CapitolRadar analysis
68 disclosures lean toward purchases
MMC — Marsh & McLennan Companies, Inc., in Financial Services / Insurance - Brokers — recorded 68 tracked congressional trades from March 31, 2020 through September 29, 2025. Purchases represented 46 trades, compared with 22 sales, or about 68% of the total. The activity came from only five distinct traders, so the directional split reflects a small group rather than broad congressional participation.
The named buyers account for all 46 purchases. Ro Khanna made 27 buys, approximately 59% of the purchase count, with the latest dated September 29, 2025. Kevin Hern and Lois Frankel each made eight buys; their latest purchases were February 15, 2024 and June 10, 2020, respectively. Tommy Tuberville made two buys, most recently on October 17, 2023, while Diana Harshbarger made one, dated January 28, 2022. The concentration in one buyer limits how widely the positive trade balance can be generalized.
19 buys across eight reported quarters
The eight quarters provided contain 37 trades and 19 buys. The strongest purchase shares in this set were 2024 Q1, with four buys in five trades, and 2025 Q3, with three buys in four trades. By contrast, 2022 Q4 had four trades and no buys. Activity was evenly divided in 2023 Q2, Q3 and Q4, while 2023 Q1 contained one buy among four trades. These are small quarterly samples, ranging from four to six transactions, and the supplied quarter list is not continuous enough to characterize every period in the full date range.
Six overlap tickers, each tied to one buyer
Among these MMC buyers, one also bought each of AME, BK, CHTR, CVS, FDS and HUBB. Because every overlap involves only one buyer, the data do not establish a shared cross-stock pattern across the group.
Congressional disclosures can appear up to 45 days after a transaction, so reported activity is not real-time. Any disclosed transaction amount ranges are estimates rather than exact trade values. The five-trader sample and the smaller quarterly and overlap samples warrant particular caution when interpreting the counts.
