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 China Oriental Group Company Limited (HKG:581), by way of a worked example.

Over the last twelve months China Oriental Group has recorded a ROE of 27%. Another way to think of that is that for every HK$1 worth of equity in the company, it was able to earn HK$0.27.

How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for China Oriental Group:

27% = CN¥4.8b ÷ CN¥18b (Based on the trailing twelve months to December 2018.)

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 Mean?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

Does China Oriental Group 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, China Oriental Group has a higher ROE than the average (9.1%) in the Metals and Mining industry.

That's clearly a positive. In my book, a high ROE almost always warrants a closer look. One data point to check is if insiders have bought shares recently.

Why You Should Consider Debt When Looking At 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining China Oriental Group's Debt And Its 27% Return On Equity

Although China Oriental Group does use debt, its debt to equity ratio of 0.16 is still low. When I see a high ROE, fuelled by only modest debt, I suspect the business is high quality. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.

The Key Takeaway

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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.
