WTMWhite Mountains Insurance Group, Ltd.
Is the price fair?
Cheap against its own history. That is the only one of 3 checks this filer's data supports, so take it as a single data point rather than a settled answer.
Cheap vs its own history: P/E 5.1 vs a 8.0 median over 36 quarters (−36% vs median).
Where this answer is blind. The growth-implied estimate assumes a fixed discount rate; capital-heavy sectors look structurally rich on it.
