The trade is public. Making sense of it isn't.

Members of Congress are required to file two distinct types of financial disclosure documents. Confusing them is the first mistake most people make when they start trying to follow congressional trading.

The first is the Annual Financial Disclosure Statement. Filed once a year by May 15, it is a comprehensive snapshot of a member's entire financial life as of December 31 of the prior year: income, assets, liabilities, business interests, gifts, and securities holdings. Think of it as a net worth summary. It tells you what a member owned, not specifically when they bought or sold it.

The second, and the one most relevant to tracking trading activity, is the Periodic Transaction Report, commonly called a PTR. This is a STOCK Act requirement. When a member, their spouse, or a dependent child executes a securities transaction worth more than $1,000, a PTR must be filed within 45 days. It is a transaction-level record, not a portfolio snapshot. One PTR per batch of trades, with each individual transaction listed.

When you see news about a member of Congress buying NVIDIA or selling Pfizer, that information almost always comes from a PTR. The annual disclosure fills in the picture over time, but PTRs are the real-time (within 45 days) signal. The STOCK Act of 2012 created this system specifically to increase transparency around congressional trading. Whether it succeeds is a separate question.

The House and Senate maintain entirely separate filing systems. They operate under the same federal law but use different portals, different search interfaces, and different PDF formats. If you are trying to research a member and cannot find their filing, there is a good chance you are looking in the wrong chamber's system.

The most significant limitation of congressional disclosures is this: you never learn the actual size of a trade. The law requires members to report trades in standardized brackets. A trade reported as "$15,001 to $50,000" could be a $16,000 position or a $49,000 one. You cannot know.

This is not a bug in how the law was implemented. It is a feature of how the law was written. The brackets are part of the structural gaps that critics of the system have long pointed to. Without exact amounts, you cannot calculate precise gains, rank trades by conviction size, or determine whether a position was a meaningful part of someone's portfolio.

Under the STOCK Act, a PTR must be filed within 45 days of the transaction date. This sounds like a tight window. In practice, it means a member of Congress can trade on information obtained through their official duties, wait the full 45 days, and only then let the public know what happened. By that point, the stock may have moved significantly.

The trades that became cultural phenomena in 2021 and 2022 were never disclosed in real time. They became visible weeks after the fact, once the 45-day window had closed. By the time retail investors could react, the information advantage had largely played out.

There is also a secondary delay: many members file a few days before the deadline, not immediately after the transaction. And then there is the portal delay, the gap between when a filing is submitted and when it actually appears in the public search system. In total, the time between a trade occurring and a member of the public being able to see it can easily exceed two months.

The penalty for filing late is $200. The fine is waivable in "extraordinary circumstances" and is rarely enforced with any consequence. Multiple members have filed dozens or even hundreds of late PTRs with no meaningful penalty. The $200 threshold was set in 1978 and has never been adjusted for inflation. This is one of the core criticisms of the current system: the enforcement mechanism is too weak to create meaningful deterrence.

Reading a PTR carefully tells you what was traded, in which direction, by whom, and approximately how much. That is genuinely useful. But several categories of information are either omitted or obscured by design.

Mutual funds and ETFs are largely exempt. Under the Excepted Investment Fund (EIF) rule, publicly traded diversified funds do not require a PTR when bought or sold. A member can move millions of dollars in and out of broadly held index funds without triggering individual transaction reporting. This means that for members who hold the bulk of their portfolio in mutual funds rather than individual stocks, PTRs dramatically understate their actual trading activity.

Options and derivatives are coded, not described. A transaction coded as M (exercise of derivative security) or O (exercise of out-of-the-money derivative) tells you an option was exercised, but not its strike price, expiration date, or the full size of the underlying position. Options activity by members of Congress, particularly around earnings announcements or policy decisions, is an area that existing disclosure requirements handle poorly.

Sub-threshold trades are invisible. Any transaction under $1,000 requires no disclosure. A member could hold a small position in dozens of stocks simultaneously without any of them appearing in their PTRs, as long as each trade stays below the threshold.

Context is absent. A raw PTR tells you nothing about the legislative calendar, the member's committee assignments, or whether a classified briefing occurred in the preceding week. It is a transaction record, not an intelligence document. The context has to be added from outside the disclosure system entirely.

The tools that aggregate congressional disclosures, and there are several good ones, all face the same fundamental constraint: they can only show you what the disclosure system surfaces. Ticker, direction, amount bracket, date. That is the full extent of what a PTR contains.

What a raw PTR cannot tell you is whether a trade matters. A $50,000 purchase of a defense contractor by a member of the Senate Armed Services Committee, placed three days before a closed-door hearing on the Pentagon's budget request, is very different from the same trade by a member of the Senate Agriculture Committee who has no oversight role. The PTR looks identical. The context that makes one worth examining and the other unremarkable has to come from somewhere else.

For anyone trying to identify the trades that reflect genuine information advantages rather than ordinary portfolio activity, the disclosure system is the starting point, not the finish line. Looking at who files the most transactions is a reasonable place to begin. But volume alone is not the signal. The member who files 300 trades a year through a diversified advisor-managed portfolio is not necessarily more interesting than the one who files 12 trades a year, all of them in sectors directly tied to their committee work.

This is what curation adds. Not just aggregation of the raw PTR data, but the work of asking whether a specific trade, from this specific member, at this specific moment in the legislative calendar, is something that the public record gives you a reason to notice.
