How Do You Calculate Return On Equity?

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 Jolywood (Suzhou) Sunwatt is:

12% = CN¥650m ÷ CN¥5.2b (Based on the trailing twelve months to September 2023).

The 'return' is the amount earned after tax over the last twelve months. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.12 in profit.

Does Jolywood (Suzhou) Sunwatt Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for 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, Jolywood (Suzhou) Sunwatt has a higher ROE than the average (6.1%) in the Semiconductor industry.

That's clearly a positive. Bear in mind, a high ROE doesn't always mean superior financial performance. 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

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 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 Jolywood (Suzhou) Sunwatt's Debt And Its 12% Return On Equity

Jolywood (Suzhou) Sunwatt does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.24. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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 ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
