Filing-only score

-18 points

Compact filing score computed from stored Form 4 facts. Version v1.

Mixed or weak signal

This filing has a negative filing-only score. It may be less informative as an insider-activity signal and needs extra context.

How this score is calculated
  • direct_ownership+6 points

    direct_or_indirect_ownership = D

    Direct ownership reports the insider's personal stake.
  • derivative_transaction-16 points

    is_derivative = true

    Derivative exercise rows are less discretionary than open-market purchases.
  • missing_price-8 points

    price_cents is null

    Missing price reduces confidence in value-based signals.
