Basic Questions
What's the difference between Fisher's 'hold forever' and Buffett's approach?
Both masters advocate long-term holding with different emphases:
📊 Fisher vs Buffett:
- Fisher focuses more on growth potential: Never sell as long as the company keeps growing
- Buffett focuses more on valuation: Great companies must be bought at reasonable prices
Fisher's 'hold forever' three conditions:
1. ✅ Company's competitive advantage is still strengthening
2. ✅ Management's innovation capability persists
3. ✅ Large untapped market space remains
Sell only when these conditions no longer hold. Fisher said: 'If the right choice was made at purchase, the time to sell almost never comes.'

Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ The "hold-forever suitability" score must be treated with extreme caution — companies truly worth holding forever are exceedingly rare.
The rating's unique perspective:
- The score measures not whether the company is good now, but "will this company still be strong in 20 years"
- A high score doesn't mean you can buy and completely forget — Fisher emphasized continuously tracking whether fundamentals are deteriorating
- Compare against historical "hold forever" classics (like Coca-Cola, Procter & Gamble) to see where this company falls short
Core warnings:
- "Forever" in Fisher's era differs from today — accelerating technological change means moats are eroded faster
- AI cannot predict when disruptive technologies will emerge
- "Hold forever" doesn't mean "ignore sell signals" — if fundamentals deteriorate fundamentally, Fisher would sell decisively

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