CLDX Celldex Therapeutics, Inc.
Executive Summary
A mixed institutional cluster in CLDX for Q3 2025 shows two mega-passive buyers (Wells Fargo, Invesco) adding modest positions totaling $1.6M, while three mega-passive sellers (Morgan Stanley, UBS, T. Rowe Price) trimmed $11.8M in holdings. The net selling pressure of ~$10.2M from passive rebalancing is notable but lacks active-manager conviction, suggesting routine portfolio adjustments rather than a fundamental thesis.

Actionable Insight
The cluster is entirely passive — no active manager signal. The selling by Morgan Stanley and UBS may reflect index rebalancing or risk-management adjustments, not a negative thesis. Monitor next 13F for active-manager entries or exits; the lack of activist/hedge-fund interest keeps the stock in a wait-and-see posture.
