As of Q2 2026, 28 SEC-registered investment managers reported holding SNDX (SYNDAX PHARMACEUTICALS INC) in their latest 13F filings, with a combined reported value of $798.81M across 36.67M shares. That is +3.9% by share count (+1.38M shares) versus the previous quarter, while reported value moved -2.8%.

Compared with the prior quarter, 1 opened new positions, 17 added to existing stakes, 8 trimmed, 5 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

SNDX is classified in the Health Care 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.
