How To Calculate Return On Equity?

The formula for ROE is:

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

So, based on the above formula, the ROE for WT Microelectronics is:

8.1% = NT$7.6b ÷ NT$93b (Based on the trailing twelve months to September 2024).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each NT$1 of shareholders' capital it has, the company made NT$0.08 in profit.

Does WT Microelectronics 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. You can see in the graphic below that WT Microelectronics has an ROE that is fairly close to the average for the Electronic industry (8.9%).

That isn't amazing, but it is respectable. While at least the ROE is not lower than the industry, its still worth checking what role the company's debt plays as high debt levels relative to equity may also make the ROE appear high. If a company takes on too much debt, it is at higher risk of defaulting on interest payments. To know the 2 risks we have identified for WT Microelectronics visit our risks dashboard for free.

How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining WT Microelectronics' Debt And Its 8.1% Return On Equity

It's worth noting the high use of debt by WT Microelectronics, leading to its debt to equity ratio of 1.27. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. 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. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

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.
