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). By way of learning-by-doing, we'll look at ROE to gain a better understanding of Shanghai Zhenhua Heavy Industries Co., Ltd. (SHSE:600320).

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

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 Shanghai Zhenhua Heavy Industries is:

3.6% = CN¥691m ÷ CN¥19b (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¥0.04 in profit.

Does Shanghai Zhenhua Heavy Industries Have A Good ROE?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, Shanghai Zhenhua Heavy Industries has a lower ROE than the average (7.0%) in the Machinery industry classification.

That certainly isn't ideal. 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. Our risks dashboard should have the 3 risks we have identified for Shanghai Zhenhua Heavy Industries.

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- 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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

Shanghai Zhenhua Heavy Industries' Debt And Its 3.6% ROE

It's worth noting the high use of debt by Shanghai Zhenhua Heavy Industries, leading to its debt to equity ratio of 1.47. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from 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.

But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
