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 Chang Wah Electromaterials is:

17% = NT$1.3b ÷ NT$8.1b (Based on the trailing twelve months to September 2020).

The 'return' is the amount earned after tax over the last twelve months. So, this means that for every NT$1 of its shareholder's investments, the company generates a profit of NT$0.17.

Does Chang Wah Electromaterials 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. 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, Chang Wah Electromaterials has a better ROE than the average (9.9%) in the Electronic industry.

That's clearly a positive. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

The Importance Of Debt To Return On Equity

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

Combining Chang Wah Electromaterials' Debt And Its 17% Return On Equity

It's worth noting the high use of debt by Chang Wah Electromaterials, leading to its debt to equity ratio of 1.24. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. 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 useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock.
