twelve months DocCheck has recorded a ROE of 14%. That means that for every €1 worth of shareholders' equity, it generated €0.14 in profit.

How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for DocCheck:
14% = €2.9m ÷ €20m (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?
Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.
Does DocCheck Have A Good Return On Equity?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, DocCheck has a lower ROE than the average (25%) in the Healthcare Services industry.
That certainly isn't ideal. We prefer it when the ROE of a company is above the industry average, but it's not the be-all and end-all if it is lower. Still, shareholders might want to check if insiders have been selling.
How Does Debt Impact ROE?
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 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
