This is the public record of stock transactions Markwayne Mullin has reported under the STOCK Act, which requires members of Congress to disclose trades by themselves, a spouse or a dependent child. It is a record of what has been filed, not a portfolio: the law allows up to 45 days to report, amounts are disclosed as brackets rather than exact figures, and many of these trades are executed by advisers or in managed accounts. Nothing here is investment advice.
Each purchase measured over the 12 months following its disclosed transaction date, against SPY over that same window. Equal-weighted, one count per purchase.

How many stock trades has Markwayne Mullin disclosed?
Markwayne Mullin has disclosed 467 stock transactions in the public STOCK Act record we track, running from Jan 3, 2023 to Feb 25, 2026. That is 304 purchases and 163 sales. Each one is a periodic transaction report filed with the Senate Office of Public Records.
Which stocks does Markwayne Mullin trade most often?
The most frequently traded positions on Markwayne Mullin's disclosures are GS (10 trades), LRN (8 trades), ADBE (8 trades), AMAT (7 trades), ZTS (7 trades). Frequency is not size: the filings report dollar ranges rather than exact amounts, so a single large trade can matter more than several small ones.
Have Markwayne Mullin's stock picks beaten the market?
Across the 188 stock purchases Markwayne Mullin has disclosed that we can price, the median position returned +25.4% over the 12 months following the disclosed transaction date, against +27.0% for SPY over the same windows. That is a median difference of -2.8%, and 89 of the 188 purchases (47%) beat the index. These are not the member's actual returns: disclosures give a dollar bracket and no share count, so each purchase is counted once and weighted equally, and any later sale is not matched back to the buy.
How is Markwayne Mullin's trade performance calculated?
Each disclosed purchase is measured over a fixed 12-month window, from the close on the first trading day on or after the reported transaction date to the close 12 months later, using split- and dividend-adjusted prices. The same window is applied to SPY and the difference is the excess return. A fixed window is used so that trades from different years are comparable: measuring every purchase up to today instead would score a 2014 buy against a decade of index compounding and a recent buy against a few months. Purchases from the last 12 months are excluded because their window has not closed, and 7 more could not be priced because the ticker no longer trades. Sales, options, bonds and municipal securities are not included. Figures update daily.
Are these Markwayne Mullin's own trades?
Not all of them. Of the 467 transactions on record, 35 are marked as the spouse's and 354 as jointly held. Members must disclose trades made by a spouse or dependent child, and many are executed by financial advisers or in managed accounts, so a disclosure is not evidence that the member personally chose the stock.
How current is this record?
The STOCK Act gives members up to 45 days to report a trade, so the newest transaction here (Feb 25, 2026) was disclosed on Mar 10, 2026 and more recent trades may exist that have not been filed yet. This page is a record of what has been disclosed, not a statement of what Markwayne Mullin currently holds.
Do the dollar figures show how much was actually traded?
No. Congressional disclosures report each trade as a bracket, such as $1,001 to $15,000, rather than an exact amount. The largest bracket on this record is $500,001 - $1,000,000. Adding brackets together produces a made-up number, so we do not publish a portfolio total.
Source: periodic transaction reports filed with the Clerk of the House and the Senate Office of Public Records, the same public documents linked in the Filing column. Disclosures are reported with up to a 45-day delay and amounts are brackets, not exact figures. Past performance does not predict future results, and none of this is investment advice.
