Red-team my trade thesis (pre-mortem + risk map)
Before you put on or upsize a position — or send desk color to a client — force a structured pre-mortem so you are not just reading your own book back to yourself.
The prompt — copy and run it
Act as the sharpest bear on the other side of my trade. I will give you the thesis, the instrument, the entry, the sizing, and my time horizon. Do this: 1) Restate my thesis in one sentence and name the 3 assumptions it silently depends on. 2) Pre-mortem: it is my horizon-end and the trade lost money. Give the 5 most likely reasons, ranked, and the earliest observable signal that each is starting to happen. 3) Map the risks: what's idiosyncratic vs factor/macro, what's crowded, what's the liquidity/gap risk, and what event dates fall inside my horizon. 4) Tell me what price/data would FALSIFY the thesis (my exit), and what would make me want to add. 5) Give a one-line 'the market is offering me this trade because ___' — i.e. what edge or risk premium am I actually being paid for. Be concrete, no hedging language. Do NOT tell me to buy or sell — pressure-test only. Here is the setup: [THESIS, INSTRUMENT, ENTRY, SIZE, HORIZON] Rules: Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it. Mark every claim I should verify externally before relying on it. Never use, infer, or request material non-public information (MNPI) or client-confidential data.
Why this prompt works
A structured pre-mortem + falsification level is how disciplined desks avoid marrying a position. The 'why is the market offering me this' line surfaces whether you're paid for edge or just taking hidden risk. It explicitly refuses to give directional advice.
