How To 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 Optical Cable is:

8.4% = US$2.1m ÷ US$25m (Based on the trailing twelve months to October 2023).

The 'return' is the income the business earned over the last year. That means that for every $1 worth of shareholders' equity, the company generated $0.08 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. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. 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.

Optical Cable's Earnings Growth And 8.4% ROE

At first glance, Optical Cable's ROE doesn't look very promising. However, its ROE is similar to the industry average of 8.6%, so we won't completely dismiss the company. Looking at Optical Cable's exceptional 44% five-year net income growth in particular, we are definitely impressed. 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 Optical Cable'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 25% in the same 5-year period.

Earnings growth is an important metric to consider when valuing a stock. 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. Is Optical Cable fairly valued compared to other companies? These 3 valuation measures might help you decide.

Optical Cable 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.
