Sample · the intelligence layer

Coldpine signal scoreA 0-1 composite from four weighted factors: disclosure speed, trade size, cluster activity (multiple members buying the same name), and the member’s track record. ≥ 0.65 is the high-conviction tier; ≥ 0.50 is moderate. Trades from trust-managed members are penalized (× 0.2 multiplier). It’s research, not a recommendation.

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.

Longest gap, days

Tina Smith has 8 trades on record with both a trade date and a disclosure date. The median one was disclosed 3 days after the trade, against a median of 37 days across the Senate. Of the 171 members with three or more dated trades, 161 have a longer median.

None of those trades was disclosed more than 45 days after it was made, the STOCK Act's reporting window (across the Senate, 43.7% were). Dated trades on record run from Jan 27, 2026 to May 7, 2026.

By the owner field on each report, every one of the 8 trades is reported as a spouse's.

Lag is the disclosure date minus the trade date, from the filing itself. Trades with a missing or implausible date (outside 0 to 1,000 days) are left out of the lag figures. How every member compares: the STOCK Act late-filer study; how the data is built: methodology.
