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 Maanshan Iron & Steel Company Limited (HKG:323).
Our data shows Maanshan Iron & Steel has a return on equity of 26% for the last year. One way to conceptualize this, is that for each HK$1 of shareholders’ equity it has, the company made HK$0.26 in profit.

How Do You Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Maanshan Iron & Steel:
26% = CN¥7.0b ÷ CN¥31.9b (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 earnings retained by the company, plus any capital paid in by shareholders. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE Signify?
ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.
Does Maanshan Iron & Steel 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 is clear from the image below, Maanshan Iron & Steel has a better ROE than the average (12%) in the metals and mining industry.
That’s what I like to see. I usually take a closer look when a company has a better ROE than industry peers. For example, I often check if insiders have been buying shares .
How Does Debt Impact 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 debt required for growth will boost returns, but will not impact the shareholders’ equity. That will make the ROE look better than if no debt was used.
