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. We'll use ROE to examine Meggitt PLC (LON:MGGT), by way of a worked example.
Over the last twelve months Meggitt has recorded a ROE of 6.0%. One way to conceptualize this, is that for each £1 of shareholders' equity it has, the company made £0.060 in profit.
How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Meggitt:
6.0% = UK£145m ÷ UK£2.4b (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 earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does Return On Equity 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. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does Meggitt 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As shown in the graphic below, Meggitt has a lower ROE than the average (11%) in the Aerospace & Defense industry classification.
That certainly isn't ideal. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Nonetheless, it might be wise to check if insiders have been selling.
How Does Debt Impact Return On Equity?
Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Meggitt's Debt And Its 6.0% ROE
Although Meggitt does use debt, its debt to equity ratio of 0.47 is still low. Its ROE isn't particularly impressive, but the debt levels are quite modest, so the business probably has some real potential. 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 Key Takeaway
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 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
