# Is Select Medical Holdings Corporation’s (NYSE:SEM) ROE Of 15% Impressive?

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 Select Medical Holdings Corporation (NYSE:SEM).

Our data shows Select Medical Holdings has a return on equity of 15% for the last year. Another way to think of that is that for every \$1 worth of equity in the company, it was able to earn \$0.15.

### How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Select Medical Holdings:

15% = US\$193m ÷ US\$1.6b (Based on the trailing twelve months to June 2018.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.

### What Does ROE Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

### Does Select Medical Holdings Have A Good Return On Equity?

By comparing a company’s ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. You can see in the graphic below that Select Medical Holdings has an ROE that is fairly close to the average for the healthcare industry (15%).

That isn’t amazing, but it is respectable. ROE can change from year to year, based on decisions that have been made in the past. So I like to check the tenure of the board and CEO, before reaching any conclusions.

### How Does Debt Impact ROE?

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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt used for growth will improve returns, but won’t affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

### Combining Select Medical Holdings’s Debt And Its 15% Return On Equity

Select Medical Holdings does use a significant amount of debt to increase returns. It has a debt to equity ratio of 2.11. There’s no doubt the ROE is respectable, but it’s worth keeping in mind that metric is elevated by the use of debt. Debt does bring some extra risk, so it’s only really worthwhile when a company generates some decent returns from it.

### The Bottom Line On ROE

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.

But when a business is high quality, the market often bids it up to a price that reflects this. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
