Zhongjin Irradiation (SZSE:300962) has had a great run on the share market with its stock up by a significant 11% over the last three months. As most would know, fundamentals are what usually guide market price movements over the long-term, so we decided to look at the company's key financial indicators today to determine if they have any role to play in the recent price movement. In this article, we decided to focus on Zhongjin Irradiation's ROE.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

The formula for ROE is:

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

So, based on the above formula, the ROE for Zhongjin Irradiation is:

11% = CN¥103m ÷ CN¥946m (Based on the trailing twelve months to September 2022).

The 'return' refers to a company's earnings over the last year. So, this means that for every CN¥1 of its shareholder's investments, the company generates a profit of CN¥0.11.

What Has ROE Got To Do With Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Assuming all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

A Side By Side comparison of Zhongjin Irradiation's Earnings Growth And 11% ROE

At first glance, Zhongjin Irradiation's ROE doesn't look very promising. However, given that the company's ROE is similar to the average industry ROE of 9.8%, we may spare it some thought. On the other hand, Zhongjin Irradiation reported a moderate 17% net income growth over the past five years. Given the slightly low ROE, it is likely that there could be some other aspects that are driving this growth. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio.

We then compared Zhongjin Irradiation's net income growth with the industry and we're pleased to see that the company's growth figure is higher when compared with the industry which has a growth rate of 8.9% in the same period.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. This then helps them determine if the stock is placed for a bright or bleak future. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Zhongjin Irradiation is trading on a high P/E or a low P/E, relative to its industry.

Is Zhongjin Irradiation Making Efficient Use Of Its Profits?

Zhongjin Irradiation has a healthy combination of a moderate three-year median payout ratio of 33% (or a retention ratio of 67%) and a respectable amount of growth in earnings as we saw above, meaning that the company has been making efficient use of its profits.

While Zhongjin Irradiation has seen growth in its earnings, it only recently started to pay a dividend. It is most likely that the company decided to impress new and existing shareholders with a dividend.

Conclusion

Overall, we feel that Zhongjin Irradiation certainly does have some positive factors to consider. Even in spite of the low rate of return, the company has posted impressive earnings growth as a result of reinvesting heavily into its business. While we won't completely dismiss the company, what we would do, is try to ascertain how risky the business is to make a more informed decision around the company.
