The cluster is entirely passive/index-driven, likely reflecting PONY's inclusion in or rebalancing of major indices. No active fundamental thesis is evident. Monitor for any active manager 13F filings in subsequent quarters for a genuine signal.
Executive Summary
Three mega-passive institutions (State Street, Fidelity, Morgan Stanley) significantly increased their PONY positions in Q3 2025, with Fidelity and Morgan Stanley roughly doubling their stakes, while BlackRock trimmed a tiny position. The aggregate net buying of $371.5M from passive index/rebalancing flows suggests no active fundamental thesis, but the scale of accumulation is notable for a $3.5B market cap stock.
