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 Sembcorp Industries Ltd (SGX:U96), 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 other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Sembcorp Industries is:
19% = S$1.0b ÷ S$5.5b (Based on the trailing twelve months to June 2025).
The 'return' is the yearly profit. That means that for every SGD1 worth of shareholders' equity, the company generated SGD0.19 in profit.

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, Sembcorp Industries has a better ROE than the average (7.6%) in the Integrated Utilities industry.
That's what we like to see. Bear in mind, a high ROE doesn't always mean superior financial performance. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk . Our risks dashboardshould have the 2 risks we have identified for Sembcorp Industries.
Most companies need money -- from somewhere -- 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 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.
It's worth noting the high use of debt by Sembcorp Industries, leading to its debt to equity ratio of 1.50. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
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. All else being equal, a higher ROE is better.
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.
