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. To keep the lesson grounded in practicality, we'll use ROE to better understand The RMR Group Inc. (NASDAQ:RMR).
Our data shows RMR Group has a return on equity of 14% for the last year. 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 (from continuing operations) ÷ Shareholders' Equity
Or for RMR Group:
14% = US$73m ÷ US$537m (Based on the trailing twelve months to December 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. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does Return On Equity Mean?
ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.
Does RMR Group 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 is clear from the image below, RMR Group has a better ROE than the average (9.1%) in the Real Estate industry.
That's clearly a positive. I usually take a closer look when a company has a better ROE than industry peers. For example, I often check if insiders have been buying shares.
The Importance Of Debt To Return On Equity
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 two cases, the ROE will capture this use of capital to grow. 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.
RMR Group's Debt And Its 14% ROE
One positive for shareholders is that RMR Group does not have any net debt! Its respectable ROE suggests it is a business worth watching, but it's even better the company achieved this without leverage. After all, when a company has a strong balance sheet, it can often find ways to invest in growth, even if it takes some time.
The Bottom Line On ROE
Return on equity is one way we can compare the business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
