Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Ningbo Joyson Electronic Corp. (SHSE:600699), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

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 Ningbo Joyson Electronic is:

7.2% = CN¥1.4b ÷ CN¥20b (Based on the trailing twelve months to March 2024).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.07 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. If you look at the image below, you can see Ningbo Joyson Electronic has a similar ROE to the average in the Auto Components industry classification (8.1%).

That's neither particularly good, nor bad. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels. If true, then it is more an indication of risk than the potential.

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. 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. 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 7.2% ROE

It's worth noting the high use of debt by Ningbo Joyson Electronic, leading to its debt to equity ratio of 1.07. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Summary

Return on equity is one way we can compare its business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

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.
