Palo Alto Networks is trading 3.6% down at $380.23, with sympathy selling after Fortinet’s results and outlook unsettled cybersecurity investors.

  • Reports said Fortinet’s reduced service-revenue forecast contributed to its sharp drop, while Palo Alto Networks fell alongside other security names; no new company-specific catalyst was identified.
  • The decline came amid a broader software selloff, with the software ETF down 4.26% during the regular session. Available evidence points to sector pressure rather than a Palo Alto Networks announcement.
