Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ The rating may overvalue complex businesses.
The rating's value:
- Simple, predictable companies typically score more consistently — because AI can 'understand' them more easily too
- If the AI's analysis is full of uncertain assumptions and complex conditionals, the company may not be 'simple' enough
- Companies with low score volatility are usually more predictable than those with high volatility
Key limitations:
- Complex companies' AI scores may look fine, but Ackman would say 'if you need a complex Excel model to understand it, it's too complicated'
- The score can't reflect a business model's 'intuitive understandability' — Ackman's core simplicity criterion
- Tech and cyclical companies may score high but fail the 'predictable' standard
✅ Right approach: If after reading the AI analysis you think 'this is too complex, I don't quite get it,' the company is probably not simple and predictable enough. Trust your instinct.

Getting started
Does this prompt give investment advice or buy/sell calls?
No. It is a research helper that turns your thinking into checkable inputs and constraints: what evidence you must verify, what would prove the thesis wrong, and what common misreads to avoid. Treat the output as a draft, not a signal. Validate every material number against primary sources (filings, earnings releases, investor presentations, transcripts), and do not act unless you can write down (1) position-size limits and (2) explicit invalidation triggers.
What inputs should I provide for a reliable result?
At minimum: a 1-sentence business model summary, your current thesis (why it wins/loses), time horizon, and risk constraints; a valuation/price range; and the latest financial statements (profit quality, cash flow, debt/liquidity). Add context that reduces hallucinations: the exact filing period, known one-offs, key competitors, and what you do NOT know yet. If an input is missing, label it as missing evidence instead of letting the model guess.
Validation and boundaries
How do I validate the output?
Validate falsifiable claims one by one. Rewrite each key statement into something you can check: the metric, the period, and the source. Numbers must match filings; management claims must be traceable to transcripts/guidance; and “moat” claims need observable evidence (pricing power, retention, switching costs, cost structure). Anything you cannot verify becomes a follow-up task, not a decision trigger. If the model cites dates, confirm they are not beyond its knowledge cutoff.
When should I NOT act on the output?
If you cannot write down invalidation triggers, a position-size cap, or primary-source evidence for the key claims behind “Simple, Predictable Businesses”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.
