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 Caesarstone Ltd. (NASDAQ:CSTE), by way of a worked example.
Our data shows Caesarstone has a return on equity of 3.8% for the last year. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.04.
How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Caesarstone:
3.8% = US$18m ÷ US$475m (Based on the trailing twelve months to June 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does ROE Mean?
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 yearly profit. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Caesarstone Have A Good Return On Equity?
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 is clear from the image below, Caesarstone has a lower ROE than the average (13%) in the Building industry.
Unfortunately, that's sub-optimal. 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. Still, shareholders might want to check if insiders have been selling.
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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Combining Caesarstone's Debt And Its 3.8% Return On Equity
While Caesarstone does have a tiny amount of debt, with debt to equity of just 0.0018, we think the use of debt is very modest. Its ROE is certainly on the low side, and since it already uses debt, we're not too excited about the company. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.
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 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 you might want to take a peek at this data-rich interactive graph of forecasts for the company.
