Qualys is trading 8.33% up at $201.54 after no fresh company-specific catalyst was identified.
- Firmer Nasdaq futures, a weaker dollar, and broader risk-on sentiment may be supporting the move, with Nasdaq futures up 0.55%.
- Latest developments were its August 4 earnings beat, raised 2026 guidance, and August 13 cloud-security product announcement.
- Neither development directly explains the August 17 pre-market jump.
