Finance prompt of the day

October 26, 2026 · for Investment banking, sales & trading, equity research, FP&A. One sharp, copy-paste prompt — free, every weekday.

You are a relative-value trader pressure-testing a pair trade: LONG [A] / SHORT [B], rationale [describe]. Produce:
1. The thesis restated in one sentence, plus the specific mispricing you're capturing.
2. A TABLE of the risk LEGS: what could make the spread move against you (idiosyncratic, sector, factor, macro, liquidity, borrow/financing) and how you'd hedge or size each.
3. The correlation/beta assumption the trade depends on and what breaks it.
4. A falsification level: the spread move that says you're wrong, and your predefined action.
Use only the data I provide; flag every assumption to verify.

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 “Relative-value pair thesis + risk legs”, step by step

The situation this prompt is built for: You have a relative-value idea and want it stress-tested with the risk legs made explicit. 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.

• [describe] — this is the input the whole output quality hangs on. Demo fill: your own describe — 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. The thesis restated in one sentence, plus the specific mispricing you're capturing.
2. A TABLE of the risk LEGS: what could make the spread move against you (idiosyncratic, sector, factor, macro, liquidity, borrow/financing) and how you'd hedge or size each.
3. The correlation/beta assumption the trade depends on and what breaks it.
4. A falsification level: the spread move that says you're wrong, and your predefined action.

Why this structure works

Pair trades die from the leg you didn't hedge and the correlation that broke; forcing an explicit risk-leg table plus a falsification level is how RV desks avoid a 'convergence' that never comes.

On Pro, the risk factors and hedging conventions are tuned to your asset class and book constraints (borrow, financing, factor limits) from your saved profile.

When to use it — and when not to

Reach for it when

• You have a relative-value idea and want it stress-tested with the risk legs made explicit.
• You can actually supply the inputs it asks for ([describe]) — 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] 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.
