Every trade Markwayne Mullin has disclosed

Republican U.S. senator from Oklahoma

Holds no standing committee assignment.

Updated Mar 10, 2026 · Members have up to 45 days to report a trade, so the newest transactions may not be filed yet. · Congressional trading statistics

This is a record of what Markwayne Mullin has filed, not a portfolio: amounts are disclosed as brackets rather than exact figures, and many of these trades are made by advisers or in managed accounts. Nothing here is investment advice.

Markwayne Mullin holds no standing committee assignment in the current Congress, so none of these trades can be matched against a committee jurisdiction. Members in party leadership and former Speakers commonly serve on no standing committee. How committee overlap is measured for everyone else is on our congressional trading statistics page.

What is in the record

Congressional filings report a single stream of transactions. These are the asset classes it actually contains, which is what decides whether a performance figure can be computed at all.

Only listed stocks and ETFs can be priced against an index. Bonds, municipal securities and structured notes are excluded from every return figure on this page.

How the disclosed purchases performed

Among 188 priceable purchases with a completed 12-month window, across 96 securities, the median return was +25.4%, versus +27.0% for SPY. That is 188 of the 304 purchases on this record. Each is measured over the 12 months after its transaction date, equal-weighted, one count per purchase. Every ranked member on one page: the Congress vs S&P 500 scorecard.

What this is not. These are not Markwayne Mullin's returns. Disclosures report a dollar bracket and never a share count, so positions cannot be weighted and every purchase here counts once and equally. Sales are not matched back to the buys that opened them, so a position may well have been sold long ago; this measures how the stock moved in the year after the disclosed purchase date, nothing more. 9 of the 188 purchases are disclosed as a spouse's or dependent's rather than the member's own. Purchases from the last 12 months are excluded because their window has not closed yet. The 188 scored purchases cover 96 securities, so repeat buys of the same holding are counted separately and this is not 188 independent decisions. A further 7 purchases are not counted because the ticker no longer trades or could not be priced.

Questions about this record

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.
