# Why Micro-Mechanics (Holdings) Ltd. (SGX:5DD) Looks Like A Quality Company

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Micro-Mechanics (Holdings) Ltd. (SGX:5DD).

Micro-Mechanics (Holdings) has a ROE of 22%, based on the last twelve months. Another way to think of that is that for every SGD1 worth of equity in the company, it was able to earn SGD0.22.

### How Do I Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Micro-Mechanics (Holdings):

22% = S\$13m Ã· S\$58m (Based on the trailing twelve months to June 2019.)

Most readers would understand what net profit is, but itâ€™s worth explaining the concept of shareholdersâ€™ equity. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

### What Does Return On Equity Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

### Does Micro-Mechanics (Holdings) Have A Good Return On Equity?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Micro-Mechanics (Holdings) has a better ROE than the average (14%) in the Semiconductor industry.

That is a good sign. I usually take a closer look when a company has a better ROE than industry peers. One data point to check is if insiders have bought shares recently.

### How Does Debt Impact Return On Equity?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), or debt. 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

### Micro-Mechanics (Holdings)'s Debt And Its 22% ROE

One positive for shareholders is that Micro-Mechanics (Holdings) does not have any net debt! Its ROE already suggests it is a good business, but the fact it has achieved this -- and doesn't borrowings -- makes it worthy of further consideration, in my view. After all, when a company has a strong balance sheet, it can often find ways to invest in growth, even if it takes some time.

### The Bottom Line On ROE

Return on equity is one way we can compare the business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
