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 Lianhe Sowell International Group is:

25% = US$2.5m ÷ US$9.8m (Based on the trailing twelve months to September 2024).

The 'return' is the income the business earned over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.25.

Does Lianhe Sowell International Group 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, Lianhe Sowell International Group has a higher ROE than the average (9.9%) in the Electronic industry.

That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk. Our risks dashboard should have the 3 risks we have identified for Lianhe Sowell International Group.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. 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.

Combining Lianhe Sowell International Group's Debt And Its 25% Return On Equity

Lianhe Sowell International Group has a debt to equity ratio of 0.24, which is far from excessive. Its ROE is very impressive, and given only modest debt, this suggests the business is high quality. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.

Conclusion

Return on equity is one way we can compare its business quality of different companies. 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. 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.
