How To Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

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. 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 China Tower's Earnings Growth And 5.5% ROE

When you first look at it, China Tower's ROE doesn't look that attractive. However, its ROE is similar to the industry average of 5.8%, so we won't completely dismiss the company. Even so, China Tower has shown a fairly decent growth in its net income which grew at a rate of 14%. Taking into consideration that the ROE is not particularly high, we reckon that there could also be other factors at play which could be influencing the company's growth. For instance, the company has a low payout ratio or is being managed efficiently.

We then compared China Tower'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 1.6% in the same 5-year period.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. This then helps them determine if the stock is placed for a bright or bleak future.
