Most readers would already be aware that Zhejiang Lante Optics' (SHSE:688127) stock increased significantly by 36% over the past three months. Given the company's impressive performance, we decided to study its financial indicators more closely as a company's financial health over the long-term usually dictates market outcomes. Particularly, we will be paying attention to Zhejiang Lante Optics' 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. 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?

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 Lante Optics is:

14% = CN¥250m ÷ CN¥1.7b (Based on the trailing twelve months to September 2024).

The 'return' is the profit over the last twelve months. So, this means that for every CN¥1 of its shareholder's investments, the company generates a profit of CN¥0.14.

What Has ROE Got To Do With Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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.

Zhejiang Lante Optics' Earnings Growth And 14% ROE

To start with, Zhejiang Lante Optics' ROE looks acceptable. Especially when compared to the industry average of 6.3% the company's ROE looks pretty impressive. Despite this, Zhejiang Lante Optics' five year net income growth was quite low averaging at only 3.8%. This is generally not the case as when a company has a high rate of return it should usually also have a high earnings growth rate. A few likely reasons why this could happen is that the company could have a high payout ratio or the business has allocated capital poorly, for instance.

As a next step, we compared Zhejiang Lante Optics' 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 3.9% 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. 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 Lante Optics is trading on a high P/E or a low P/E, relative to its industry.

Is Zhejiang Lante Optics Making Efficient Use Of Its Profits?

While the company did pay out a portion of its dividend in the past, it currently doesn't pay a regular dividend. We infer that the company has been reinvesting all of its profits to grow its business.

Conclusion

On the whole, we feel that Zhejiang Lante Optics' performance has been quite good. Specifically, we like that the company is reinvesting a huge chunk of its profits at a high rate of return.
