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). By way of learning-by-doing, we'll look at ROE to gain a better understanding of Jiangsu Zhongsheng Gaoke Environmental Co.,Ltd. (SZSE:002778).

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

ROE can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Jiangsu Zhongsheng Gaoke EnvironmentalLtd is:

4.8% = CN¥30m ÷ CN¥620m (Based on the trailing twelve months to September 2022).

The 'return' refers to a company's earnings over the last year. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.05 in profit.

Does Jiangsu Zhongsheng Gaoke EnvironmentalLtd Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for 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, Jiangsu Zhongsheng Gaoke EnvironmentalLtd has a lower ROE than the average (6.9%) in the Chemicals industry.

That certainly isn't ideal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

How Does Debt Impact ROE?

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 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Jiangsu Zhongsheng Gaoke EnvironmentalLtd's Debt And Its 4.8% Return On Equity

While Jiangsu Zhongsheng Gaoke EnvironmentalLtd does have some debt, with a debt to equity ratio of just 0.49, we wouldn't say debt is excessive. Its ROE is certainly on the low side, and since it already uses debt, we're not too excited about the company. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.
