Context This was an administrative disposition to cover taxes on vested restricted stock units (a routine corporate payroll/tax action), not a market sale that necessarily signals the insider's view on Rapid7's stock. For retail investors, purchases are generally more informative than routine withholdings; this report documents compensation-related withholding rather than discretionary selling.
