Most readers would already be aware that Joy Kie's (SZSE:300994) stock increased significantly by 16% over the past week. Given that stock prices are usually aligned with a company's financial performance in the long-term, we decided to study its financial indicators more closely to see if they had a hand to play in the recent price move. Particularly, we will be paying attention to Joy Kie's ROE today.

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. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How To Calculate Return On Equity?

The formula for ROE is:

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

So, based on the above formula, the ROE for Joy Kie is:

9.2% = CN¥107m ÷ CN¥1.2b (Based on the trailing twelve months to September 2023).

The 'return' is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.09 in profit.

Why Is ROE Important For Earnings Growth?

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

Joy Kie's Earnings Growth And 9.2% ROE

When you first look at it, Joy Kie's ROE doesn't look that attractive. However, the fact that the company's ROE is higher than the average industry ROE of 6.9%, is definitely interesting. Consequently, this likely laid the ground for the decent growth of 9.3% seen over the past five years by Joy Kie. Bear in mind, the company does have a moderately low ROE. It is just that the industry ROE is lower. So there might well be other reasons for the earnings to grow. 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 Joy Kie's 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 9.0% in the same period.

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. This then helps them determine if the stock is placed for a bright or bleak future.

Is Joy Kie Using Its Retained Earnings Effectively?

While Joy Kie has a three-year median payout ratio of 67% (which means it retains 33% of profits), the company has still seen a fair bit of earnings growth in the past, meaning that its high payout ratio hasn't hampered its ability to grow.

Additionally, Joy Kie has paid dividends over a period of three years which means that the company is pretty serious about sharing its profits with shareholders.
