Simply Wall St

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 FONAR Corporation (NASDAQ:FONR).

FONAR has a ROE of 23%, based on the last twelve months. That means that for every $1 worth of shareholders' equity, it generated $0.23 in profit.

How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for FONAR:

23% = US$20m ÷ US$114m (Based on the trailing twelve months to March 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does Return On Equity Mean?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the profit 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. That means ROE can be used to compare two businesses.

Does FONAR Have A Good ROE?

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. As you can see in the graphic below, FONAR has a higher ROE than the average (9.3%) in the Medical Equipment industry.

That's clearly a positive. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.

How Does Debt Impact Return On Equity?

Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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.

FONAR's Debt And Its 23% ROE

Although FONAR does use a little debt, its debt to equity ratio of just 0.0028 is very low. Its ROE is very impressive, and given only modest debt, this suggests the business is high quality. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.

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. All else being equal, a higher ROE is better.

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.
