CapitolRadar analysis
28 trades split narrowly toward sales
28 tracked IDXX trades comprise 13 buys and 15 sells by three distinct congressional traders between March 29, 2021 and April 13, 2026. That produces a near-even direction mix: sales exceed purchases by two transactions. The activity concerns IDEXX Laboratories, Inc., classified in Healthcare and Medical – Diagnostics & Research.
The quarterly data provided are uneven rather than continuous. The busiest listed period was 2023 Q4, with five trades: two buys and three sells. Next was 2024 Q1, with three trades, including one buy. Both 2023 Q2 trades were buys, while both 2022 Q4 trades were sells. The listed single-trade quarters were 2023 Q3, 2025 Q3, 2026 Q1 and 2026 Q2; the 2023 Q3 and 2026 Q2 entries were buys, while the other two were sells.
10 of 13 buys came from Ro Khanna
Ro Khanna accounted for 10 purchases, or most of the 13 tracked buys, with the latest recorded on April 13, 2026. Tommy Tuberville made two purchases, most recently on April 3, 2023. Diana Harshbarger made one purchase, dated August 24, 2022. This is a small sample of only three distinct traders, and the disclosed facts do not identify which traders made the 15 sales.
6 overlap tickers each involve one buyer
One of the IDXX buyers also bought each of ADI, ARES, CARR, CSCO, EW and HON. The data do not specify whether the same buyer appears in all six overlaps, when those other purchases occurred or how large they were, so the overlap is descriptive rather than evidence of a broader pattern.
Congressional transaction disclosures can lag activity by up to 45 days, so filing visibility is not necessarily contemporaneous. Reported transaction values are generally disclosed as ranges, making any amount-based totals estimates; no dollar ranges are provided here. The limited trader count and uneven quarterly sample also constrain broader conclusions.
