How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Illinois Tool Works:
78% = US$2.5b ÷ US$3.2b (Based on the trailing twelve months to March 2019.)
Most know that net profit is the total earnings after all expenses, but the concept of shareholders’ equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. 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 looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.
Does Illinois Tool Works 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, Illinois Tool Works has a superior ROE than the average (14%) company in the Machinery industry.
That’s clearly a positive. In my book, a high ROE almost always warrants a closer look. One data point to check is if insiders have bought shares recently.
Why You Should Consider Debt When Looking At 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 and second cases, the ROE will reflect this use of cash for investment in the business. 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 Illinois Tool Works’s Debt And Its 78% Return On Equity
Illinois Tool Works clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 2.48. There’s no doubt its ROE is impressive, but the company appears to use its debt to boost that metric. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
In Summary
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. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
