Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Crystal Growth & Energy Equipment Co.,Ltd. (SHSE:688478), by way of a worked example.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

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 Crystal Growth & Energy EquipmentLtd is:

3.8% = CN¥59m ÷ CN¥1.6b (Based on the trailing twelve months to September 2023).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each CN¥1 of shareholders' capital it has, the company made CN¥0.04 in profit.

Does Crystal Growth & Energy EquipmentLtd 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. If you look at the image below, you can see Crystal Growth & Energy EquipmentLtd has a lower ROE than the average (6.4%) in the Semiconductor industry classification.

Unfortunately, that's sub-optimal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved. Our risks dashboard should have the 3 risks we have identified for Crystal Growth & Energy EquipmentLtd.

Why You Should Consider Debt When Looking At ROE

Virtually all companies need money to invest in the business, to grow 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 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.

Combining Crystal Growth & Energy EquipmentLtd's Debt And Its 3.8% Return On Equity

Crystal Growth & Energy EquipmentLtd has a debt to equity ratio of just 0.012, which is very low. Its ROE is rather low, and it does use some debt, albeit not much. That's not great to see. 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.

Conclusion

Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. 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 when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
