A SEC filing research prompt pack for source-aware stock research

A developer has created a prompt pack for source-aware stock research that requires AI models to cite specific SEC filings, dates, and exact excerpts for every claim. The workflow enforces a non-negotiable rule that answers must include source type, publication date, exact text, confidence level, and what remains unknown, with a built-in checklist of red flags that force human review. The project, called Tomorrow Terminal, aims to combine filings, financials, market data, and crowd discussion into a single company profile without allowing AI to invent confidence or make predictions.

Who this is for

Use this when you want to understand a company from primary sources without letting an AI model invent confidence. The goal is not to decide whether a stock is good or bad. The goal is to build a cleaner research trail from SEC filings, financial statements, market data, news, and crowd discussion.

#

Non-negotiable rule

Every answer must include:

  • Source type, for example 10-K, 10-Q, 8-K, S-1, earnings release, transcript, news article, or company page
  • Filing or publication date
  • Exact excerpt or table row used
  • A short explanation of why it matters
  • Confidence level
  • What is still unknown

If the model cannot cite the source, it should say so and stop.

#

10 minute first-pass workflow

Identify the business

  • Read the company description, segment note, and latest risk factors.

  • Output a one-paragraph plain-English business model.

Find what changed

  • Compare the latest 10-Q or 10-K against the prior period.

  • Focus on revenue, gross margin, cash flow, debt, customer concentration, and share count.

Check liquidity and dilution risk

  • Pull cash, debt, operating cash flow, recent financing, shelf registrations, warrants, and ATM programs.

Read management's own warnings

  • Extract the 5 to 10 risk factors most directly tied to revenue, survival, regulation, or financing.

Separate facts from narrative

  • Create two columns: verified facts and management claims.

Inspect market and crowd context

  • Summarize recent news, Reddit, and StockTwits discussion as attention context only.

  • Do not treat crowd excitement as evidence of business quality.

Write the research memo

  • Summarize what is known, what changed, what could matter next, and what needs human review.

#

Prompt 1: source-grounded company snapshot

#

Prompt 2: compare this filing to the prior one

#

Prompt 3: risk factor triage

#

Prompt 4: liquidity and dilution checklist

#

Prompt 5: management claim audit

#

Prompt 6: crowd discussion sanity check

#

Prompt 7: final research memo template

#

Red flags that should force a human review

  • The model cites a filing but cannot quote the excerpt
  • The model mixes quarterly and annual numbers without labeling them
  • The model treats adjusted EBITDA as cash flow
  • The model ignores share count changes
  • The model makes a recommendation from social sentiment
  • The model summarizes a risk factor without checking whether it changed
  • The model uses news as proof when the primary filing says something narrower

#

Clean output checklist

Before sharing a research note, verify:

  • Every major claim has a source
  • Dates are visible
  • Excerpts are short and exact
  • Unknowns are listed instead of guessed
  • Crowd chatter is clearly labeled as chatter
  • The conclusion does not become financial advice

Why I made this

I have been working on Tomorrow Terminal, a source-aware stock research workflow that combines filings, financials, market data, news, Reddit, and StockTwits into one company profile. This prompt pack is the manual version of the standard I want AI research tools to meet: useful summaries, visible evidence, and no magic predictions.

Research only. Not financial advice.
