The absence of active-manager buying suggests the cluster is index-driven, not a conviction call. Monitor subsequent 13F filings for active fund participation or any catalyst that could explain passive accumulation. No immediate price action expected from this filing alone.
Executive Summary
Three mega-passive institutions (Vanguard, Fidelity, Morgan Stanley) collectively added $811.6M in RNAM shares during Q3 2025, increasing holdings to $1.55B. All buyers are passive/index funds, suggesting the accumulation is likely due to index rebalancing or weight increases rather than fundamental conviction.
