The cluster is dominated by one mega-passive seller (Fidelity) near-exiting, which accounts for ~87% of all net selling value. Quant funds (Two Sigma, Point72) adding aggressively at lower prices suggests a potential catalyst-driven thesis, but the massive Fidelity exit raises structural demand concerns. Monitor for any fundamental disclosure (NCT data, partnership, financing news) that could explain the divergence between quant buying and mega-passive selling.
Executive Summary
Q4 2025 13F cluster for CATX shows a mixed institutional picture: two mega-passive funds (Fidelity, BofA) aggressively reduced holdings, while two quant funds (Two Sigma, Point72) and two other mega-passive funds (Wells Fargo, Morgan Stanley) added moderately. Aggregate net dollar change across tracked funds is negative, with sellers reducing by ~$35.0M vs ~$5.1M in new buyer accumulation. The vast majority of the selling dollar value came from Fidelity, which near-exited a ~$34.3M position.
