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). By way of learning-by-doing, we'll look at ROE to gain a better understanding of Napier Port Holdings Limited (NZSE:NPH).
Napier Port Holdings has a ROE of 2.0%, based on the last twelve months. That means that for every NZ$1 worth of shareholders' equity, it generated NZ$0.02 in profit.
How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for Napier Port Holdings:
2.0% = NZ$6.8m ÷ NZ$335m (Based on the trailing twelve months to September 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. 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 ROE Signify?
ROE looks at the amount a company earns relative to the money it has kept within the business. 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. That means it can be interesting to compare the ROE of different companies.
Does Napier Port 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Napier Port Holdings has a lower ROE than the average (8.6%) in the Infrastructure industry.
Unfortunately, that's sub-optimal. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
The Importance Of Debt To Return On Equity
Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Napier Port Holdings's Debt And Its 2.0% ROE
One positive for shareholders is that Napier Port Holdings does not have any net debt! Without a doubt it has a fairly low ROE, but that isn't so bad when you consider it has no debt. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.
But It's Just One Metric
Return on equity is one way we can compare the business quality of different companies. 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.
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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
