Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). To keep the lesson grounded in practicality, we'll use ROE to better understand Essex Bio-Technology Limited (HKG:1061).
Essex Bio-Technology has a ROE of 25%, based on the last twelve months. One way to conceptualize this, is that for each HK$1 of shareholders' equity it has, the company made HK$0.25 in profit.

How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Essex Bio-Technology:
25% = HK$231m ÷ HK$929m (Based on the trailing twelve months to December 2018.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. 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 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. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Essex Bio-Technology 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Essex Bio-Technology has a superior ROE than the average (15%) company in the Biotechs 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 .
The Importance Of Debt To 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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.
Essex Bio-Technology's Debt And Its 25% ROE
Although Essex Bio-Technology does use debt, its debt to equity ratio of 0.20 is still low. When I see a high ROE, fuelled by only modest debt, I suspect the business is high quality. 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.
