Buffett-fit Score

What it is\nA composite score running every stock through Buffett's actual public framework — published in his shareholder letters, his Columbia lectures, and decades of Berkshire Hathaway annual reports — and asking: how many of the rules does this stock pass?\n\nThe rules cluster into five pillars:\n1. Moat — does the business have a structural competitive advantage?\n2. Durability — will customers want this product in 10+ years?\n3. Management — is capital being allocated well? (buybacks, debt discipline, no empire-building)\n4. Balance Sheet — could this business survive a recession without dilution or distress?\n5. Valuation — at the current price, is the implied future return attractive?\n\n## How to read it\n- 80–100: passes most of Buffett's checklist. Worth a hard look.\n- 65–79: passes the quality bars but probably stretched on valuation, OR a fair-priced business with a moderate quality concern.\n- 50–64: mixed. Failing on at least one major pillar.\n- < 50: doesn't fit Buffett's criteria. May still be a great investment under a different framework (Lynch, Greenblatt) — just not this one.\n\n## What it's NOT\nThis isn't Warren Buffett's actual stock-pick. He's never seen the algorithm. It's a pattern-match against his publicly-documented framework — useful as a screen, not as a recommendation.
