Actual against the consensus estimate at the time. A flag marks a beat or a miss of more than 1.5% either way; inside that band the quarter is in line. A flag reads n/a only when a number is missing. An estimate is a forecast made by analysts, not a company target.

One row is one filing, newest filing first. A filing that reported its trade in several tranches is summed, priced at the weighted average, and marked with its line count. The delay counts business days from the trade to the filing, the unit of Form 4's two business day deadline: weekends and federal holidays are skipped. How the filing itself works is explained in our guide to Form 4.

Since the trade is an estimate, set beside the S&P 500 over the same window, with the gap between the two in percentage points. The filing carries a band, not a fill, and a sale keeps the stock's sign, so a positive figure after a sale means the stock kept rising after it. An option row carries the underlying stock's move. A row marked n/a is one we hold no figure for.
A delay above 45 days is the gap between the dates on the report; we mark a filing late only after checking it.
"Not captured" means the band or the transaction type on the original report is missing from our data.
"Dates conflict" marks a row whose disclosure is dated before its trade on the record we hold. Both dates are printed as filed, and no since-the-trade figure is computed from them.

Members of Congress reporting a position
5 members · estimate, as of Oct 23, 20265 members report a position (estimated). The largest estimated position is in the $100,001 - $250,000 band.

Estimate, as of Oct 23, 2026. Each position is modelled from the member's disclosed transactions and annual filings: the midpoint of each disclosed band, moved with the stock's price since the trade. It is a rough estimate of a reported position, not a figure from a filing, which is why it is shown as a band. Share of portfolio sets that estimate against the member's whole estimated public-stock portfolio.

How to read a Form 4
A DECISION THE INSIDER MADE
COMPENSATION PLUMBING
Congress rows disclose a value range rather than an exact amount, and the STOCK Act allows up to 45 days to report. Full sourcing and the limits of this data are on the methodology page. A filing is a record of a transaction, not a signal, and nothing here is investment advice.
