With its stock down 32% over the past month, it is easy to disregard Jiaxing ZMAX Optech (SHSE:688307). But if you pay close attention, you might find that its key financial indicators look quite decent, which could mean that the stock could potentially rise in the long-term given how markets usually reward more resilient long-term fundamentals. Specifically, we decided to study Jiaxing ZMAX Optech's ROE in this article.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How Do You 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 Jiaxing ZMAX Optech is:

3.7% = CN¥30m ÷ CN¥816m (Based on the trailing twelve months to September 2023).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.04 in profit.

What Is The Relationship Between ROE And Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. 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 Jiaxing ZMAX Optech's Earnings Growth And 3.7% ROE

It is hard to argue that Jiaxing ZMAX Optech's ROE is much good in and of itself. Even compared to the average industry ROE of 6.7%, the company's ROE is quite dismal. Jiaxing ZMAX Optech was still able to see a decent net income growth of 9.9% over the past five years. We reckon that there could be other factors at play here. 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.

As a next step, we compared Jiaxing ZMAX Optech's net income growth with the industry and found that the company has a similar growth figure when compared with the industry average growth rate of 11% in the same period.

Earnings growth is a huge factor in stock valuation. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await.

Is Jiaxing ZMAX Optech Efficiently Re-investing Its Profits?

Jiaxing ZMAX Optech has a healthy combination of a moderate three-year median payout ratio of 39% (or a retention ratio of 61%) 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 Jiaxing ZMAX Optech has been growing its earnings, it only recently started to pay dividends which likely means that the company decided to impress new and existing shareholders with a dividend.

Conclusion

Overall, we feel that Jiaxing ZMAX Optech certainly does have some positive factors to consider. With a high rate of reinvestment, albeit at a low ROE, the company has managed to see a considerable growth in its earnings.
