Basic Questions
Why is profit margin a key indicator of company quality?
Fisher focused on margins because they reflect core competitiveness:
📊 What margins reveal:
1. High margin = Pricing power (customers pay for value)
2. Sustained high margin = Moat (competitors can't undercut)
3. Rising margin = Scale effects or innovation at work
⚠️ Watch out:
- Margins only matter when compared to peers
- Suddenly rising margins may come from cutting R&D (sacrificing the future)
- Excessively high margins attract competition — the key is defending against it

Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ Margin ratings should focus on "trends" rather than "absolute values" — normal margin levels vary enormously across industries.
The rating's unique perspective:
- Fisher cared not about how high margins are, but whether they're continuously improving or at least stable
- A declining margin trend is more dangerous than low margins — the former signals deteriorating competitiveness
- Comparing the highest and lowest margin companies in an industry and understanding why matters more than absolute numbers
Usage notes:
- Some high-growth companies may have temporarily lower but improving margins — this is acceptable in Fisher's framework
- AI may overweight current margins while underestimating future improvement potential
- One-time charges/gains can distort margin data — focus on adjusted margin trends

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 “Márgenes de Beneficio Valiosos”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.
