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 China Risun Group Limited (HKG:1907).

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

Return on equity 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 China Risun Group is:

21% = CN¥2.6b ÷ CN¥13b (Based on the trailing twelve months to June 2022).

The 'return' is the income the business earned over the last year. Another way to think of that is that for every HK$1 worth of equity, the company was able to earn HK$0.21 in profit.

Does China Risun Group Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in 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 you can see in the graphic below, China Risun Group has a higher ROE than the average (12%) in the Chemicals industry.

That's what we like to see. However, bear in mind that a high ROE doesn't necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

China Risun Group's Debt And Its 21% ROE

China Risun Group clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.59. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

Conclusion

Return on equity is one way we can compare its business quality of different companies. 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.

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 I think it may be worth checking this free this detailed graph of past earnings, revenue and cash flow.
