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 Compumedics Limited (ASX:CMP), by way of a worked example.
Over the last twelve months Compumedics has recorded a ROE of 15%. Another way to think of that is that for every A$1 worth of equity in the company, it was able to earn A$0.15.
How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for Compumedics:
15% = AU$4.0m ÷ AU$27m (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 all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does Return On Equity Mean?
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. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Compumedics Have A Good Return On Equity?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. 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 Compumedics has an ROE that is fairly close to the average for the Medical Equipment industry (12%).
That's not overly surprising. ROE tells us about the quality of the business, but it does not give us much of an idea if the share price is cheap. 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. 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 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 Compumedics's Debt And Its 15% Return On Equity
Although Compumedics does use a little debt, its debt to equity ratio of just 0.057 is very low. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.
The Bottom Line On ROE
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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 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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
