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 Zhaojin Mining Industry Company Limited (HKG:1818), by way of a worked example.

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. 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?

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 Zhaojin Mining Industry is:

3.4% = CN¥716m ÷ CN¥21b (Based on the trailing twelve months to June 2023).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each HK\$1 of shareholders' capital it has, the company made HK\$0.03 in profit.

## Does Zhaojin Mining Industry Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see Zhaojin Mining Industry has a lower ROE than the average (8.6%) in the Metals and Mining industry classification.

That's not what we like to see. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

## The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow 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 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 Zhaojin Mining Industry's Debt And Its 3.4% Return On Equity

Zhaojin Mining Industry clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.06. 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 useful for comparing the quality of different businesses. 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.

But when a business is high quality, the market often bids it up to a price that reflects this. 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.
