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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Ningbo Joyson Electronic Corp. (SHSE:600699).

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Do You Calculate Return On Equity?

Return on equity 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 Ningbo Joyson Electronic is:

5.9% = CN¥1.1b ÷ CN¥19b (Based on the trailing twelve months to September 2023).

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¥0.06 in profit.

Does Ningbo Joyson Electronic Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, Ningbo Joyson Electronic has a lower ROE than the average (7.4%) in the Auto Components industry classification.

That certainly isn't ideal. 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. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved.

The Importance Of Debt To Return On Equity

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Ningbo Joyson Electronic's Debt And Its 5.9% ROE

Ningbo Joyson Electronic does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.04. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Conclusion

Return on equity is one way we can compare its business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
