While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Taiwan Advanced Nanotech Inc. (GTSM:6797), by way of a worked example.
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.
How Is ROE Calculated?
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 Taiwan Advanced Nanotech is:
24% = NT$56m ÷ NT$229m (Based on the trailing twelve months to June 2020).
The 'return' is the income the business earned over the last year. Another way to think of that is that for every NT$1 worth of equity, the company was able to earn NT$0.24 in profit.
Does Taiwan Advanced Nanotech Have A Good Return On Equity?
Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Taiwan Advanced Nanotech has a superior ROE than the average (11%) in the Medical Equipment industry.
That's clearly a positive. 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
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 case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
Taiwan Advanced Nanotech's Debt And Its 24% ROE
While Taiwan Advanced Nanotech does have some debt, with a debt to equity ratio of just 0.31, we wouldn't say debt is excessive. The combination of modest debt and a very impressive ROE does suggest that the business is high quality. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
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.
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.
