How Do You Calculate Return On Equity?

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 White Mountains Insurance Group is:

6.7% = US$280m ÷ US$4.2b (Based on the trailing twelve months to September 2023).

The 'return' is the yearly profit. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.07 in profit.

What Is The Relationship Between ROE And Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

White Mountains Insurance Group's Earnings Growth And 6.7% ROE

When you first look at it, White Mountains Insurance Group's ROE doesn't look that attractive. A quick further study shows that the company's ROE doesn't compare favorably to the industry average of 14% either. Therefore, it might not be wrong to say that the five year net income decline of 13% seen by White Mountains Insurance Group was probably the result of it having a lower ROE. We believe that there also might be other aspects that are negatively influencing the company's earnings prospects. Such as - low earnings retention or poor allocation of capital.

So, as a next step, we compared White Mountains Insurance Group's performance against the industry and were disappointed to discover that while the company has been shrinking its earnings, the industry has been growing its earnings at a rate of 9.0% over the last few years.

Earnings growth is a huge factor in stock valuation. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. Doing so will help them establish if the stock's future looks promising or ominous. 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 White Mountains Insurance Group is trading on a high P/E or a low P/E, relative to its industry.
