Markel Group Inc

“Markel compounds book value at ~15% annually through a self-reinforcing flywheel of specialty insurance float, long-duration equity investing, and industrial cash flows — all three engines simultaneously strengthening at a price of just 1.26x book and ~13x earnings, near the low end of its historical range. The primary risks are casualty reserve development and key-person dependency on Gayner, both real but insufficient to override an exceptional 35-year track record and a balance sheet with $18.6B of equity absorbing any near-term volatility. At today's price, a patient long-term investor gets a probable 2–3x compounder over a decade with limited risk of permanent capital loss.”
