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). To keep the lesson grounded in practicality, we'll use ROE to better understand Just Life Group Limited (NZSE:JLG).
Over the last twelve months Just Life Group has recorded a ROE of 15%. Another way to think of that is that for every NZ$1 worth of equity in the company, it was able to earn NZ$0.15.
How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Just Life Group:
15% = NZ$2.1m ÷ NZ$14m (Based on the trailing twelve months to December 2018.)
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. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE Signify?
ROE measures a company's profitability against the profit it retains, and any outside investments. 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 Just Life Group 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. You can see in the graphic below that Just Life Group has an ROE that is fairly close to the average for the Specialty Retail industry (14%).
That isn't amazing, but it is respectable. 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 ROE?
Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. 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.
Just Life Group's Debt And Its 15% ROE
While Just Life Group does have some debt, with debt to equity of just 0.82, we wouldn't say debt is excessive. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Key Takeaway
Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
