The Moat Index

The widest moats in the scored universe.

The 100 widest Utilities moats — of 101 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.

Current score records: moat-index@3.0.0.

Every scored Utilities company, not just these 100 →

The map — moat vs. price · Utilities

Dividers sit at Moat Score 80 (a Wide moat) and at 10% below conservative value — the same bars the methodology uses. The x-axis starts at 55 because this set is the top of the Index; the vertical scale is compressed beyond ±25% (every tick shows its true value), and anything priced more than 26× value sits on the "≤ −2500%" line — hover a dot (or open the table) for its exact reading. 23 companies have no recent price data and aren't plotted — the table view lists them.
