CapitolRadar analysis
60 trades skewed modestly toward sales
60 tracked ADP trades were reported by eight distinct traders from June 6, 2019 through July 30, 2026. The record contains 34 sales and 26 purchases, making sales 56.7% of activity and purchases 43.3%. That is a modest numerical sales tilt, but the sample remains small—especially when divided across traders and quarters—and trade counts alone do not show conviction, portfolio weight or rationale.
14 of 26 purchases came from one buyer
Ro Khanna accounted for 14 buys, or 53.8% of all tracked ADP purchases, with the latest dated April 13, 2026. Michael McCaul followed with five buys, last on July 28, 2023, while Josh Gottheimer had three, last on January 11, 2023. Marjorie Taylor Greene recorded two purchases, most recently November 12, 2025. Diana Harshbarger and Tommy Tuberville each had one. Together, these six named buyers account for all 26 buys in the supplied data, so the purchase pattern is concentrated rather than broadly distributed.
12 sales versus four buys in the listed quarters
16 trades appear across the eight quarterly snapshots provided, comprising four buys and 12 sales. The largest listed quarter was 2023 Q4, with four trades and no buys. The more recent entries were also sparse: 2026 Q1 had two sales, Q2 had one buy, and Q3 had one sale. Because several quarters contain only one or two transactions, quarterly comparisons are highly sensitive to individual filings.
Buyer overlap with other stocks was limited but repeated: two ADP buyers also bought each of PANW, MA, BSX, TER, DELL and META. These overlaps identify shared activity only; they do not establish coordinated trading or a common motive. Congressional disclosures can lag transactions by up to 45 days, and any disclosed dollar-amount ranges are estimates rather than exact trade values. Those reporting limits, along with the small samples, constrain conclusions from timing or direction.
