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. To keep the lesson grounded in practicality, we’ll use ROE to better understand Century Aluminum Company (NASDAQ:CENX).
Our data shows Century Aluminum has a return on equity of 4.1% 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 $0.041.
How Do I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Century Aluminum:
4.1% = 31.714 ÷ US$834m (Based on the trailing twelve months to September 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 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 yearly profit. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.
Does Century Aluminum 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 is clear from the image below, Century Aluminum has a lower ROE than the average (13%) in the Metals and Mining industry.
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 might be wise to check if insiders have been selling.
How Does Debt Impact Return On Equity?
Most companies need money — from somewhere — to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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 Century Aluminum’s Debt And Its 4.1% Return On Equity
While Century Aluminum does have some debt, with debt to equity of just 0.32, we wouldn’t say debt is excessive. Its ROE is quite low, and the company already has some debt, so surely shareholders are hoping for an improvement. 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 Bottom Line On ROE
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.
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.
