How Do I Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Nan Hai:

14% = HK$1.1b ÷ HK$7.0b (Based on the trailing twelve months to December 2018.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. 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 Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. 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 ROE can be used to compare two businesses.

Does Nan Hai 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. 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, Nan Hai has a higher ROE than the average (8.8%) in the Entertainment 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.

How Does Debt Impact 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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Nan Hai's Debt And Its 14% ROE

It's worth noting the significant use of debt by Nan Hai, leading to its debt to equity ratio of 2.87. There's no doubt the ROE is respectable, but it's worth keeping in mind that metric is elevated by the use of debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

The Bottom Line On ROE

Return on equity is one way we can compare the business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. 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.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
