Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ The rating is not equivalent to a margin of safety assessment.
The rating's value:
- Can initially assess company quality, but margin of safety is a 'price vs. value' question, not just quality
- A perfect 10-point quality company with an overpriced stock has no margin of safety
- The score combined with valuation data determines whether safety margin exists
Key limitations:
- Duan emphasizes 'a good company doesn't equal a good investment' — a high score means the company is good, not that the price is right
- AI can't accurately estimate intrinsic value, so it can't truly judge margin of safety magnitude
- Margin of safety requires conservative future cash flow estimates, but AI may default to consensus expectations (not conservative enough)
✅ Right approach: Combine the AI's quality score with your own valuation analysis. Good company (high score) + Good price (30%+ below conservative valuation) = a truly margin-of-safety investment.

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 “الإصرار على هامش الأمان”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.
