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 S.A.I Leisure Group Company Limited (HKG:1832), by way of a worked example.

S.A.I Leisure Group has a ROE of 10%, 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$0.10 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 S.A.I Leisure Group:

10% = US$10m ÷ US$99m (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 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 ROE Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. 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 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 S.A.I Leisure Group Have A Good Return On Equity?

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 is clear from the image below, S.A.I Leisure Group has a better ROE than the average (8.3%) in the Hospitality industry.

That's what I like to see. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.

Why You Should Consider Debt When Looking At ROE

Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), 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.

Combining S.A.I Leisure Group's Debt And Its 10% Return On Equity

S.A.I Leisure Group is free of net debt, which is a positive for shareholders. Its ROE suggests it is a decent business; and the fact it is not leveraging returns indicates it is well worth watching. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.

But It's Just One Metric

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 around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
