The Moat Index

Score my portfolio.

How much moat do you actually own? Enter your tickers and weights — percentages or dollar amounts — and we’ll weight-average the Moat Scores of your covered holdings into one number (always shown with how much of your portfolio that covers), show your moat-tier and price-vs-value mix, and put your portfolio side by side with Berkshire’s scored 13F.

Your portfolio never leaves this browser: holdings are saved in local storage on your device — no account, no email. Scoring only sends each ticker symbol to look up its public score; your weights and amounts are never transmitted, consistent with our privacy notice.

Enter your holdings — ticker plus how much of your portfolio each one is — and we’ll weight-average their Moat Scores into one number, show your moat and valuation mix, and put it side by side with Berkshire’s latest 13F. Everything stays in this browser.

Saved in this browser only — no account, nothing uploaded. Only tickers and weights are stored. Each ticker is then checked against the live scored universe.

Educational only — a weighted score describes the businesses you hold through our published lens; it is not investment advice, a recommendation, or a prediction of returns. Scores come from primary SEC filings and cover large U.S. operating companies; financials are excluded by design. See the methodology and disclaimer.
