As of Q2 2026, 8 SEC-registered investment managers reported holding PSTV (PLUS THERAPEUTICS INC) in their latest 13F filings, with a combined reported value of $961.89K across 220.08K shares.

Ownership is concentrated: the five largest holders account for 99.7% of reported value and the top ten for 100.0%.
Compared with the prior quarter, 2 opened new positions, 1 added to existing stakes, 5 trimmed, 1 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.
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.
