How Do You 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 Lvji Technology Holdings is:

24% = CN¥161m ÷ CN¥665m (Based on the trailing twelve months to December 2019).

The 'return' is the yearly profit. That means that for every HK$1 worth of shareholders' equity, the company generated HK$0.24 in profit.

Does Lvji Technology Holdings Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Lvji Technology Holdings has a higher ROE than the average (9.2%) in the Software industry.

That's what we like to see. With that said, a high ROE doesn't always indicate high profitability. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

The Importance Of Debt To Return On Equity

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. 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.

Lvji Technology Holdings' Debt And Its 24% ROE

Shareholders will be pleased to learn that Lvji Technology Holdings has not one iota of net debt! Its high ROE already points to a high quality business, but the lack of debt is a cherry on top. After all, with cash on the balance sheet, a company has a lot more optionality in good times and bad.
