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 CMS Energy Corporation (NYSE:CMS), by way of a worked example.
Our data shows CMS Energy has a return on equity of 12% for the last year. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.12 in profit.
How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for CMS Energy:
12% = US$583m ÷ US$4.9b (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 the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does Return On Equity 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. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.
Does CMS Energy 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. You can see in the graphic below that CMS Energy has an ROE that is fairly close to the average for the Integrated Utilities industry (10%).
That's neither particularly good, nor bad. ROE doesn't tell us if the share price is low, but it can inform us to the nature of the business. For those looking for a bargain, other factors may be more important. If you are like me, then you will not want to miss this free list of growing companies that insiders are buying.
How Does Debt Impact Return On Equity?
Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. 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. That will make the ROE look better than if no debt was used.
Combining CMS Energy's Debt And Its 12% Return On Equity
CMS Energy clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 2.52. Its ROE is quite good but, it would have probably been lower without the use of 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 one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. 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. 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.
