Is WTM undervalued?

At 2,376.30 (close of 5 Nov 2026), WTM trades 73% below the GLS average fair value of 8,914.92. That average comes from 8 models run on the latest filings, and 7 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns White Mountains Insurance Group, Ltd. the full Value points in the Wheel Score - and a closer look at what the market is pricing in.

The 8 models disagree widely: DDM gives 14.71 while GLS Growth gives 28,428.34. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.

Ranked against every other company we cover, neither cheapness nor growth clearly wins for WTM, so the nightly engine files it under Blend (value score 84, growth score 78, out of 100).

Nine valuation models for WTM

Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

Quality and financial health

Financial health is average - WTM passes 5 of the nine Piotroski tests, which falls one point short of the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is 6.7 out of 10: a record that is solid on some of the four parts the score weighs (returns on capital, pricing power, lasting growth, balance sheet) and weaker on others.

Returns on capital are high - ROIC 17.7%, ROE 20.4%, ROA 9.0% - with debt at 0.15 times equity and a free-cash-flow yield of 7.5%.

The dividend yield is 0.04% with a payout ratio of 0% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Product and Service, Other 100% (quarter Q2 FY2026).

Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 1/10 on the GLS smart-money scales.

Wheel Score 34: No options

WTM has no listed options in the nightly snapshot, so there is nothing to sell and the stock cannot be wheeled however good the business. It fails the first Wheel Trade Filter (options that actually trade), so the score stays under 70 and is shown as "No options" (34 here). The valuation and quality numbers still apply to owning the shares outright.

Volume runs at 24k shares a day on a market cap of $5.7B, with a beta of 0.28 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that good.
