Is Taiwan High Speed Rail Corporation's (TPE:2633) ROE Of 7.6% Impressive?

While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we'll use ROE to better understand Taiwan High Speed Rail Corporation (TPE:2633).

How Is ROE Calculated?

The formula for return on equity is:

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

So, based on the above formula, the ROE for Taiwan High Speed Rail is:

7.6% = NT$5.1b ÷ NT$68b (Based on the trailing twelve months to September 2020).

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$0.08 in profit.

Does Taiwan High Speed Rail Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As you can see in the graphic below, Taiwan High Speed Rail has a higher ROE than the average (5.7%) in the Infrastructure industry.

That is a good sign. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

Why You Should Consider Debt When Looking At ROE

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 required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

Combining Taiwan High Speed Rail's Debt And Its 7.6% Return On Equity

We think Taiwan High Speed Rail uses a significant amount of debt to maximize its returns, as it has a significantly higher debt to equity ratio of 4.09. The combination of a rather low ROE and high debt to equity is a negative, in our book.

Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

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. So I think it may be worth checking this free this detailed graph of past earnings, revenue and cash flow.
