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 Kaizhong Precision Technology Co., Ltd. (SZSE:002823), 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 short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How To Calculate Return On Equity?

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 Kaizhong Precision Technology is:

2.5% = CN¥36m ÷ CN¥1.4b (Based on the trailing twelve months to September 2023).

The 'return' is the amount earned after tax over the last twelve months. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.03 in profit.

Does Shenzhen Kaizhong Precision Technology Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, Shenzhen Kaizhong Precision Technology has a lower ROE than the average (7.1%) in the Electrical industry.

That's not what we like to see. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. 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 Return On Equity?

Companies usually need to invest money 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Shenzhen Kaizhong Precision Technology's Debt And Its 2.5% ROE

Shenzhen Kaizhong Precision Technology does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.18. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. 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.

Summary

Return on equity is one way we can compare its business quality of different companies. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
