Zhejiang Dingli MachineryLtd (SHSE:603338) has had a great run on the share market with its stock up by a significant 27% over the last three months. Given that the market rewards strong financials in the long-term, we wonder if that is the case in this instance. Particularly, we will be paying attention to Zhejiang Dingli MachineryLtd's ROE today.

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. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How To Calculate Return On Equity?

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 Zhejiang Dingli MachineryLtd is:

21% = CN¥1.7b ÷ CN¥8.1b (Based on the trailing twelve months to September 2023).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every CN¥1 worth of equity, the company was able to earn CN¥0.21 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don't share these attributes.

Zhejiang Dingli MachineryLtd's Earnings Growth And 21% ROE

To start with, Zhejiang Dingli MachineryLtd's ROE looks acceptable. Especially when compared to the industry average of 7.5% the company's ROE looks pretty impressive. This certainly adds some context to Zhejiang Dingli MachineryLtd's exceptional 23% net income growth seen over the past five years. We reckon that there could also 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.

We then compared Zhejiang Dingli MachineryLtd'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 11% in the same 5-year 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. Doing so will help them establish if the stock's future looks promising or ominous. 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 Zhejiang Dingli MachineryLtd is trading on a high P/E or a low P/E, relative to its industry.

Is Zhejiang Dingli MachineryLtd Efficiently Re-investing Its Profits?

Zhejiang Dingli MachineryLtd has a really low three-year median payout ratio of 18%, meaning that it has the remaining 82% left over to reinvest into its business. So it seems like the management is reinvesting profits heavily to grow its business and this reflects in its earnings growth number.

Additionally, Zhejiang Dingli MachineryLtd has paid dividends over a period of nine years which means that the company is pretty serious about sharing its profits with shareholders. Based on the latest analysts' estimates, we found that the company's future payout ratio over the next three years is expected to hold steady at 18%. As a result, Zhejiang Dingli MachineryLtd's ROE is not expected to change by much either, which we inferred from the analyst estimate of 20% for future ROE.

Conclusion

In total, we are pretty happy with Zhejiang Dingli MachineryLtd's performance. Particularly, we like that the company is reinvesting heavily into its business, and at a high rate of return. Unsurprisingly, this has led to an impressive earnings growth. That being so, a study of the latest analyst forecasts show that the company is expected to see a slowdown in its future earnings growth.
