No disclosures of that kind among the 20 rows shown.
Showing the 20 most recent disclosures. One row is one disclosure: a member filing for more than one account on the same day, in the same band, is counted once and marked.
This is a closed record: it covers the disclosures from Markwayne Mullin's service, which ended on Mar 23, 2026. Only a late filing for a trade made in office would add to it.
Since the trade: the stock's move from the trade date to the latest close we hold, as of Sep 10, 2026, with the S&P 500 over the same window and the difference against it. The numbers describe the stock after the trade, not the filer's result: a disclosure carries a band, not a fill, and a sale keeps the same sign, so a positive number after a sale means the stock kept rising. An option row carries the underlying stock's move. Estimates; n/a on assets with no market price. Not investment advice.

Year by year
buy volume against sale volume · range midpoints- Bought
- Sold
Disclosed volume per year the member traded, 2017 to 2026. 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.

Questions
How many stock trades did Markwayne Mullin disclose?

How long did Markwayne Mullin take to report a trade?

In the disclosures shown here the most frequent tickers are MCK, ADBE, AIT, AMKR, APG.
Which accounts do Markwayne Mullin's disclosures name?
Of the 20 disclosures shown, 20 name a joint account. The account is whatever the filer wrote on the disclosure; a spouse's or a joint account is disclosed under the filer's name, as the STOCK Act requires.
Where does the estimated net worth on this page come from?
It is an estimate produced by a model, not a figure the filer disclosed. Congressional financial disclosure reports every asset and liability in a band rather than an amount, so the model takes a value within each band and nets the liabilities, and it carries the stock holdings it tracks at the latest price we hold, which is why the estimate can move on a day when nothing was filed. It is shown to two figures because the largest band is open ended and a third would be arithmetic rather than information. It covers only what the disclosures carry, and it is not a measurement of anyone's wealth. The methodology page sets out how it is built and what it leaves out.
How have the stocks moved since Markwayne Mullin's trades?
Across the 20 priced rows shown, the median stock move from the trade date to the latest close we hold (Sep 10, 2026) is +12.3%. That figure is an estimate describing the stock after each trade, not the filer'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.
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.
