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).

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 short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Thomson Medical Group is:

9.6% = S$59m ÷ S$608m (Based on the trailing twelve months to June 2022).

The 'return' is the yearly profit. One way to conceptualize this is that for each SGD1 of shareholders' capital it has, the company made SGD0.10 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 (13%) in the Healthcare industry classification.

Unfortunately, that's sub-optimal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved.

The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow 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.

Thomson Medical Group's Debt And Its 9.6% ROE

It's worth noting the high use of debt by Thomson Medical Group, leading to its debt to equity ratio of 1.03. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
