While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. By way of learning-by-doing, we'll look at ROE to gain a better understanding of QinetiQ Group plc (LON:QQ.).
QinetiQ Group has a ROE of 15%, based on the last twelve months. One way to conceptualize this, is that for each £1 of shareholders' equity it has, the company made £0.15 in profit.
How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for QinetiQ Group:
15% = UK£124m ÷ UK£808m (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. 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 yearly profit. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does QinetiQ 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. Pleasingly, QinetiQ Group has a superior ROE than the average (9.2%) company in the Aerospace & Defense industry.
That's clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares .
The Importance Of Debt To Return On Equity
Companies usually need to invest money 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
QinetiQ Group's Debt And Its 15% ROE
One positive for shareholders is that QinetiQ Group does not have any net debt! Its solid ROE indicates a good business, especially when you consider it is not using leverage. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.
But It's Just One Metric
Return on equity is useful for comparing the quality of different businesses. 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. So I think it may be worth checking this free report on analyst forecasts for the company.
