CapitolRadar analysis
38 trades split into 23 buys and 15 sells
KMX’s tracked activity covers 38 trades by three distinct traders from October 7, 2020 through January 29, 2026. Buys account for 23 transactions, compared with 15 sells. The small number of traders is an important limitation: the activity reflects a concentrated sample rather than broad participation across many filers.
The disclosed quarterly pattern is uneven. The largest listed cluster was 2022 Q4, when all seven trades were buys. Other all-buy quarters included 2024 Q1 with two trades, 2023 Q3 with one, and 2023 Q2 with one. By contrast, 2025 Q3 recorded six trades—two buys and four sells. Both 2025 Q4 and 2026 Q1 had one trade and no buys. The listed quarter data therefore shows periods of concentrated buying as well as more recent quarters containing only sells, but the limited sample does not establish a persistent trend.
18 of 23 buys came from Ro Khanna
Ro Khanna accounted for 18 KMX buys, with the latest dated August 4, 2025. Michael McCaul recorded three buys, most recently on August 31, 2022, while Susie Lee recorded two, most recently on October 19, 2020. Together, those counts equal all 23 tracked buys, making the purchase history heavily concentrated in one trader.
Six other stocks overlap across two KMX buyers
Two of the KMX buyers also purchased each of AJG, INTU, BSX, TER, DHR, and MA. These overlaps identify shared disclosed holdings only; they do not indicate coordinated trading or a common rationale.
Congressional transaction reports may be disclosed up to 45 days after a trade, so filing visibility can lag the transaction date. Reported transaction amounts are generally presented as ranges, meaning any amount-based totals are estimates. With only three tracked traders, conclusions about timing, sentiment, or broader market significance should remain limited.
