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.
  • tax_withholding-22 points

    transaction_code = F

    Tax withholding on vesting shares is mechanical.
  • delayed_filing-6 points

    reporting_delay_days = 6

    Filing delay exceeds the configured threshold.
