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.
Members of Congress reporting a position
2 members · estimate, as of Sep 10, 20262 members report a position (estimated). The largest estimated position is in the $100,001 - $250,000 band.
| Member | Party, chamber | Estimated position | Share of their portfolio |
|---|---|---|---|
| Gilbert Ray Cisneros, Jr. | Democrat · House | $100,001 - $250,000 | 0.5% |
| Tom Cole | Republican · House | $50,001 - $100,000 | 10.0% |
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.
