One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We'll use ROE to examine Commvault Systems, Inc. (NASDAQ:CVLT), by way of a worked example.
Commvault Systems has a ROE of 1.5%, based on the last twelve months. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.015 in profit.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Commvault Systems:
1.5% = US$5.3m ÷ US$360m (Based on the trailing twelve months to June 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. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.
What Does ROE Signify?
Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). 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. That means it can be interesting to compare the ROE of different companies.
Does Commvault Systems 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, Commvault Systems has a lower ROE than the average (9.2%) in the Software industry classification.
That's not what we like to see. We prefer it when the ROE of a company is above the industry average, but it's not the be-all and end-all if it is lower. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
Why You Should Consider Debt When Looking At ROE
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 use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Commvault Systems's Debt And Its 1.5% ROE
Shareholders will be pleased to learn that Commvault Systems has not one iota of net debt! So while I find its ROE to be rather low, at least it didn't use debt. After all, when a company has a strong balance sheet, it can often find ways to invest in growth, even if it takes some time.
But It's Just One Metric
Return on equity is useful for comparing the quality of different businesses. In my book the highest quality companies have high return on equity, despite low debt. 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.
