While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we’ll use ROE to better understand NeuroMetrix, Inc. (NASDAQ:NURO).
Our data shows NeuroMetrix has a return on equity of 0.4% for the last year. One way to conceptualize this, is that for each $1 of shareholders’ equity it has, the company made $0.0039 in profit.
How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for NeuroMetrix:
0.4% = 0.023605 ÷ US$6.1m (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 earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.
What Does ROE Mean?
ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. 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 NeuroMetrix Have A Good ROE?
Arguably the easiest way to assess company’s ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, NeuroMetrix has a lower ROE than the average (9.7%) in the Medical Equipment industry.
That’s not what we like to see. 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.
Why You Should Consider Debt When Looking At ROE
Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. 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 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 NeuroMetrix’s Debt And Its 0.4% Return On Equity
NeuroMetrix is free of net debt, which is a positive for shareholders. So while I find its ROE to be rather low, at least it didn’t use 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 a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth — and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
