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 Bodycote plc (LON:BOY).

Over the last twelve months Bodycote has recorded a ROE of 15%. That means that for every £1 worth of shareholders’ equity, it generated £0.15 in profit.

How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Bodycote:

15% = UK£104m ÷ UK£680m (Based on the trailing twelve months to June 2018.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders’ equity is a little more complicated. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.

What Does Return On Equity Signify?

Return on Equity measures a company’s profitability against the profit it has kept for the business (plus any capital injections). The ‘return’ is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.

Does Bodycote 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As you can see in the graphic below, Bodycote has a higher ROE than the average (13%) in the machinery industry.

That’s clearly a positive. In my book, a high ROE almost always warrants a closer look. For example, I often check if insiders have been buying shares .

How Does Debt Impact ROE?

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