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). To keep the lesson grounded in practicality, we'll use ROE to better understand Thomson Medical Group Limited (SGX:A50).

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

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 Thomson Medical Group is:

7.1% = S$41m ÷ S$575m (Based on the trailing twelve months to June 2023).

The 'return' is the amount earned after tax over the last twelve months. That means that for every SGD1 worth of shareholders' equity, the company generated SGD0.07 in profit.

Does Thomson Medical Group 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, Thomson Medical Group has a lower ROE than the average (11%) in the Healthcare industry classification.

That's not what we like to see. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

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 first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.

Combining Thomson Medical Group's Debt And Its 7.1% Return On Equity

It's worth noting the high use of debt by Thomson Medical Group, leading to its debt to equity ratio of 1.30. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
