Admit Mistakes - Prompt de Análisis IA

Basic Questions

What major investment mistakes has Buffett made and how did he handle failure?
Buffett has publicly admitted multiple errors:

❌ Classic mistakes:
1. Buying Berkshire Hathaway itself — a declining textile mill
2. Missing Amazon and Google — outside his circle of competence
3. Investing in Dexter Shoes — paid with Berkshire stock, losing billions

✅ His approach:
- Publicly admits mistakes in annual shareholder letters
- Analyzes root causes (rather than making excuses)
- Turns every mistake into a decision framework improvement

Usage Tips

Is the AI's 1-10 rating reliable?
⚠️ AI's "mistake identification score" reflects how much the investment thesis has weakened, not a stock price prediction.

How to interpret:
- **8-10 (thesis strong)**: Original buy rationale largely intact — don't panic over short-term fluctuations, continue holding
- **5-7 (cracks appearing)**: Some buy reasons shaken — seriously examine the specific issues AI identified, consider reducing position
- **1-4 (thesis collapsed)**: Original investment logic severely undermined — seriously consider cutting losses

Buffett's wisdom: Selling a mistaken investment isn't admitting defeat — it's freeing capital for better opportunities. Don't let ego block rational decisions.

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 “Admite los Errores”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.
