How To Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Guangdong No.2 Hydropower Engineering Company is:

3.1% = CN¥415m ÷ CN¥13b (Based on the trailing twelve months to September 2023).

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¥0.03 in profit.

Does Guangdong No.2 Hydropower Engineering Company 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Guangdong No.2 Hydropower Engineering Company has a lower ROE than the average (7.6%) in the Construction industry.

Unfortunately, that's sub-optimal. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.

Combining Guangdong No.2 Hydropower Engineering Company's Debt And Its 3.1% Return On Equity

It's worth noting the high use of debt by Guangdong No.2 Hydropower Engineering Company, leading to its debt to equity ratio of 2.31. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

Conclusion

Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
