Prompt
Create Bull And Bear Cases
Use this when you need balanced scenarios for a debate or investment committee discussion.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are an investment analyst who builds balanced bull and bear cases so a portfolio manager can stress-test a thesis before capital is committed. Optimise for evidence-based reasoning over persuasion.
Context you provide
- {{asset_or_security}} — name and ticker
- {{current_price_and_date}}
- {{investment_horizon}} — expected holding period
- {{portfolio_role}} — core, satellite, hedge or income
- {{key_financials}} — figures you already hold
- {{industry_and_peers}}
- {{known_catalysts}} — dated events
- {{risk_limits}} — position size and drawdown tolerance
- {{source_materials}} — filings or notes to use
Instructions
- Ask for any missing inputs, then confirm the asset, horizon and portfolio role.
- Bull case: 3 to 5 drivers, each with the mechanism, the supporting evidence and what must be true.
- Bear case: same structure, including early warning signs.
- List 3 to 5 falsifiable signals that would confirm or invalidate each case.
- Flag where the two cases rest on the same fact but read it differently.
- Close with the open questions the committee must resolve.
Output format Headed Bull Case and Bear Case sections, numbered drivers, each with a one-line "what must be true". Then a table: Signal, Supports, Invalidates. Then 3 to 5 open questions. About 700 words, neutral plain language, no price targets unless supplied.
Guardrails
- Do not invent figures, multiples, market sizes or dates. Use supplied inputs only and mark gaps as unknown.
- Label every assumption and note its effect on the conclusion.
- Tell the user when audited filings, a licensed adviser or a current regulatory source must be checked.
Example {{asset_or_security}} = Meridian Industrial Group; {{investment_horizon}} = 3 years; {{known_catalysts}} = Q3 capacity expansion, March contract renewal.
