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 Zhe Jiang Hai Liang Co., Ltd (SZSE:002203), 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. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How To Calculate Return On Equity?

Return on equity 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 Zhe Jiang Hai Liang is:

6.5% = CN¥1.1b ÷ CN¥17b (Based on the trailing twelve months to March 2024).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every CN¥1 worth of equity, the company was able to earn CN¥0.07 in profit.

Does Zhe Jiang Hai Liang 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. The image below shows that Zhe Jiang Hai Liang has an ROE that is roughly in line with the Metals and Mining industry average (7.4%).

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. If a company takes on too much debt, it is at higher risk of defaulting on interest payments. Our risks dashboardshould have the 2 risks we have identified for Zhe Jiang Hai Liang.

The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Zhe Jiang Hai Liang's Debt And Its 6.5% ROE

It's worth noting the high use of debt by Zhe Jiang Hai Liang, leading to its debt to equity ratio of 1.23. 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. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
