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. To keep the lesson grounded in practicality, we'll use ROE to better understand Pharmanutra S.p.A. (BIT:PHN).
Over the last twelve months Pharmanutra has recorded a ROE of 35%. That means that for every €1 worth of shareholders' equity, it generated €0.35 in profit.
How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Pharmanutra:
35% = €8.6m ÷ €24m (Based on the trailing twelve months to December 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 Mean?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. 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 Pharmanutra Have A Good ROE?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Pharmanutra has a better ROE than the average (13%) in the Personal Products industry.
That is a good sign. I usually take a closer look when a company has a better ROE than industry peers. One data point to check is if insiders have bought shares recently.
Why You Should Consider Debt When Looking At 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 Pharmanutra's Debt And Its 35% Return On Equity
Although Pharmanutra does use debt, its debt to equity ratio of 0.22 is still low. The combination of modest debt and a very impressive ROE does suggest that the business is high quality. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.
Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. 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.
But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
