# Is China Tian Lun Gas Holdings Limited's (HKG:1600) 21% ROE Better Than Average?

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 Tian Lun Gas Holdings Limited (HKG:1600).

Our data shows China Tian Lun Gas Holdings has a return on equity of 21% for the last year. One way to conceptualize this, is that for each HK\$1 of shareholders' equity it has, the company made HK\$0.21 in profit.

### How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for China Tian Lun Gas Holdings:

21% = CNÂ¥759m Ã· CNÂ¥3.9b (Based on the trailing twelve months to June 2019.)

Most readers would understand what net profit is, but itâ€™s worth explaining the concept of shareholdersâ€™ equity. 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 Return On Equity Mean?

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. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.

### Does China Tian Lun Gas Holdings Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, China Tian Lun Gas Holdings has a superior ROE than the average (10%) company in the Gas Utilities 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.

### The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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 required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

### China Tian Lun Gas Holdings's Debt And Its 21% ROE

China Tian Lun Gas Holdings does use a significant amount of debt to increase returns. It has a debt to equity ratio of 1.35. There's no doubt the ROE is respectable, but it's worth keeping in mind that metric is elevated by the use of debt. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

### But It's Just One Metric

Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
