Finance prompt of the day

September 7, 2026 · for Investment banking, sales & trading, equity research, FP&A. One sharp, copy-paste prompt — free, every weekday.

You are a buy-side analyst writing a ONE-PAGE idea write-up for [TICKER]. I will give the thesis and numbers. Produce a structured one-pager with EXACTLY these blocks:
1. RECOMMENDATION (long/short, sizing view, target/return) — one line.
2. THESIS in 3 bullets (why this, why now).
3. VARIANT VIEW — where you differ from consensus and why you're right.
4. KEY NUMBERS — a small TABLE of the metrics that matter (use only figures I provide; mark gaps "TBD").
5. RISKS & KILL CRITERIA — what would make you wrong.
6. THE ONE QUESTION that would most change your conviction.
Keep it to a page. Do not fabricate figures or a target you can't support.

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.

What changed for Finance

How to run “One-page investment idea write-up”, step by step

The situation this prompt is built for: You want to pitch an idea to your fund/PM in a tight one-pager that leads with the decision. 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.

• [TICKER] — this is the input the whole output quality hangs on. Demo fill: your own ticker — 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. RECOMMENDATION (long/short, sizing view, target/return) — one line.
2. THESIS in 3 bullets (why this, why now).
3. VARIANT VIEW — where you differ from consensus and why you're right.
4. KEY NUMBERS — a small TABLE of the metrics that matter (use only figures I provide; mark gaps "TBD").
5. RISKS & KILL CRITERIA — what would make you wrong.
6. THE ONE QUESTION that would most change your conviction.

Why this structure works

A one-pager forces the discipline of leading with the call and the variant view; the fixed block structure plus kill criteria is exactly what a PM needs to make a decision fast.

On Pro, the block emphasis and return framing match your fund's style and IC format from your profile, so the write-up drops straight into your process.

When to use it — and when not to

Reach for it when

• You want to pitch an idea to your fund/PM in a tight one-pager that leads with the decision.
• You can actually supply the inputs it asks for ([TICKER]) — 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.

Adapting today’s prompt for adjacent roles

“One-page investment idea write-up” sits in the Pitch & Presentation lane of the finance pool. If your seat is one desk over, these are the same craft-move rebuilt for the neighbouring workflow — pulled from the same curated pool, each free in full at its permalink:

You are an IB associate building a football-field valuation summary for [TARGET]. I will paste the ranges from each method (DCF, trading comps, precedent transactions,…

You are a sales-trader drafting a client email. Context: [what you want to communicate — an axe, a flow observation, a level, a piece of color]. Produce: 1. A subject…

You are an analyst scoring the management team of [COMPANY]. I will give the history/facts (M&A, buybacks, dividends, capex, debt, comp structure, insider ownership,…

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 [TICKER] 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.
