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 Pinnacle West Capital Corporation (NYSE:PNW), by way of a worked example.
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Pinnacle West Capital is:
9.4% = US$566m ÷ US$6.0b (Based on the trailing twelve months to June 2022).
The 'return' refers to a company's earnings over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.09.
Does Pinnacle West Capital Have A Good Return On Equity?
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 Pinnacle West Capital has a similar ROE to the average in the Electric Utilities industry classification (8.9%).
That isn't amazing, but it is respectable. While at least the ROE is not lower than the industry, its still worth checking what role the company's debt plays as high debt levels relative to equity may also make the ROE appear high. If true, then it is more an indication of risk than the potential. You can see the 2 risks we have identified for Pinnacle West Capital by visiting our risks dashboard for free on our platform here.
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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.
Combining Pinnacle West Capital's Debt And Its 9.4% Return On Equity
It's worth noting the high use of debt by Pinnacle West Capital, leading to its debt to equity ratio of 1.29. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
Return on equity is one way we can compare its business quality of different companies. In our books, the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.
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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
