Usage Tips
Can AI accurately assess management quality?
⚠️ Management assessment is the "softest" part of analysis — AI can analyze data but not judge character.
Value:
- Quantitative analysis of track records and capital allocation returns
- Objective data on insider transactions and compensation changes
- Comparing operational efficiency across management teams
Limitations:
- Robertson personally interviewed every CEO for integrity, passion, leadership — AI can't replace this
- Hidden issues (fraud, conflicts of interest) often don't show in data
- AI may over-rely on past performance, but "good past management" may have become complacent
✅ Use AI for management "health reports" (quantitative), but final judgment needs public statements, industry reputation, and your intuition. Robertson said: "I invest in people first, then companies."

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