Which stocks do members of Congress trade most?

How were the trades counted?

The figures on this page come from OQRO's copy of the periodic transaction reports that members of the House and Senate filed from January 2021 onward, as published by the Clerk of the House and the Senate's electronic disclosure site. Each line of a report that names a stock OQRO matched to a US-listed company counts as one trade. Lines held for review, mostly assets whose company could not be matched with confidence, are left out, and so are reports filed on paper and scanned. The counts were computed on 29 October 2026, so reports filed after that day are not in them. A report filed late can cover a trade made years before, which is why the totals since 2021 include a few older trades.

Which companies appear most since 2021?

Microsoft comes first, with 589 trades, and five large technology companies take the first five places. Apple is the company traded by the most members: 84 different filers reported at least one Apple trade, one more than for Microsoft. The table lists the ten companies with the most report lines.

Purchases and sales do not always add up to the total, because a few lines are exchanges. Members are counted by who filed, so a trade in a spouse's account is counted under the member who reported it.

Which companies came first in 2025?

For trades made in 2025, NVIDIA moves to first place with 130 trades, 93 of them purchases. Microsoft and Apple were each traded by 35 members, the most among these ten, and UnitedHealth, Meta, Broadcom, Tesla and Visa complete the list.

Why do a few companies fill the top of the list?

Part of the answer is in how the reports work. Every transaction is a separate line, so a member who trades often, or whose account is traded by an adviser, adds many lines across many companies. Microsoft's 589 lines come from 83 members, about seven each; PayPal's 166 come from 34, about five each. The count therefore measures how often a company appears in the reports, not how many members chose it or how much money moved. The reports themselves do not say who decided a trade or why it was made.

Do members buy or sell these stocks more often?

It differs by company. Since 2021, sales outnumber purchases for Microsoft, Apple, Alphabet and PayPal, and purchases outnumber sales for NVIDIA, Amazon, Johnson & Johnson, Berkshire Hathaway, Home Depot and JPMorgan Chase. For trades made in 2025, purchases led for NVIDIA (93 against 37) and Amazon (71 against 22), and sales led for Microsoft, Apple and UnitedHealth. Across all the lines OQRO holds for trades made in 2025, House members reported 3,698 purchases and 4,034 sales, and senators 668 purchases and 454 sales, as shown in OQRO's yearly Congress figures.

What this does not tell you

The counts are report lines, not dollars. A trade reported in the $1,001-$15,000 category counts as much as one in the $1,000,001-$5,000,000 category, and the reports give only those ranges (what the ranges mean). They include trades in a spouse's or a dependent child's account, which the report form asks members to disclose. A long list of trades in one company is not evidence that anyone knew something in advance: a periodic transaction report is a disclosure, not an allegation. Nor does a ranking say whether following these trades would have paid, since the STOCK Act allows up to 45 days before a trade is reported, and the typical trade made in 2025 was filed 28 days after it was made. Matching a report's asset to a company is OQRO's own work and can be wrong when a report describes the asset loosely, so check any line against the filing, which OQRO links from every row on its politician trades page.
