Sumec (SHSE:600710) has had a great run on the share market with its stock up by a significant 15% over the last three months. Since the market usually pay for a company's long-term fundamentals, we decided to study the company's key performance indicators to see if they could be influencing the market. Particularly, we will be paying attention to Sumec's ROE today.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Is ROE Calculated?

ROE 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 Sumec is:

23% = CN¥3.1b ÷ CN¥14b (Based on the trailing twelve months to March 2024).

The 'return' is the profit over the last twelve months. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.23 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company's earnings growth potential. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

A Side By Side comparison of Sumec's Earnings Growth And 23% ROE

To start with, Sumec's ROE looks acceptable. Especially when compared to the industry average of 6.2% the company's ROE looks pretty impressive. Probably as a result of this, Sumec was able to see a decent growth of 19% over the last five years.

Next, on comparing with the industry net income growth, we found that Sumec's growth is quite high when compared to the industry average growth of 11% in the same period, which is great to see.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. It's important for an investor to know whether the market has priced in the company's expected earnings growth (or decline). This then helps them determine if the stock is placed for a bright or bleak future. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Sumec is trading on a high P/E or a low P/E, relative to its industry.
