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 19% for the last year. One way to conceptualize this, is that for each HK$1 of shareholders' equity it has, the company made HK$0.19 in profit.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for China Tian Lun Gas Holdings:
19% = CN¥813m ÷ CN¥4.2b (Based on the trailing twelve months to December 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does ROE Signify?
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, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does China Tian Lun Gas Holdings Have A Good ROE?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, China Tian Lun Gas Holdings has a superior ROE than the average (12%) company in the Gas Utilities industry.
That's clearly a positive. 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.
How Does Debt Impact Return On Equity?
Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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.
Combining China Tian Lun Gas Holdings's Debt And Its 19% Return On Equity
China Tian Lun Gas Holdings clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 1.24. 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 increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
The Key Takeaway
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.
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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
