One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Chongqing Shunbo Aluminum Co.,Ltd. (SZSE:002996).

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 simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How To Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Chongqing Shunbo AluminumLtd is:

3.8% = CN¥124m ÷ CN¥3.3b (Based on the trailing twelve months to June 2024).

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¥0.04 in profit.

Does Chongqing Shunbo AluminumLtd 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. 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 Chongqing Shunbo AluminumLtd has a lower ROE than the average (7.5%) in the Metals and Mining industry classification.

That certainly isn't ideal. 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. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining Chongqing Shunbo AluminumLtd's Debt And Its 3.8% Return On Equity

Chongqing Shunbo AluminumLtd does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.79. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. 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. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
