Short answer

How can I use AI to stress test my investment thesis?

Your AI uses the Munger Latticework Prover to hunt for flaws in your reasoning by simulating worst-case scenarios. It identifies specific points of fragility in your thesis so you can decide if the risk is worth the reward. You get a clear view of where your logic breaks under pressure.

The results.

Where your analysis lands.

The AI processes your thesis and maps the results to these four areas.

CRITICAL

Fragility points identified

The AI flags specific assumptions that, if wrong, would break the entire investment case. You get a list of the most dangerous points of failure.

MARGIN

Safety buffer check

It calculates how much room you have for error before the thesis fails. This shows you if your margin of safety is actually wide enough.

LOGIC

Reasoning gaps found

The AI spots leaps in logic or missing connections between your data and your conclusion. It highlights where you're assuming too much without evidence.

HUMAN

Final judgment required

The AI provides the bear case, but you decide if the counter-arguments are convincing. You maintain full control over the final buy or sell decision.

The workflow

What your AI does when the thesis arrives.

The AI acts as a professional contrarian to challenge your conviction.

  1. Deconstruct the thesis

    The AI breaks your investment note into individual, testable assumptions and core drivers.

  2. Simulate the bear case

    It runs a simulation where your primary assumptions fail to see how the valuation reacts.

  3. Map the lattice

    The agent checks if your thesis holds up across different mental models and business principles.

  4. Identify fragility

    The AI isolates the specific variables that create the most risk for your position.

FAQ

How this task behaves.

  • 01

    Can the AI execute trades based on the stress test?

    No. The AI only analyzes your thesis and identifies risks. You must make all execution decisions yourself.

  • 02

    Does the AI rewrite my original investment notes?

    No. The AI reads your notes to find flaws, but it does not modify your original files.

  • 03

    Will the AI find real-time market data?

    No. This tool analyzes the logic and assumptions within the documents you provide.

  • 04

    Can I use this with any AI client?

    Yes, you can use it with any MCP-compatible client like Claude, Cursor, or Windsurf.

  • 05

    Does the AI decide if an investment is good or bad?

    No. The AI provides the bear case and identifies fragility, but the final judgment is always yours.
