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 CML Microsystems plc (LON:CML).
CML Microsystems has a ROE of 10%, based on the last twelve months. One way to conceptualize this, is that for each £1 of shareholders' equity it has, the company made £0.10 in profit.
How Do You Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for CML Microsystems:
10% = UK£4.3m ÷ UK£43m (Based on the trailing twelve months to September 2018.)
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. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
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 yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.
Does CML Microsystems 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. You can see in the graphic below that CML Microsystems has an ROE that is fairly close to the average for the Semiconductor industry (11%).
That isn't amazing, but it is respectable. ROE doesn't tell us if the share price is low, but it can inform us to the nature of the business. For those looking for a bargain, other factors may be more important.

How Does Debt Impact Return On Equity?
Most companies need money -- from somewhere -- to grow their 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 debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining CML Microsystems's Debt And Its 10% Return On Equity
Shareholders will be pleased to learn that CML Microsystems has not one iota of net debt! Its respectable ROE suggests it is a business worth watching, but it's even better the company achieved this without leverage. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.
The Bottom Line On ROE
Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
