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. To keep the lesson grounded in practicality, we'll use ROE to better understand Ginlong Technologies Co., Ltd. (SZSE:300763).

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. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Is ROE Calculated?

The formula for ROE is:

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

So, based on the above formula, the ROE for Ginlong Technologies is:

8.4% = CN¥697m ÷ CN¥8.3b (Based on the trailing twelve months to September 2024).

The 'return' is the yearly profit. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.08 in profit.

Does Ginlong Technologies Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Ginlong Technologies has a better ROE than the average (6.4%) in the Electrical industry.

That's what we like to see. Bear in mind, a high ROE doesn't always mean superior financial performance. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

How Does Debt Impact Return On Equity?

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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Ginlong Technologies' Debt And Its 8.4% ROE

Ginlong Technologies clearly uses a high amount of debt to boost returns, as it has a 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. 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. In our books, the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
