One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We'll use ROE to examine BayWa Aktiengesellschaft (FRA:BYW), by way of a worked example.
BayWa has a ROE of 4.4%, based on the last twelve months. One way to conceptualize this, is that for each €1 of shareholders' equity it has, the company made €0.044 in profit.
How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for BayWa:
4.4% = €37m ÷ €1.4b (Based on the trailing twelve months to March 2019.)
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 all the money paid into the company from shareholders, plus any earnings retained. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.
What Does ROE Signify?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does BayWa 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. As shown in the graphic below, BayWa has a lower ROE than the average (11%) in the Trade Distributors industry classification.
That's not what we like to see. 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. Nonetheless, it might be wise to check if insiders have been selling.
The Importance Of Debt To Return On Equity
Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, 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 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.
BayWa's Debt And Its 4.4% ROE
BayWa clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 2.98. While the ROE isn't too bad, it would probably be a lot lower if the company was forced to reduce debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
But It's Just One Metric
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. All else being equal, a higher ROE is better.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
