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 marked GAAP compares a GAAP figure the company reported with an adjusted consensus, two different measures, so a one-time gain or charge can move it either way; basis unverified means we could not classify the reported figure. A flag reads n/a only when a number is missing. An estimate is a forecast made by analysts, not a company target.

Since the trade: the stock's move from the trade date to the latest close we hold, as of Sep 10, 2026, an estimate, with the S&P 500 over the same window and the difference against it. The figures describe the stock after the trade, not the member's result: the filing carries a band, not a fill, and a sale keeps the same sign, so a positive figure after a sale means the stock kept rising. An option row carries the underlying stock's move. A row marked n/a has no market price. Not investment advice.

Estimate, as of Sep 10, 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.

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.
