# Based On Its ROE, Is Viomi Technology Co., Ltd (NASDAQ:VIOT) A High Quality Stock?

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 Viomi Technology Co., Ltd (NASDAQ:VIOT), by way of a worked example.

Our data shows Viomi Technology has a return on equity of 7.3% for the last year. One way to conceptualize this, is that for each \$1 of shareholders' equity it has, the company made \$0.073 in profit.

### How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Viomi Technology:

7.3% = CNÂ¥88m Ã· CNÂ¥1.1b (Based on the trailing twelve months to March 2019.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

### What Does ROE Mean?

Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

### Does Viomi Technology 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. If you look at the image below, you can see Viomi Technology has a lower ROE than the average (13%) in the Consumer Durables industry classification.

That certainly isn't ideal. We'd prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Still, shareholders might want to check if insiders have been selling.

### How Does Debt Impact Return On Equity?

Companies usually need to invest money 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 use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

### Viomi Technology's Debt And Its 7.3% ROE

Viomi Technology is free of net debt, which is a positive for shareholders. Even though I don't think its ROE is that great, I think it's very respectable when you consider it has no debt. After all, with cash on the balance sheet, a company has a lot more optionality in good times and bad.

### In Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
