One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We’ll use ROE to examine Zoetis Inc. (NYSE:ZTS), by way of a worked example.

Zoetis has a ROE of 60%, based on the last twelve months. That means that for every $1 worth of shareholders’ equity, it generated $0.60 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 Zoetis:

60% = US$1.4b ÷ US$2.3b (Based on the trailing twelve months to March 2019.)

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 earnings retained by the company, plus any capital paid in by shareholders. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

What Does ROE Mean?

ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

Does Zoetis 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. As is clear from the image below, Zoetis has a better ROE than the average (19%) in the Pharmaceuticals industry.

That’s what I like to see. 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 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 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.

Combining Zoetis’s Debt And Its 60% Return On Equity

It’s worth noting the significant use of debt by Zoetis, leading to its debt to equity ratio of 2.78. While the ROE is impressive, that metric has clearly benefited from the company’s use of debt. Debt does bring extra risk, so it’s only really worthwhile when a company generates some decent returns from it.

In 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 the same ROE, then I would generally prefer the one with less debt.

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 free report on analyst forecasts for the company.
