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). We'll use ROE to examine Trinity Industries, Inc. (NYSE:TRN), by way of a worked example.
Trinity Industries has a ROE of 4.9%, 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 $0.049.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Trinity Industries:
4.9% = US$121m ÷ US$2.6b (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 the money paid into the company from shareholders, plus any earnings retained. 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 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. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. That means it can be interesting to compare the ROE of different companies.
Does Trinity Industries Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see Trinity Industries has a lower ROE than the average (14%) in the Machinery industry classification.
That certainly isn't ideal. 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 could be useful to double-check if insiders have sold shares recently.
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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Trinity Industries's Debt And Its 4.9% Return On Equity
Trinity Industries clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 1.77. Its ROE isn't too bad, but it would probably be very disappointing if the company had to stop using debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
The Key Takeaway
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. If two companies have the same ROE, then I would generally prefer the one with less debt.
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.
