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 Wireless Telecom Group, Inc. (NYSEMKT:WTT), by way of a worked example.
Over the last twelve months Wireless Telecom Group has recorded a ROE of 0.1%. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.0011 in profit.
How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Wireless Telecom Group:
0.1% = US$35k ÷ US$32m (Based on the trailing twelve months to December 2018.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all the money paid into the company from shareholders, plus any earnings retained. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE Signify?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.
Does Wireless Telecom Group 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. If you look at the image below, you can see Wireless Telecom Group has a lower ROE than the average (12%) in the Electronic 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 might be wise to check if insiders have been selling.
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 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Wireless Telecom Group's Debt And Its 0.1% Return On Equity
While Wireless Telecom Group does have a tiny amount of debt, with debt to equity of just 0.063, we think the use of debt is very modest. Its ROE is rather low, and it does use some debt, albeit not much. That's not great to see. 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 around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
