The Moat Index · Top 100
The widest moats in the scored universe.
The Index is the Top 100 — ranked from 3,096 companies scored nightly from primary SEC filings, 0–100 on five investor questions. Higher means a more durable business. The method is fully public; the full universe is in the A–Z directory and the sector hubs.
The Index publishes here once the first scoring run over the filings completes. The scoring engine and append-only history are live; the leaderboard fills as companies are scored.
