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.

The record on $BLDR

Coldpine has parsed 27 disclosed trades in $BLDR by 1 member of Congress, drawn from 12 periodic transaction reports dated Jul 19, 2024 through Sep 25, 2026. All of them came from House members, all filed by Democrats.

Of the 27 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 36 days: a $BLDR purchase by Rohit Khanna dated Aug 4, 2025, disclosed Sep 9, 2025. How late filing is measured across all of Congress is in the late-filers study.

27 of the 27 trades that list an account holder (100%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Activity peaked in 2025 with 13 trades.

Across the 22 purchases Coldpine can price, $BLDR moved -3.01% on average between the trade date and the disclosure date, against +0.23% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 32% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
