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 Ansaldo STS SpA (BIT:STS), by way of a worked example.
Ansaldo STS has a ROE of 8.5%, based on the last twelve months. One way to conceptualize this, is that for each €1 of shareholders’ equity it has, the company made €0.085 in profit.
How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Ansaldo STS:
8.5% = €63m ÷ €747m (Based on the trailing twelve months to June 2018.)
It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. 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 Return On Equity 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 profit over the last twelve months. A higher profit will lead to a a higher ROE. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does Ansaldo STS 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 shown in the graphic below, Ansaldo STS has a lower ROE than the average (12%) in the infrastructure industry classification.
Unfortunately, that’s sub-optimal. It is better when the ROE is above industry average, but a low one doesn’t necessarily mean the business is overpriced. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
How Does Debt Impact ROE?
Virtually all companies need money to invest in the business, to grow 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Ansaldo STS’s Debt And Its 8.5% ROE
Although Ansaldo STS does use a little debt, its debt to equity ratio of just 0.0022 is very low. Although the ROE isn’t overly impressive, the debt load is modest, suggesting the business has potential. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.
The Key Takeaway
Return on equity is useful for comparing the quality of different businesses. 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. 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.
