Following Congressional Stock Trades Using Public Data

Following Congressional Stock Trades Using Public Data

There is a category of market data that most retail investors never think to check: their own government publishes it, for free, by law.

Members of Congress are required to disclose personal financial transactions under the STOCK Act — the Stop Trading on Congressional Knowledge Act. The disclosures land in a public database anyone can open. The data is not leaked, not scraped from somewhere shady, and not a rumor. It is the official record, and it has been public by law for well over a decade.

If you have ever wanted to follow that record rather than read someone's screenshot of it, here is how to do it properly.

What the record actually contains

A congressional disclosure tells you the filer, the asset, the transaction type (purchase, sale, or exchange), an amount range in bands rather than an exact figure, and two dates: the transaction date and the disclosure date.

Two honest caveats before you go further. First, the amount is a range — the form is designed that way, and exact position sizes are never public. Anyone who tells you a member bought "exactly $1.2 million of X" is interpolating. Second, the disclosure window is measured in weeks, not minutes. Filers report periodically, and late filings happen. This is a lagging public record, and treating it as a real-time signal is a category error.

That is precisely why the useful framing is "follow the public record" — not "insiders are cheating." Nothing about this data says the law doesn't apply to anyone. It says the law requires publication, and the publication is what you're reading.

The DIY path

The mechanical version is straightforward: open the official disclosure portal, search by member name, read each filing. This works. It is also slow, and it answers questions in the wrong order — it is organized by filer, when the question you actually have is almost always about a ticker.

"Did anyone disclose a transaction in this semiconductor name last quarter?" is a per-ticker question. Doing that by hand means opening dozens of filings per name, per quarter, and hand-matching the asset description — which arrives as free text, sometimes vague.

What per-ticker tracking adds

This is the gap Catalyst Terminal at MarketPicks.ai — https://marketpicks.ai/politician-tracker was built to close. Its Congress tracker indexes the public disclosures and lets you look them up by ticker, the way a normal investor thinks about a portfolio:

• Per-ticker matching. Type a symbol, see the disclosed transactions in that name — member, type, amount range, dates. • Receipts on every row. Each trade links back to the underlying disclosure, so you can verify the row against the official filing yourself instead of trusting the table. • Freshness made visible. Every view is dated. You see the newest filing in the set, so the lag is a fact on the screen rather than a surprise. • Explainers where the confusion lives. Tooltips on the transaction type and the amount range explain what the filing form does and does not tell you — the 45-day periodic reporting rule, and why a range is a range.

The tracker covers thousands of disclosed transactions across more than a hundred members, updated as new filings land.

How to actually use it (without kidding yourself)

Treat congressional disclosures the way you would treat any other slow-moving ownership data: as one input, never a trigger. A few disciplines that hold up:

1. Check the date on everything. Transaction date and disclosure date are different facts, and the gap is where the misreading happens. 2. Never infer size. Ranges are ranges. 3. Corroborate. One disclosed sale of a stock you like is noise. A pattern across members and across months is at least worth understanding. 4. Remember it's one-sided. You see what was disclosed, not the thesis, not the hedge, not the rest of the portfolio.

Catalyst Terminal applies the same receipts-first rule to everything it renders — the company autopsies cite the SEC filing behind each claim, and the movement desk tells you what's driving a price rather than just that it moved. That consistency is the point: the tool's job is to make the public record legible, not to make it dramatic.
