How We Read a Disclosure

Last updated: June 12, 2026 · by The Potomac Ledger

Every figure we publish comes from a public filing that an official was legally required to make. This page explains exactly how we turn those filings into the weekly editions — what we use, what we add, and the limits we never paper over.

The data we use

We work only from official, public records. Nothing here is leaked, scraped from a brokerage, or inferred from market activity.

Trades held by a spouse or dependent children are part of the same filings and are included as the filing reports them. Each entry links back to the original document so you can read the source yourself.

Disclosure date is not the trade date

This is the single most common misreading, so we are strict about it. Filings lag the actual trade by 30 to 45 days, which means a disclosure that appears this week usually reflects a trade made weeks earlier. We always say a trade was disclosed in a given week — never executed that week. Where both dates exist in the filing, we keep them distinct.

"Disclosed this week" and "traded this week" are different claims. We only make the first one.

Why every figure is a range

The law requires officials to report transaction values in broad bands — for example, "$1,001–$15,000" or "$500,001–$1,000,000" — not exact amounts. So every dollar figure you see is a disclosed range, not a precise number. When a single large figure gets quoted elsewhere, it is almost always the top of a range.

What a "conflict" flag means

A conflict flag is a heuristic, not an allegation. We raise it when the company traded falls in a sector that overlaps the official's role — a lawmaker trading a company in their committee's jurisdiction, or an agency official trading a company their agency oversees. It is a "potential overlap worth a second look," and nothing more.

Screening compares each trade only to the sectors a member's current committees oversee, so an official with no current committee seat — a departed member or chamber leadership — has nothing to screen against. For them we show "—" rather than a count: the absence of flags is "not screened," not an all-clear.

A flag is a reason to pay attention, not a finding of insider trading or wrongdoing. Disclosure is legal; the overlap is context, not an accusation.

What "late" means

The STOCK Act sets a filing deadline of 30 to 45 days after a trade. When a disclosure lands after that window, we mark it late and show the number of days. Late filings are common and a late mark is a factual statement about timing — it says the paperwork arrived past the deadline, not that anything improper happened.

How we decide what's "notable"

The free editions and the homepage tracker surface a notable subset: sizeable transactions, flagged sector/committee overlaps, and late filings, shown one row per official so a single prolific filer can't crowd out everyone else. Members see every disclosed trade in full. The selection is mechanical and applied the same way to every official, regardless of party.

Corrections

If a filing is amended or we get something wrong, we fix it. The underlying records are public, and we link to them on every entry so any reader can check our work against the source.
