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 Shenzhen Zhongjin Lingnan Nonfemet Co. Ltd. (SZSE:000060), 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 other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Is ROE Calculated?

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 Shenzhen Zhongjin Lingnan Nonfemet is:

7.0% = CN¥1.2b ÷ CN¥17b (Based on the trailing twelve months to September 2023).

The 'return' is the income the business earned over the last year. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.07 in profit.

Does Shenzhen Zhongjin Lingnan Nonfemet 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. The image below shows that Shenzhen Zhongjin Lingnan Nonfemet has an ROE that is roughly in line with the Metals and Mining industry average (7.0%).

That isn't amazing, but it is respectable. While at least the ROE is not lower than the industry, its still worth checking what role the company's debt plays as high debt levels relative to equity may also make the ROE appear high. If a company takes on too much debt, it is at higher risk of defaulting on interest payments.

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 and second cases, the ROE will reflect this use of cash for investment in the business. 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.

Combining Shenzhen Zhongjin Lingnan Nonfemet's Debt And Its 7.0% Return On Equity

Shenzhen Zhongjin Lingnan Nonfemet does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.09. 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.

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. 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.
