Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Guangxi Guiguan Electric PowerCo.,Ltd. (SHSE:600236), by way of a worked example.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

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 Guangxi Guiguan Electric PowerCo.Ltd is:

7.2% = CN¥1.5b ÷ CN¥22b (Based on the trailing twelve months to March 2024).

The 'return' is the profit over the last twelve months. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.07 in profit.

Does Guangxi Guiguan Electric PowerCo.Ltd Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. You can see in the graphic below that Guangxi Guiguan Electric PowerCo.Ltd has an ROE that is fairly close to the average for the Renewable Energy industry (7.7%).

So while the ROE is not exceptional, at least its acceptable. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels.

How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Guangxi Guiguan Electric PowerCo.Ltd's Debt And Its 7.2% Return On Equity

Guangxi Guiguan Electric PowerCo.Ltd does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.08. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. 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. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
