No disclosures of that kind among the 20 rows shown.
Showing the 20 most recent disclosures. Lines for the same asset, day, band and action are shown once and marked with the number of lines. All of Brian J. Mast's trades in the browser, every line of every report.
"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.
Under each figure: the S&P 500 over the same window, and the gap between the stock and the index in percentage points. A disclosure carries a band, not a fill. After a sale the stock's move keeps its sign, so a positive number means the stock kept rising after the sale. An option row carries the underlying stock's move, not the option's value. Where a ticker stopped trading the row says when its price history ends; where the company trades on under a new ticker the figure is priced under that one. Estimates; n/a where we hold no figure for the row.

Disclosed volume per year the member traded, 2017 to 2024. A filing gives a range, not an amount, so each bar sums the midpoints of the ranges disclosed that year: a $1,001 to $15,000 line counts as $8,000. The sale side also counts exchanges, including shares received in a spin-off or merger.

Questions
How many stock trades has Brian J. Mast disclosed?

Which tickers does Brian J. Mast trade most?

Which accounts do Brian J. Mast's disclosures name?
Of the 20 disclosures shown, 3 name a dependent child's account. 17 do not name an account. The account is whatever the filer wrote on the disclosure; a spouse's or a joint account is disclosed under the member's name, as the STOCK Act requires.
Where does the estimated net worth on this page come from?
A model's estimate, not a figure the member filed. Reports give every asset and debt as a range, so the model takes a value inside each range and subtracts debts. We round it because the top range has no upper limit. It covers only what the reports carry and is not a measure of anyone's wealth. The methodology page sets out how it is built and what it leaves out.
How have the stocks moved since Brian J. Mast's trades?
Across the 17 priced rows shown, the median stock move from the trade date to the latest close we hold (figures as of Oct 26, 2026) is -94.5%. 1 row whose price history ends earlier is left out of it. That figure is an estimate describing the stock after each trade, not the member's result: a disclosure carries a band, not a fill, a sale keeps the same sign, and an option row carries the underlying stock's move. 2 of the rows shown have no figure in our data.
How to read a STOCK Act filing
WHAT THE FILING ACTUALLY SAYS
A disclosure is a record of a transaction, not evidence of anything else, and nothing here is investment advice. Sourcing and the limits of this data are on the methodology page. How these reports work is explained in our guide to STOCK Act reports.
