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). We'll use ROE to examine BW Offshore Limited (OB:BWO), by way of a worked example.
Our data shows BW Offshore has a return on equity of 4.1% for the last year. One way to conceptualize this, is that for each NOK1 of shareholders' equity it has, the company made NOK0.041 in profit.
How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for BW Offshore:
4.1% = US$44m ÷ US$1.4b (Based on the trailing twelve months to March 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does ROE Signify?
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. That means ROE can be used to compare two businesses.
Does BW Offshore 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. If you look at the image below, you can see BW Offshore has a lower ROE than the average (6.2%) in the Energy Services industry classification.
That certainly isn't ideal. We'd prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
How Does Debt Impact ROE?
Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.
Combining BW Offshore's Debt And Its 4.1% Return On Equity
Although BW Offshore does use debt, its debt to equity ratio of 0.98 is still low. Its ROE isn't particularly impressive, but the debt levels are quite modest, so the business probably has some real potential. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
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. 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.
