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 Guangdong Shunna Electric is:

10% = CN¥94m ÷ CN¥905m (Based on the trailing twelve months to September 2023).

The 'return' is the yearly profit. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.10 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.

Guangdong Shunna Electric's Earnings Growth And 10% ROE

When you first look at it, Guangdong Shunna Electric's ROE doesn't look that attractive. However, the fact that the company's ROE is higher than the average industry ROE of 7.2%, is definitely interesting. Particularly, the substantial 75% net income growth seen by Guangdong Shunna Electric over the past five years is impressive . Bear in mind, the company does have a moderately low ROE. It is just that the industry ROE is lower. Therefore, the growth in earnings could also be the result of other factors. For example, it is possible that the broader industry is going through a high growth phase, or that the company has a low payout ratio.

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 14%.

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 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 dividend to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Summary

In total, we are pretty happy with Guangdong Shunna Electric's performance. In particular, it's great to see that the company has seen significant growth in its earnings backed by a respectable ROE and a high reinvestment rate.
