Should We Be Delighted With TAG Immobilien AG's (ETR:TEG) ROE Of 20%?

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 TAG Immobilien AG (ETR:TEG).

How To Calculate Return On Equity?

ROE 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 TAG Immobilien is:

20% = €576m ÷ €2.9b (Based on the trailing twelve months to September 2021).

The 'return' is the amount earned after tax over the last twelve months. So, this means that for every €1 of its shareholder's investments, the company generates a profit of €0.20.

Does TAG Immobilien 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. As you can see in the graphic below, TAG Immobilien has a higher ROE than the average (10%) in the Real Estate industry.

That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

How Does Debt Impact ROE?

Virtually all companies need money to invest in the business, to grow 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 used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

TAG Immobilien's Debt And Its 20% ROE

It's worth noting the high use of debt by TAG Immobilien, leading to its debt to equity ratio of 1.06. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Summary

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 the same ROE, then I would generally prefer the one with less debt.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
