Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Xiaomi Corporation (HKG:1810), by way of a worked example.
Over the last twelve months Xiaomi has recorded a ROE of 19%. One way to conceptualize this, is that for each HK$1 of shareholders' equity it has, the company made HK$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 Xiaomi:
19% = CN¥14b ÷ CN¥71b (Based on the trailing twelve months to December 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 Mean?
ROE measures a company's profitability against the profit it retains, and any outside investments. 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 Xiaomi 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Xiaomi has a better ROE than the average (9.0%) in the Tech industry.
That is a good sign. In my book, a high ROE almost always warrants a closer look. For example, I often check if insiders have been buying shares .
How Does Debt Impact ROE?
Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Xiaomi's Debt And Its 19% Return On Equity
While Xiaomi does have some debt, with debt to equity of just 0.15, we wouldn't say debt is excessive. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. 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 Key Takeaway
Return on equity is one way we can compare the business quality of different companies. 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.
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 you might want to take a peek at this data-rich interactive graph of forecasts for the company.
