How Do You Calculate Return On Equity?
Return on equity 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 China Wafer Level CSP is:
14% = CN¥530m ÷ CN¥3.7b (Based on the trailing twelve months to September 2021).
The 'return' is the income the business earned over the last year. Another way to think of that is that for every CN¥1 worth of equity, the company was able to earn CN¥0.14 in profit.
Does China Wafer Level CSP Have A Good ROE?
Arguably the easiest way to assess company's ROE is to compare it with the average in 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, China Wafer Level CSP has a higher ROE than the average (9.0%) in the Semiconductor industry.
That's clearly a positive. However, bear in mind that a high ROE doesn't necessarily indicate efficient profit generation. 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 case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
China Wafer Level CSP's Debt And Its 14% ROE
China Wafer Level CSP has a debt to equity ratio of just 0.0038, which is very low. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.
Summary
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 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
