The cluster is dominated by a single large seller (Assenagon) whose $96.0M trim overwhelms the smaller buying activity. Monitor next 13F for continued selling by large holders and any insider buying to confirm conviction.
Executive Summary
A small institutional cluster shows 6 asset managers increasing NTNX positions by $5.9M in Q3 2026, while two sellers reduced by $96.0M, dominated by Assenagon Asset Management's $96.0M trim. The net conviction is bullish among the buyers, but the aggregate net dollar change is heavily negative due to the large seller. No insider buying corroborates the cluster.
