The Moat Index · Filing-derived evidence, kept in history.

Educational use only

An independent educational research product built around the Moat Index: filing-derived scores, company Track Records, screening, point-in-time backtests, a rules-only paper portfolio, and portfolio tools. Scores are computed model outputs, not analyst ratings. Nothing here is investment, legal, or tax advice, and we are not affiliated with Warren Buffett or Berkshire Hathaway.
