Berkshire Hathaway Inc BRK-B

Moat holds this up; Valuation is the soft spot.

The price needs 11.0% growth a year for ten years. The AI thinks 6.0% is achievable, at a 9.5% margin.

Berkshire trades at a price that assumes faster long-term growth than its insurance float and diversified businesses are likely to deliver. The strong moat from cheap permanent capital and proven capital allocation provides a solid floor, but the math shows current valuation leaves little room for error on growth or margins. Evidence includes the gap between required and achievable growth plus consistent owner earnings generation. Main caveat is execution risk during the post-Buffett transition.
