How the answer is built
Every Buffett answer is scored against the same five pillars Buffett has talked about for fifty years. Each pillar is rated 0–20; the total becomes the 0–100 score.
- 01
Wide economic moat
Brand, scale, switching costs, network effects - anything that keeps competitors from eating into margins.
- 02
Honest, able management
Capital allocators who treat shareholders like partners - buybacks at low prices, candid letters, skin in the game.
- 03
Consistent earning power
Ten-year ROIC ≥ 12%, predictable free cash flow, low capex relative to earnings.
- 04
Fair price, margin of safety
Owner-earnings yield that beats the long bond, with enough cushion that a bad year doesn't break the thesis.
- 05
Inside the circle of competence
If it can't be explained on a napkin - what they sell, who buys, why they keep buying - Buffett skips it.
