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). To keep the lesson grounded in practicality, we'll use ROE to better understand China SCE Group Holdings Limited (HKG:1966).

China SCE Group Holdings has a ROE of 15%, based on the last twelve months. One way to conceptualize this, is that for each HK$1 of shareholders' equity it has, the company made HK$0.15 in profit.

How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

Or for China SCE Group Holdings:

15% = CN¥3.8b ÷ CN¥25b (Based on the trailing twelve months to June 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 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. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.

Does China SCE Group Holdings 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. As you can see in the graphic below, China SCE Group Holdings has a higher ROE than the average (8.5%) in the Real Estate industry.

That's what I like to see. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares.

How Does Debt Impact ROE?

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
