Positive filing signal

This filing has a modest positive filing-only score. Treat it as a useful flag for review, not as a buy signal.

How this score is calculated
  • open_market_purchase+12 points

    transaction_code = P

    Code P is a discretionary open-market purchase.
  • direct_ownership+6 points

    direct_or_indirect_ownership = D

  • large_holdings_increase+8 points

    large-holdings-increase signal matched

    Reported acquired shares meet the configured percentage of post-transaction holdings.
  • timely_filing+4 points

    reporting_delay_days = 2

    Filing reported within two business days of the transaction.
  • 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.
