The $54.2M exit by Ninety One UK represents a material reduction in institutional ownership. Monitor for additional institutional selling in the next 13F cycle and any insider trading patterns that might corroborate a broader thesis change.
Executive Summary
Four small asset managers collectively doubled their Planet Fitness positions in Q3 2026, adding $1.6M in new holdings, while Ninety One UK fully exited a $54.2M stake. The net institutional flow is heavily negative by dollar value, driven by a single large exit that dwarfs the accumulation.
