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 Dominion Energy, Inc. (NYSE:D), by way of a worked example.
Our data shows Dominion Energy has a return on equity of 3.3% for the last year. That means that for every $1 worth of shareholders' equity, it generated $0.03 in profit.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Dominion Energy:
3.3% = US$869m ÷ US$28b (Based on the trailing twelve months to June 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. 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 ROE Signify?
Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the profit over the last twelve months. 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 Dominion Energy 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see Dominion Energy has a lower ROE than the average (10%) in the Integrated Utilities industry classification.
That's not what we like to see. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Still, shareholders might want to check if insiders have been selling.
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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Dominion Energy's Debt And Its 3.3% Return On Equity
Dominion Energy does use a significant amount of debt to increase returns. It has a debt to equity ratio of 1.48. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. 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 Bottom Line On ROE
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 when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
