Price-to-Earnings of 4.5x: Is it justified?

White Mountains Insurance Group is currently trading at a P/E of 4.5x, with a last close price of $2,113.40 and past earnings growth that has been very large.

The P/E ratio compares the company’s share price to its earnings per share. For White Mountains Insurance Group, this offers a simple way to relate the current share price to the earnings power highlighted by recent results.

WTM is flagged as good value based on this 4.5x P/E when compared with both its peer average of 9.3x and the wider US Insurance industry average of 11.5x. Earnings growth over the past year has also been very large compared with both its own 5-year pace and the industry, while net profit margins and return on equity sit in a range that some investors may consider consistent with a mature but profitable insurance group.

Result: Price-to-Earnings of 4.5x (UNDERVALUED)

However, White Mountains Insurance Group still carries risks around its complex mix of segments and the recent short term share price weakness, which could challenge the current value case.

Another View on White Mountains Insurance Group’s Valuation

The earlier P/E comparison presents White Mountains Insurance Group as relatively good value, while the SWS DCF model points to a different reference point. It suggests a fair value of about $3,583.40 per share, which is above the current $2,113.40 price and indicates the stock appears undervalued on that basis.
