One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We’ll use ROE to examine Dongjiang Environmental Company Limited (HKG:895), by way of a worked example.
Dongjiang Environmental has a ROE of 13%, based on the last twelve months. That means that for every HK$1 worth of shareholders’ equity, it generated HK$0.13 in profit.

How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Dongjiang Environmental:
13% = 519.74178 ÷ CN¥4.6b (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 Signify?
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 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 it can be interesting to compare the ROE of different companies.
Does Dongjiang Environmental Have A Good ROE?
Arguably the easiest way to assess company’s ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Dongjiang Environmental has a superior ROE than the average (10%) company in the commercial services industry.
That is a good sign. In my book, a high ROE almost always warrants a closer look. One data point to check is if insiders have bought shares recently.
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 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. That will make the ROE look better than if no debt was used.
Dongjiang Environmental’s Debt And Its 13% ROE
While Dongjiang Environmental does have some debt, with debt to equity of just 0.81, we wouldn’t say debt is excessive. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
