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 Guangdong No.2 Hydropower Engineering Company is:

8.6% = CN¥369m ÷ CN¥4.3b (Based on the trailing twelve months to September 2022).

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¥0.09 in profit.

Does Guangdong No.2 Hydropower Engineering Company 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. You can see in the graphic below that Guangdong No.2 Hydropower Engineering Company has an ROE that is fairly close to the average for the Construction industry (7.8%).

That isn't amazing, but it is respectable. 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. If so, this increases its exposure to financial risk. Our risks dashboardshould have the 2 risks we have identified for Guangdong No.2 Hydropower Engineering Company.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money 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 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.

Guangdong No.2 Hydropower Engineering Company's Debt And Its 8.6% ROE

It appears that Guangdong No.2 Hydropower Engineering Company makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 4.35. The combination of a rather low ROE and high debt to equity is a negative, in our book.

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 around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
