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 Hangzhou Cable Co., Ltd. (SHSE:603618), 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. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

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 Hangzhou Cable is:

5.2% = CN¥149m ÷ CN¥2.9b (Based on the trailing twelve months to March 2023).

The 'return' refers to a company's earnings over the last year. So, this means that for every CN¥1 of its shareholder's investments, the company generates a profit of CN¥0.05.

Does Hangzhou Cable 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. If you look at the image below, you can see Hangzhou Cable has a lower ROE than the average (7.8%) in the Electrical industry classification.

Unfortunately, that's sub-optimal. 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.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money 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 debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

Combining Hangzhou Cable's Debt And Its 5.2% Return On Equity

Hangzhou Cable does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.60. 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 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 when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
