By way of learning-by-doing, we'll look at ROE to gain a better understanding of Taiwan High Speed Rail Corporation (TWSE:2633).

How To Calculate Return On Equity?

ROE 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 Taiwan High Speed Rail is:

9.0% = NT$6.5b ÷ NT$72b (Based on the trailing twelve months to December 2024).

The 'return' is the yearly profit. Another way to think of that is that for every NT$1 worth of equity, the company was able to earn NT$0.09 in profit.

Does Taiwan High Speed Rail 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, Taiwan High Speed Rail has a better ROE than the average (7.3%) in the Infrastructure 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.

How Does Debt Impact Return On Equity?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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 required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining Taiwan High Speed Rail's Debt And Its 9.0% Return On Equity

It seems that Taiwan High Speed Rail uses a huge volume of debt to fund the business, since it has an extremely high debt to equity ratio of 3.24. The combination of a rather low ROE and high debt to equity is a negative, in our book.

Conclusion

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 around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. 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.
