While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Estun Automation Co., Ltd (SZSE:002747), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You Calculate Return On Equity?

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 Estun Automation is:

3.5% = CN¥97m ÷ CN¥2.8b (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¥0.03 in profit.

Does Estun Automation Have A Good ROE?

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 shown in the graphic below, Estun Automation has a lower ROE than the average (6.9%) in the Machinery industry classification.

That's not what we like to see. 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. Our risks dashboard should have the 3 risks we have identified for Estun Automation.

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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 Estun Automation's Debt And Its 3.5% Return On Equity

Estun Automation clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.40. 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 a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too. So I think it may be worth checking this free report on analyst forecasts for the company.
