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 Abiomed, Inc. (NASDAQ:ABMD), by way of a worked example.
Abiomed has a ROE of 23%, based on the last twelve months. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.23.
How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for Abiomed:
23% = US$245m ÷ US$1.0b (Based on the trailing twelve months to December 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 Return On Equity Mean?
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. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.
Does Abiomed Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Abiomed has a superior ROE than the average (11%) company in the Medical Equipment industry.
That's what I like to see. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought 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 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.
Abiomed's Debt And Its 23% ROE
Shareholders will be pleased to learn that Abiomed has not one iota of net debt! Its high ROE already points to a high quality business, but the lack of debt is a cherry on top. 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. 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. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
