Several U.S. lawmakers have dramatically increased their stock trading over the past 90 days, according to periodic transaction reports filed under the STOCK Act. Rep. Ed Case (D-HI) recorded a velocity z-score of 7.19, completing 14 trades against a typical monthly baseline of just 0.21. Sen. Mark Warner (D-VA) posted a 6.87 z-score with 43 trades in the period, compared to his 1.28 monthly average. Rep. Maria Elvira Salazar (R-FL) followed closely with a 5.97 z-score and 37 trades versus her 1.88 baseline, while Sen. Tina Smith (D-MN) hit 5.59 and Rep. Lloyd K. Smucker (R-PA) reached 3.98. These figures represent statistically unusual acceleration in personal portfolio activity.
Public filings show the trades clustered in specific sectors. Salazar disclosed purchases totaling hundreds of thousands of dollars in March and May 2026 across names including Amgen, Honeywell, Boeing, Cisco, FedEx, United Rentals, Citigroup and Goldman Sachs. Case added Apple shares through automatic dividend reinvestment in his spouse's account. Warner executed sales in several iShares ETFs and First Trust Tactical High Yield ETF while adding positions in Microsoft and Wells Fargo. The overlap between these holdings and the lawmakers' committee assignments on financial services, appropriations, and foreign affairs has drawn public scrutiny, though all transactions were disclosed within required timeframes.
The timing of the surge raises questions. Salazar reported no trades throughout 2025 before this burst of buying. The activity coincides with congressional debates over technology regulation, defense budgets, interest rate policy and potential reforms to congressional stock trading rules, issues several of these members have engaged directly. Warner's trades, in particular, come as his Senate committees monitor economic intelligence and emerging sectors like artificial intelligence. While baselines reflect years of lower activity for most, the current 90-day counts suggest either renewed market conviction or heightened responsiveness to legislative developments.
Broader market context may also play a role. With major indices pushing higher on AI optimism and industrial rebound signals, these filings show lawmakers positioning in both established tech names like Apple and Microsoft and industrials tied to infrastructure and aerospace. Public discussion around the disclosures has intensified calls for blind trusts or outright bans, a topic Case himself has co-sponsored legislation on in prior sessions. Whether this represents routine portfolio rebalancing or something more notable remains to be seen as additional filings continue to appear.
