One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We’ll use ROE to examine Amiad Water Systems Ltd (LON:AFS), by way of a worked example.
Our data shows Amiad Water Systems has a return on equity of 5.6% for the last year. Another way to think of that is that for every £1 worth of equity in the company, it was able to earn £0.056.
How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Amiad Water Systems:
5.6% = US$2m ÷ US$60m (Based on the trailing twelve months to June 2018.)
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. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE Mean?
ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. That means it can be interesting to compare the ROE of different companies.
Does Amiad Water Systems 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, Amiad Water Systems has a lower ROE than the average (13%) in the machinery industry.
Unfortunately, that’s sub-optimal. We prefer it when the ROE of a company is above the industry average, but it’s not the be-all and end-all if it is lower. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
Why You Should Consider Debt When Looking At ROE
Virtually all companies need money to invest in the business, to grow 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 required for growth will boost returns, but will not impact the shareholders’ equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Amiad Water Systems’s Debt And Its 5.6% Return On Equity
Although Amiad Water Systems does use debt, its debt to equity ratio of 0.42 is still low. I’m not impressed with its ROE, but the debt levels are not too high, indicating the business has decent prospects. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.
Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.
But when a business is high quality, the market often bids it up to a price that reflects this. 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.
