Finance prompt of the day

October 28, 2026 · for Investment banking, sales & trading, equity research, FP&A. One sharp, copy-paste prompt — free, every weekday.

You are a skeptical IC member RED-TEAMING my investment memo draft below. Produce:
1. A BLUF check: is the recommendation and the core reasoning in the first paragraph? If it's buried, rewrite the opening to lead with the proposition.
2. An ARGUMENT-INTEGRITY pass: where is a claim unsupported, where does evidence not match the conclusion, and where is a key risk under-weighted or missing. Be specific and quote the line.
3. The 5 HARDEST questions the committee will ask that the memo does not yet answer.
4. A TIGHTENING list: sections that can be cut or compressed without losing the argument.
Do not add facts or figures I did not provide — flag gaps instead.
[PASTE MEMO DRAFT]

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.

How to run “IC-memo red-team & tightening of an existing draft”, step by step

The situation this prompt is built for: You have a full IC/investment memo draft and want it red-teamed and tightened before it goes to the committee. Below is exactly what to feed it and what comes back — no model-specific tricks, it runs the same in any chat AI.

What each placeholder does

Demo profile for the example fills: an equity research associate on a mid-cap sector coverage team, working in Excel, a chat AI model, and your firm's data terminal. Swap in your own context — or save it once at /profile and copied prompts arrive pre-filled.

• [PASTE MEMO DRAFT] — this is the input the whole output quality hangs on. Demo fill: your own paste memo draft — one or two concrete lines beats a paragraph of vague context. Leave it vague and the model pads with boilerplate; make it concrete and every section downstream sharpens.

What the model hands back

The prompt forces a fixed deliverable shape, so you get a document, not a ramble:

1. A BLUF check: is the recommendation and the core reasoning in the first paragraph? If it's buried, rewrite the opening to lead with the proposition.
2. An ARGUMENT-INTEGRITY pass: where is a claim unsupported, where does evidence not match the conclusion, and where is a key risk under-weighted or missing. Be specific and quote the line.
3. The 5 HARDEST questions the committee will ask that the memo does not yet answer.
4. A TIGHTENING list: sections that can be cut or compressed without losing the argument.

Why this structure works

Memos get rejected on the buried lede and the unaddressed risk; a red-team that forces the proposition up front, checks argument integrity, and pre-empts the committee's hardest questions is exactly the review that gets a memo approved.

On Pro, the red-team lens arrives set to your IC's known hot buttons and memo format from the profile you set once.

When to use it — and when not to

Reach for it when

• You have a full IC/investment memo draft and want it red-teamed and tightened before it goes to the committee.
• You can actually supply the inputs it asks for ([PASTE MEMO DRAFT]) — this prompt is an amplifier for real context, not a substitute for it.
• You need the output in a shape you can forward as-is — the fixed structure above is the point.

Skip it when

• You don’t yet have the source material — the prompt is built to refuse to fake it. Its own guardrail: “Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it.” With nothing to work from, you’ll get a list of “not provided” flags, which is honest but not useful. Collect the inputs first.
• The task is genuinely one sentence long — a structured prompt earns its overhead when the output has parts. For quick one-off questions, just ask.

Common failure modes (and the fixes)

• Failure: letting the model drift past the prompt’s own guardrail — “Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: letting the model drift past the prompt’s own guardrail — “Mark every claim I should verify externally before relying on it.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: letting the model drift past the prompt’s own guardrail — “Never use, infer, or request material non-public information (MNPI) or client-confidential data.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: filling [PASTE MEMO DRAFT] with a vague summary. The output can only be as specific as this input — generic context in, generic deliverable out. Fix: paste raw specifics (real names, real numbers, real constraints), then trim the model’s output, not your input.
• Failure: accepting the first pass. Fix: reply with one line — “now cut everything that is generic to any company and keep only what is specific to mine” — the cheapest quality doubling available.
