Most readers would already be aware that Lens Technology's (SZSE:300433) stock increased significantly by 11% over the past month. As most would know, fundamentals are what usually guide market price movements over the long-term, so we decided to look at the company's key financial indicators today to determine if they have any role to play in the recent price movement. Particularly, we will be paying attention to Lens Technology'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?

Return on equity 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 Lens Technology is:

7.5% = CN¥3.4b ÷ CN¥45b (Based on the trailing twelve months to September 2023).

The 'return' is the profit 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¥0.07 in profit.

What Has ROE Got To Do With Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company's earnings growth potential. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

A Side By Side comparison of Lens Technology's Earnings Growth And 7.5% ROE

At first glance, Lens Technology's ROE doesn't look very promising. However, given that the company's ROE is similar to the average industry ROE of 6.6%, we may spare it some thought. Having said that, Lens Technology has shown a modest net income growth of 6.2% over the past five years. 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 Lens Technology's net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 9.9% in the same 5-year period, which is a bit concerning.

Earnings growth is a huge factor in stock valuation. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await.

Is Lens Technology Using Its Retained Earnings Effectively?

Lens Technology has a healthy combination of a moderate three-year median payout ratio of 30% (or a retention ratio of 70%) and a respectable amount of growth in earnings as we saw above, meaning that the company has been making efficient use of its profits.

Besides, Lens Technology has been paying dividends over a period of eight years. This shows that the company is committed to sharing profits with its shareholders. Our latest analyst data shows that the future payout ratio of the company over the next three years is expected to be approximately 33%. Therefore, the company's future ROE is also not expected to change by much with analysts predicting an ROE of 9.0%.

Conclusion

On the whole, we do feel that Lens Technology has some positive attributes. Namely, its respectable earnings growth, which it achieved due to it retaining most of its profits. However, given the low ROE, investors may not be benefitting from all that reinvestment after all. That being so, the latest analyst forecasts show that the company will continue to see an expansion in its earnings.
