Zhengzhou Coal Industry & Electric Power (SHSE:600121) has had a great run on the share market with its stock up by a significant 42% over the last three months. 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. Specifically, we decided to study Zhengzhou Coal Industry & Electric Power's ROE in this article.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

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 Zhengzhou Coal Industry & Electric Power is:

9.5% = CN¥281m ÷ CN¥2.9b (Based on the trailing twelve months to September 2024).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.10 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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. 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.

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. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await. 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 Zhengzhou Coal Industry & Electric Power is trading on a high P/E or a low P/E, relative to its industry.
