POST Post Holdings, Inc.
Executive Summary
A mixed institutional cluster in POST for Q3 2025 shows three buyers (Morgan Stanley, Schwab, and Renaissance Technologies) adding $68.5M in new holdings, while two sellers (Fidelity and Norges Bank) reduced positions by $168.5M. The net selling pressure is dominated by Norges Bank's full exit of a $136.3M position, which overshadows the buying activity. The cluster is dominated by passive/index funds on both sides, weakening the signal, though RenTech's doubling of its small position adds a quant-driven bullish note.

Actionable Insight
The Norges Bank exit is a significant signal from a sovereign wealth fund, but the buying from Morgan Stanley and Schwab suggests passive rebalancing rather than a thesis change. Monitor for any catalyst (earnings, M&A) that could explain the divergence. The net selling pressure may weigh on the stock in the near term, but the passive buying provides a floor.
