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 China Health Group Inc. (HKG:8225).
China Health Group has a ROE of 54%, 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$0.54 in profit.
How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for China Health Group:
54% = CN¥24m ÷ CN¥45m (Based on the trailing twelve months to June 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. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.
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. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.
Does China Health Group Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for 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, China Health Group has a better ROE than the average (9.7%) in the Life Sciences industry.
That is a good sign. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.
The Importance Of Debt To Return On Equity
Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. 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.
China Health Group's Debt And Its 54% ROE
China Health Group has a debt to equity ratio of just 0.034, which is very low. When I see a high ROE, fuelled by only modest debt, I suspect the business is high quality. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Key Takeaway
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. If two companies have the same ROE, then I would generally prefer the one with less debt.
But when a business is high quality, the market often bids it up to a price that reflects this. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
