Simply Wall St · 1d ago

Tanwan's (HKG:9890) stock is up by a considerable 7.9% over the past week. Given that the market rewards strong financials in the long-term, we wonder if that is the case in this instance. Particularly, we will be paying attention to Tanwan's ROE today.

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 other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

How Do You Calculate Return On Equity?

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 Tanwan is:

33% = CN¥1.1b ÷ CN¥3.3b (Based on the trailing twelve months to June 2025).

The 'return' is the yearly profit. That means that for every HK$1 worth of shareholders' equity, the company generated HK$0.33 in profit.

What Has ROE Got To Do With Earnings Growth?
