Investment Thesis Construction OS

Turn a folder of research notes into a thesis you can actually be wrong about: one falsifiable core claim, the mechanism chain behind it, base-rate reality checks on every link, the disconfirming evidence you would need to see, numeric kill criteria with action tiers, and a monitoring schedule that tells you when the thesis has broken. A structuring system for your own analysis — not investment advice.

A 4-step agentic workflow pack for finance built to run with ChatGPT, Claude, and Gemini. Open the Markdown files, fill the variables, and paste into your model. Most buyers get a reviewable result in about 90 minutes.

  • Compress messy research notes into one sentence you could later be proven wrong about
  • Expose the mechanism chain link by link, with evidence scored 1-5 against explicit anchors
  • Name your real edge honestly - information, analytical, time horizon, behavioral, or none
  • Reality check every link against its reference class before conviction hardens
  • Generate the disconfirming observations you would need to see, with sources and timing
  • Convert soft doubts into numbered kill criteria with four pre-committed action tiers
  • Build a monitoring schedule with named owners, so a dying thesis surfaces on a calendar
  • Every prompt ends with an explicit not-investment-advice scope notice

FAQ

How long does it take to use Investment Thesis Construction OS?
Most buyers finish in a few minutes: open the prompt file, fill the variables, and paste into your model. The first run is the slowest because you decide variable values; reuse is instant.
What if I get stuck?
Email support@promptscart.com. Free basic support is included with every purchase, and you'll get a reply from our team within 24 hours. If you need help adapting variables or output, we can schedule a call.
Do I need a paid plan with ChatGPT?
The prompt works on free tiers of ChatGPT, Claude, and Gemini. Heavy use can hit free-tier limits; paid plans get longer context and faster responses, but the prompt itself is the value.
Can I customize the prompt?
Yes, completely. You own the prompt files: edit the role framing, add variables, swap output sections, fork it to match your brand voice. Support can help you plan customizations over email.
What if it doesn't work for me?
Refund as per our Refund Policy (https://promptscart.com/refund-policy). Or add Prompt Customization Service at checkout for help adapting variables and output to your workflow.
