As of Q2 2026, 37 SEC-registered investment managers reported holding QLYS (QUALYS INC) in their latest 13F filings, with a combined reported value of $2.34B across 17.10M shares.

Compared with the prior quarter, 3 opened new positions, 19 added to existing stakes, 15 trimmed, 3 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

QLYS is classified in the Technology sector.

All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
