Basic Questions

What is "Circle of Competence" and why does it matter?
Circle of competence refers to areas you truly understand — not "heard of" but "can predict outcomes."

Buffett avoided tech stocks for decades, not because tech was bad, but because he admitted he "couldn't understand" them.

Why it matters:
1. Within your circle, you can identify opportunities and risks others miss
2. Outside your circle, you're relying on luck
3. Most investor losses come from investing in things they don't understand

Buffett says: "Knowing what you know and knowing what you don't know — that is true knowledge."

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