Finance prompt of the day

July 21, 2026 · for Investment banking, sales & trading, equity research, FP&A. One sharp, copy-paste prompt — free, every weekday.

You are a derivatives salesperson explaining an options structure to a client. The structure is [describe: e.g. call spread, risk reversal, collar, put spread] on [underlying], with [strikes/expiry if known]. Produce a plain-English walk-through:
1. What the structure IS and the view it expresses, in 2-3 sentences.
2. A payoff TABLE at key underlying levels (below lower strike, between, above) — using only strikes/premia I provide; where a premium is unknown, mark it "quote".
3. Max gain, max loss, and breakeven(s), each with the reasoning.
4. When this structure is the RIGHT tool vs a simpler alternative, and the main risks (path, vol, liquidity, assignment).
Do not quote a live premium or imply a price you were not given.

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 “Options-structure walk-through for a client”, step by step

The situation this prompt is built for: A client asked about a structure and you need a clear, honest explanation of the trade-offs. 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: a 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.

• [describe: e.g. call spread, risk reversal, collar, put spread] — this is the input the whole output quality hangs on. Each part narrows the answer: describe: e.g. call spread; risk reversal; collar; put spread. Demo fill: your own describe: e.g. call spread, risk reversal, collar, put spread — 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.
• [underlying] — this is the input the whole output quality hangs on. Demo fill: your own underlying — 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.
• [strikes/expiry if known] — this is the input the whole output quality hangs on. Each part narrows the answer: strikes; expiry if known. Demo fill: your own strikes/expiry if known — 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. What the structure IS and the view it expresses, in 2-3 sentences.
2. A payoff TABLE at key underlying levels (below lower strike, between, above) — using only strikes/premia I provide; where a premium is unknown, mark it "quote".
3. Max gain, max loss, and breakeven(s), each with the reasoning.
4. When this structure is the RIGHT tool vs a simpler alternative, and the main risks (path, vol, liquidity, assignment).

Why this structure works

Clients trust salespeople who explain trade-offs, not just upside; a payoff table plus honest max-loss/breakeven and a 'when NOT to use it' section is exactly the balanced framing that builds credibility.

On Pro, the explanation depth and the alternatives compared adapt to the client's sophistication and mandate from your profile (institutional vs private-wealth framing).

When to use it — and when not to

Reach for it when

• A client asked about a structure and you need a clear, honest explanation of the trade-offs.
• You can actually supply the inputs it asks for ([describe: e.g. call spread, risk reversal, collar, put spread] and 2 more) — 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 [describe: e.g. call spread, risk reversal, collar, put spread] 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.
