# Boasting A 26% Return On Equity, Is Nan Nan Resources Enterprise Limited (HKG:1229) A Top Quality Stock?

While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Nan Nan Resources Enterprise Limited (HKG:1229), by way of a worked example.

Over the last twelve months Nan Nan Resources Enterprise has recorded a ROE of 26%. One way to conceptualize this, is that for each HK\$1 of shareholders' equity it has, the company made HK\$0.26 in profit.

### How Do You Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Nan Nan Resources Enterprise:

26% = HK\$48m Ã· HK\$185m (Based on the trailing twelve months to September 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. You can calculate shareholders' equity by subtracting the company's total liabilities from its 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 profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. 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 Nan Nan Resources Enterprise Have A Good ROE?

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 Nan Resources Enterprise has a higher ROE than the average (11%) in the Oil and Gas industry.

That's what I like to see. 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 Return On Equity?

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 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 Nan Resources Enterprise's Debt And Its 26% ROE

Nan Nan Resources Enterprise does use a significant amount of debt to increase returns. It has a debt to equity ratio of 1.47. While the ROE is impressive, that metric has clearly benefited from the company's use of debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

### In Summary

Return on equity is useful for comparing the quality of different businesses. In my book the highest quality companies have high return on equity, despite low debt. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
