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 Arotech Corporation (NASDAQ:ARTX), by way of a worked example.
Over the last twelve months Arotech has recorded a ROE of 8.0%. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.080.
How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Arotech:
8.0% = 5.82848 ÷ US$73m (Based on the trailing twelve months to September 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. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.
What Does Return On Equity Signify?
ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.
Does Arotech 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 shown in the graphic below, Arotech has a lower ROE than the average (14%) in the Aerospace & Defense industry classification.
Unfortunately, that’s sub-optimal. It is better when the ROE is above industry average, but a low one doesn’t necessarily mean the business is overpriced. Still, shareholders might want to check if insiders have been selling.
Why You Should Consider Debt When Looking At ROE
Most companies need money — from somewhere — to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
Arotech’s Debt And Its 8.0% ROE
While Arotech does have some debt, with debt to equity of just 0.19, we wouldn’t say debt is excessive. I’m not impressed with its ROE, but the debt levels are not too high, indicating the business has decent prospects. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Bottom Line On ROE
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. 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 I think it may be worth checking this free report on analyst forecasts for the company.
