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. To keep the lesson grounded in practicality, we'll use ROE to better understand HKT Trust and HKT Limited (HKG:6823).

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Do You Calculate Return On Equity?

Return on equity can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for HKT Trust and HKT is:

14% = HK$5.0b ÷ HK$35b (Based on the trailing twelve months to December 2023).

The 'return' is the yearly profit. Another way to think of that is that for every HK$1 worth of equity, the company was able to earn HK$0.14 in profit.

Does HKT Trust and HKT 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, HKT Trust and HKT has a superior ROE than the average (6.1%) in the Telecom industry.

That is a good sign. With that said, a high ROE doesn't always indicate high profitability. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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.

HKT Trust and HKT's Debt And Its 14% ROE

HKT Trust and HKT does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.28. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Summary

Return on equity is useful for comparing the quality of different businesses. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
