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

Matsui's spouse committed over $1M to Intrinsic Exchange Group via a SAFE, a private, illiquid bet on a firm building natural-asset financial products—an area touching her Energy and Commerce Committee jurisdiction. The six-day disclosure is well inside the STOCK Act window and unusually fast given the private nature of the transaction. No other members hold this private name, so cluster signal is absent and the position is idiosyncratic.

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.
