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 Qilu Expressway Company Limited (HKG:1576), by way of a worked example.
Over the last twelve months Qilu Expressway has recorded a ROE of 12%. That means that for every HK$1 worth of shareholders' equity, it generated HK$0.12 in profit.
How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for Qilu Expressway:
12% = CN¥435m ÷ CN¥3.5b (Based on the trailing twelve months to June 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all the money paid into the company from shareholders, plus any earnings retained. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does Return On Equity Mean?
Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Qilu Expressway Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As you can see in the graphic below, Qilu Expressway has a higher ROE than the average (9.7%) in the Infrastructure industry.
That's what I like to see. I usually take a closer look when a company has a better ROE than industry peers. One data point to check is if insiders have bought shares recently.
How Does Debt Impact ROE?
Companies usually need to invest money 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Qilu Expressway's Debt And Its 12% Return On Equity
Although Qilu Expressway does use debt, its debt to equity ratio of 0.13 is still low. 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 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.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free this detailed graph of past earnings, revenue and cash flow.
