How Is ROE Calculated?

ROE 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 China Southern Power Grid Energy Efficiency & Clean Energy is:

1.7% = CN¥131m ÷ CN¥7.7b (Based on the trailing twelve months to September 2024).

The 'return' is the amount earned after tax 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¥0.02 in profit.

Does China Southern Power Grid Energy Efficiency & Clean Energy Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, China Southern Power Grid Energy Efficiency & Clean Energy has a lower ROE than the average (5.5%) in the Commercial Services industry.

That certainly isn't ideal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved.

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

China Southern Power Grid Energy Efficiency & Clean Energy's Debt And Its 1.7% ROE

It's worth noting the high use of debt by China Southern Power Grid Energy Efficiency & Clean Energy, leading to its debt to equity ratio of 1.04. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

Summary

Return on equity is one way we can compare its business quality of different companies. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
