With its stock down 11% over the past three months, it is easy to disregard Hengtong Optic-Electric (SHSE:600487). We, however decided to study the company's financials to determine if they have got anything to do with the price decline. Long-term fundamentals are usually what drive market outcomes, so it's worth paying close attention. Particularly, we will be paying attention to Hengtong Optic-Electric'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. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How Do You 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 Hengtong Optic-Electric is:

7.0% = CN¥1.9b ÷ CN¥27b (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?

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

Hengtong Optic-Electric's Earnings Growth And 7.0% ROE

When you first look at it, Hengtong Optic-Electric's ROE doesn't look that attractive. However, its ROE is similar to the industry average of 6.7%, so we won't completely dismiss the company. Having said that, Hengtong Optic-Electric's five year net income decline rate was 5.3%. Remember, the company's ROE is a bit low to begin with. Therefore, the decline in earnings could also be the result of this.

That being said, we compared Hengtong Optic-Electric's performance with the industry and were concerned when we found that while the company has shrunk its earnings, the industry has grown its earnings at a rate of 13% in the same 5-year period.

Earnings growth is a huge factor in stock valuation. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. Doing so will help them establish if the stock's future looks promising or ominous. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Hengtong Optic-Electric is trading on a high P/E or a low P/E, relative to its industry.

Is Hengtong Optic-Electric Efficiently Re-investing Its Profits?

Hengtong Optic-Electric's low three-year median payout ratio of 11% (or a retention ratio of 89%) over the last three years should mean that the company is retaining most of its earnings to fuel its growth but the company's earnings have actually shrunk. The low payout should mean that the company is retaining most of its earnings and consequently, should see some growth. So there might be other factors at play here which could potentially be hampering growth. For instance, the business has faced some headwinds.

In addition, Hengtong Optic-Electric 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. Upon studying the latest analysts' consensus data, we found that the company is expected to keep paying out approximately 12% of its profits over the next three years. Still, forecasts suggest that Hengtong Optic-Electric's future ROE will rise to 10% even though the the company's payout ratio is not expected to change by much.

Summary
