Guangdong Shunna Electric (SZSE:000533) has had a great run on the share market with its stock up by a significant 45% over the last 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. Specifically, we decided to study Guangdong Shunna Electric'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. Put another way, it reveals the company's success at turning shareholder investments into profits.

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 Guangdong Shunna Electric is:

12% = CN¥120m ÷ CN¥1.0b (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¥0.12.

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. 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.

Guangdong Shunna Electric's Earnings Growth And 12% ROE

To start with, Guangdong Shunna Electric's ROE looks acceptable. On comparing with the average industry ROE of 6.4% the company's ROE looks pretty remarkable. This certainly adds some context to Guangdong Shunna Electric's exceptional 67% net income growth seen over the past five years. We believe that there might also be other aspects that are positively influencing the company's earnings growth. For instance, the company has a low payout ratio or is being managed efficiently.

As a next step, we compared Guangdong Shunna Electric's net income growth with the industry, and pleasingly, we found that the growth seen by the company is higher than the average industry growth of 10%.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. 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 Guangdong Shunna Electric is trading on a high P/E or a low P/E, relative to its industry.

Is Guangdong Shunna Electric Efficiently Re-investing Its Profits?

Guangdong Shunna Electric doesn't pay any regular dividends currently which essentially means that it has been reinvesting all of its profits into the business. This definitely contributes to the high earnings growth number that we discussed above.

Summary

On the whole, we feel that Guangdong Shunna Electric's 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. This of course has caused the company to see substantial growth in its earnings.
