To keep the lesson grounded in practicality, we'll use ROE to better understand Boule Diagnostics AB (publ) (STO:BOUL).

Over the last twelve months Boule Diagnostics has recorded a ROE of 14%. One way to conceptualize this, is that for each SEK1 of shareholders' equity it has, the company made SEK0.14 in profit.

How Do I Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Boule Diagnostics:

14% = kr41m ÷ kr301m (Based on the trailing twelve months to December 2018.)

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 the capital paid in by shareholders, plus any retained earnings. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

What Does ROE Mean?

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 ROE can be used to compare two businesses.

Does Boule Diagnostics Have A Good Return On Equity?

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 Boule Diagnostics has an ROE that is roughly in line with the Medical Equipment industry average (13%).

That's neither particularly good, nor bad. ROE doesn't tell us if the share price is low, but it can inform us to the nature of the business. For those looking for a bargain, other factors may be more important. If you like to buy stocks alongside management, then you might just love this free list of companies.

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. 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 Boule Diagnostics's Debt And Its 14% Return On Equity

While Boule Diagnostics does have some debt, with debt to equity of just 0.25, we wouldn't say debt is excessive. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.

The Bottom Line On ROE

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book the highest quality companies have high return on equity, despite low debt. 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. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
