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 RHI Magnesita N.V. (LON:RHIM), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. 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 RHI Magnesita is:

10% = €146m ÷ €1.5b (Based on the trailing twelve months to June 2023).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every £1 worth of equity, the company was able to earn £0.10 in profit.

Does RHI Magnesita 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. The image below shows that RHI Magnesita has an ROE that is roughly in line with the Basic Materials industry average (11%). roe

That isn't amazing, but it is respectable. While at least the ROE is not lower than the industry, its still worth checking what role the company's debt plays as high debt levels relative to equity may also make the ROE appear high. If a company takes on too much debt, it is at higher risk of defaulting on interest payments.  Our risks dashboardshould have the 3 risks we have identified for RHI Magnesita.

The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.



RHI Magnesita's Debt And Its 10% ROE

It's worth noting the high use of debt by RHI Magnesita, leading to its debt to equity ratio of 1.25. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

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. 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.

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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this freereport on analyst forecasts for the company.

But note: RHI Magnesita may not be the best stock to buy. So take a peek at this free list of interesting companies with high ROE and low debt.
