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.

The record on $VMFXX

Coldpine has parsed 35 disclosed trades in $VMFXX by 1 member of Congress, drawn from 9 periodic transaction reports dated Jan 3, 2023 through Aug 29, 2024. All of them came from House members, all filed 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 23 days. The longest was 44 days: a $VMFXX purchase by Michael T. McCaul dated Jun 5, 2023, disclosed Jul 19, 2023. How late filing is measured across all of Congress is in the late-filers study.
