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). We’ll use ROE to examine The Hong Kong and China Gas Company Limited (HKG:3), by way of a worked example.
Hong Kong and China Gas has a ROE of 15%, 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$0.15 in profit.
How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Hong Kong and China Gas:
15% = HK$9.3b ÷ HK$70b (Based on the trailing twelve months to December 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. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.
What Does ROE Signify?
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 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 being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.
Does Hong Kong and China Gas Have A Good Return On Equity?
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. Pleasingly, Hong Kong and China Gas has a superior ROE than the average (11%) company in the Gas Utilities industry.
That’s what I like to see. We think a high ROE, alone, is usually enough to justify further research into a company. For example you might check if insiders are buying shares.
The Importance Of Debt To Return On Equity
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 first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
Combining Hong Kong and China Gas’s Debt And Its 15% Return On Equity
While Hong Kong and China Gas does have some debt, with debt to equity of just 0.57, we wouldn’t say debt is excessive. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
The Bottom Line On ROE
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 around the same level of debt to equity, and one has a higher ROE, I’d generally prefer the one with higher ROE.
But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
