Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ The scoring threshold for concentrated bets is much higher than for diversified investing.
The rating's value:
- Ackman's concentration demands high conviction — companies scoring below 8 aren't worth concentrating on
- Quick elimination of unqualified candidates, but making the cut is just the beginning
- Compare against your core holdings' scores to judge if new opportunities warrant 'replacing' existing positions
Key limitations:
- Ackman's concentration decisions rest on 'I understand this better than the market' — a high AI score doesn't mean you have that conviction
- Concentration requires considering portfolio correlation — even high individual scores don't justify inclusion if highly correlated with existing holdings
- Ackman's concentration in Valeant led to massive losses — concentration risk is real, and AI scores can't eliminate it
✅ Right approach: A high AI score is necessary but not sufficient — you must confirm you have an information edge and that the thesis survives extreme stress tests.

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