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 STMicroelectronics N.V. (EPA:STM), by way of a worked example.
Our data shows STMicroelectronics has a return on equity of 19% for the last year. That means that for every €1 worth of shareholders’ equity, it generated €0.19 in profit.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for STMicroelectronics:
19% = US$1.2b ÷ US$6.6b (Based on the trailing twelve months to March 2019.)
Most know that net profit is the total earnings after all expenses, but the concept of shareholders’ equity is a little more complicated. 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 ROE 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. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.
Does STMicroelectronics Have A Good ROE?
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. Pleasingly, STMicroelectronics has a superior ROE than the average (11%) company in the Semiconductor industry.
That’s what I like to see. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.
How Does Debt Impact Return On Equity?
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 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.
STMicroelectronics’s Debt And Its 19% ROE
While STMicroelectronics does have some debt, with debt to equity of just 0.33, we wouldn’t say debt is excessive. Its very respectable ROE, combined with only modest debt, suggests the business is in good shape. 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.
The Bottom Line On ROE
Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
But note: STMicroelectronics may not be the best stock to buy. So take a peek at this free list of interesting companies with high ROE and low debt.
