Most readers would already be aware that Shanghai Sinotec's (SHSE:603121) stock increased significantly by 16% over the past week. But the company's key financial indicators appear to be differing across the board and that makes us question whether or not the company's current share price momentum can be maintained. Particularly, we will be paying attention to Shanghai Sinotec'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. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

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 Shanghai Sinotec is:

7.2% = CN¥95m ÷ CN¥1.3b (Based on the trailing twelve months to June 2024).

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 Is The Relationship Between ROE And 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. 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.

Shanghai Sinotec's Earnings Growth And 7.2% ROE

At first glance, Shanghai Sinotec's ROE doesn't look very promising. However, its ROE is similar to the industry average of 8.5%, so we won't completely dismiss the company. But Shanghai Sinotec saw a five year net income decline of 3.1% over the past five years. Remember, the company's ROE is a bit low to begin with. Therefore, the decline in earnings could also be the result of this.

However, when we compared Shanghai Sinotec's growth with the industry we found that while the company's earnings have been shrinking, the industry has seen an earnings growth of 9.9% in the same period. This is quite worrisome.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. 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 Shanghai Sinotec Using Its Retained Earnings Effectively?

While the company did payout a portion of its dividend in the past, it currently doesn't pay a regular dividend. This implies that potentially all of its profits are being reinvested in the business.

Summary

Overall, we have mixed feelings about Shanghai Sinotec. While the company does have a high rate of reinvestment, the low ROE means that all that reinvestment is not reaping any benefit to its investors, and moreover, its having a negative impact on the earnings growth. Until now, we have only just grazed the surface of the company's past performance by looking at the company's fundamentals.
