Coldpine’s read
Smith's Finance Committee seat carries jurisdiction over healthcare and Medicare policy that touches medical-device makers like DexCom. The spouse-owned sale of $100K–$250K clears at the higher end of typical disclosed ranges. Two other members sold DXCM in the same direction within 30 days, and the 3-day disclosure lag means the market has had limited time to absorb the filing.

The record on $DXCM
Coldpine has parsed 35 disclosed trades in $DXCM by 7 members of Congress, drawn from 24 periodic transaction reports dated Aug 21, 2023 through Jun 30, 2026. That is 32 trades from House members and 3 trades from senators, filed 23 by Democrats and 12 by Republicans.
Of the 35 trades with a known filing lag, every one was reported inside the STOCK Act's 45-day window. The median lag was 25 days. The longest was 38 days: a $DXCM purchase by Michael T. McCaul dated Aug 4, 2025, disclosed Sep 11, 2025. How late filing is measured across all of Congress is in the late-filers study.
29 of the 33 trades that list an account holder (88%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $DXCM purchases (16), and Michael T. McCaul the most sales (5).
Activity peaked in 2025 with 12 trades. The busiest single month was May 2026, when 2 different members disclosed $DXCM trades.
Across the 21 purchases Coldpine can price, $DXCM moved +1.18% on average between the trade date and the disclosure date, against +3.48% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 48% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
