What You Can Build

Review a Deep-Value Stock

Assess one ticker against Graham criteria, liquidation value, safety margin, and value-trap indicators.

Research Business Quality

Evaluate a company moat, financial durability, management record, valuation, and expected holding period.

Build a Candidate List

Screen an index or watchlist for Graham bargains or Buffett-style quality compounders.

Try These Prompts

Check One Graham Candidate
Analyze {ticker} with the Graham framework. Show NCAV, valuation filters, safety margin, holding period, value-trap warnings, and sources.
Assess One Buffett Candidate
Analyze {ticker} using the Buffett moat framework. Rate each dimension, separate business quality from price, and cite every material figure.
Screen a Market Universe
Screen {index_or_watchlist} in {market} for {Graham_or_Buffett} candidates. Use default thresholds, explain exclusions, and return ranked results with sources.
Compare Frameworks with Sensitivity
Reconcile statements for {ticker}, then compare Graham and Buffett conclusions. Test {threshold_changes}, identify conflicting signals, and explain data limitations.

Best Practices

  • Provide a market-qualified ticker or a clearly defined index or watchlist.
  • State any threshold changes before screening so results remain comparable.
  • Review the source appendix and data limitations before using any score.

Avoid

  • Do not treat a high score as a direct buy or sell recommendation.
  • Do not compare NCAV across banks, insurers, REITs, or other excluded financial structures.
  • Do not use stale or unreconciled financial statements when current data is available.
