Basic Questions

Why does Buffett make "never lose money" his Rule #1?
This isn't meant literally — it's an investing mindset:

1. Math of compounding: A 50% loss requires a 100% gain to break even
2. Psychological protection: Large losses lead to panic decisions
3. Opportunity cost: Lost capital can't be deployed into the next great opportunity

Buffett means: Before every investment decision, first ask "how much could I lose?" rather than "how much could I gain?"

Usage Tips

Is the AI's "Safety Scale" rating (1-10) reliable?
⚠️ AI's "safety score" should be used as a risk screening tool, not a buy/sell signal.

How to interpret correctly:
- **8-10 points**: Financial fortress companies with extremely low permanent loss risk, but still check if valuation is excessive
- **5-7 points**: Some defensive strength but with weak spots — focus on reviewing the specific risk items AI identified
- **1-4 points**: Significant risk of permanent capital loss — avoid unless you have a special informational edge

Key reminder: AI may underestimate "black swan" risks (fraud, sudden policy changes). A high score doesn't mean zero risk. Combine AI scoring with your own judgment on management integrity.

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 “Nunca Pierdas Dinero”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.
