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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Clean Harbors, Inc. (NYSE:CLH).
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Put another way, it reveals the company's success at turning shareholder investments into profits.
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Clean Harbors is:
16% = US$417m ÷ US$2.5b (Based on the trailing twelve months to September 2024).
The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.16 in profit.
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Clean Harbors has a higher ROE than the average (11%) in the Commercial Services industry.
That's clearly a positive. However, bear in mind that a high ROE doesn't necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk. Our risks dashboardshould have the 2 risks we have identified for Clean Harbors.
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 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Clean Harbors clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.10. While its ROE is respectable, it is worth keeping in mind that there is usually a limit as to how much debt a company can use. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
