Basic Questions
Why did Graham recommend index funds for average investors?
Graham categorized investors into two types:
🔹 Defensive investors: Lack time, energy, or ability for deep research
🔹 Enterprising investors: Willing to invest significant time in value analysis
For most people (defensive investors), he advised:
1. Don't overestimate your stock-picking ability
2. Index funds automatically diversify risk
3. Low fees mean significantly less return loss over time
4. Fund managers who beat the market are rare and hard to identify in advance

Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ AI's index fund strategy score reflects the reasonableness of your allocation, not market direction prediction.
How to interpret:
- **8-10 (excellent allocation)**: Low fees, small tracking error, high diversification — meets Graham's standards for defensive investors
- **5-7 (room for optimization)**: Basically sound but improvable — perhaps fees too high or over-concentrated in one market
- **1-4 (needs adjustment)**: Unbalanced allocation, excessive fees, or overly niche index products
One of Graham's most important late-career insights: For most investors, low-cost index funds are the wisest choice. AI helps confirm your execution matches this wisdom.

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