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 Resideo Technologies, Inc. (NYSE:REZI), by way of a worked example.
Resideo Technologies has a ROE of 23%, based on the last twelve months. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.23.
How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Resideo Technologies:
23% = US$364m ÷ US$1.6b (Based on the trailing twelve months to June 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. 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 Return On Equity Signify?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.
Does Resideo Technologies 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. Pleasingly, Resideo Technologies has a superior ROE than the average (13%) company in the Building industry.
That's what I like to see. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.
The Importance Of Debt To 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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Resideo Technologies's Debt And Its 23% Return On Equity
While Resideo Technologies does have some debt, with debt to equity of just 0.75, we wouldn't say debt is excessive. Its ROE is very impressive, and given only modest debt, this suggests the business is high quality. 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.
But It's Just One Metric
Return on equity is useful for comparing the quality of different businesses. 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. 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.
