Signal Engine for Public Trade Filings

There is a strong opportunity to move beyond a free dashboard and sell a decision-support product that converts public filing activity into ranked, testable investment signals. The clearest user pain is not just access to filings, but understanding which trades matter, how to rebalance on them, and whether any of it works historically.

Why this matters

You already know that filing data can hint at conviction, but the real problem starts after you open the dashboard. You are left guessing whether a cluster of buys matters, whether sells offset them, and how to turn noisy disclosures into a portfolio you can actually maintain. When you try to do this yourself, you end up stitching together leaderboards, spreadsheets, and rough heuristics with no proof that the method works. A useful product here would not just display trades. It would tell you what changed, why it matters, and how a rules-based strategy based on those events would have performed over time.

MVP Scope · 1–2 weeks

Week 1
  • Ingest and normalize Form 4 and 13F filings into a unified ticker-event table
  • Define three simple scoring rules for insider buys, fund accumulation, and political buys

Week 2
  • Launch a portfolio builder that selects top-ranked names based on user settings
  • Add net buy-sell trend charts and filer-type filters
  • Implement watchlists with daily alert emails for score changes
  • Publish three example strategies with transparent assumptions and caveats
  • Run a small paid conversion test from the waitlist into a 14-day trial

Differentiation

Our angle
The unmet need is not merely access to public disclosures, but trustworthy aggregation plus decision-ready analytics that convert noisy filings into usable investor workflows.

Why This Might Fail

Self-rebuttal — the most important trust signal

  1. 1The strongest objection is that delayed disclosures do not create enough tradable edge, so users may enjoy the data but refuse to keep paying.
  2. 2The product could be seen as financial entertainment if the scoring model is too simplistic or unstable across market regimes.
  3. 3Competitors can replicate basic aggregation and alerting quickly unless the backtests and ranking logic become materially better.

Evidence Summary

How AI synthesized this insight — no verbatim quotes

Several comments showed enthusiasm for the consolidated dataset, but the most valuable questions focused on usage rather than access. Around three to four commenters asked how to build a portfolio, how to interpret top-buy and top-sell panels, and whether adjacent analytics like sentiment help. At the same time, one commenter warned that delayed political trade disclosures may not be profitable. This points to a real business opportunity in signal interpretation and backtested workflows, not just raw data display.
