Low filing signal

This filing has a meaningfully negative filing-only score. It is likely less useful as a positive insider-activity signal.

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.
  • amended_filing-6 points

    is_amendment = true

    Amended filing: the original transaction may have been restated.
  • delayed_filing-6 points

    reporting_delay_days = 84

    Filing delay exceeds the configured threshold.
