Is Sunny Optical Technology (Group) Company Limited's (HKG:2382) Recent Stock Performance Influenced By Its Fundamentals In Any Way?

Most readers would already be aware that Sunny Optical Technology (Group)'s (HKG:2382) stock increased significantly by 24% over the past three months. 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 Sunny Optical Technology (Group)'s ROE today.

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

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 Sunny Optical Technology (Group) is:

13% = CN¥3.4b ÷ CN¥27b (Based on the trailing twelve months to June 2025).

The 'return' is the amount earned after tax over the last twelve months. That means that for every HK$1 worth of shareholders' equity, the company generated HK$0.13 in profit.

What Has ROE Got To Do With Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. 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.

Sunny Optical Technology (Group)'s Earnings Growth And 13% ROE

To begin with, Sunny Optical Technology (Group) seems to have a respectable ROE. Especially when compared to the industry average of 8.4% the company's ROE looks pretty impressive. For this reason, Sunny Optical Technology (Group)'s five year net income decline of 22% raises the question as to why the high ROE didn't translate into earnings growth. Therefore, there might be some other aspects that could explain this. These include low earnings retention or poor allocation of capital.

Next, when we compared with the industry, which has shrunk its earnings at a rate of 2.0% in the same 5-year period, we still found Sunny Optical Technology (Group)'s performance to be quite bleak, because the company has been shrinking its earnings faster than the industry.

Is Sunny Optical Technology (Group) Efficiently Re-investing Its Profits?

When we piece together Sunny Optical Technology (Group)'s low three-year median payout ratio of 20% (where it is retaining 80% of its profits), calculated for the last three-year period, we are puzzled by the lack of growth. This typically shouldn't be the case when a company is retaining most of its earnings. So there could be some other explanations in that regard. For example, the company's business may be deteriorating.

In addition, Sunny Optical Technology (Group) has been paying dividends over a period of at least ten years suggesting that keeping up dividend payments is way more important to the management even if it comes at the cost of business growth. Based on the latest analysts' estimates, we found that the company's future payout ratio over the next three years is expected to hold steady at 19%. As a result, Sunny Optical Technology (Group)'s ROE is not expected to change by much either, which we inferred from the analyst estimate of 15% for future ROE.

Conclusion

On the whole, we do feel that Sunny Optical Technology (Group) has some positive attributes. However, given the high ROE and high profit retention, we would expect the company to be delivering strong earnings growth, but that isn't the case here. This suggests that there might be some external threat to the business, that's hampering its growth. That being so, the latest industry analyst forecasts show that the analysts are expecting to see a huge improvement in the company's earnings growth rate.
