The cluster is dominated entirely by passive/index rebalancing, not active conviction. With zero active manager participation and poor historical report performance on CHYM, this filing provides no actionable directional signal. Monitor for any active manager 13F filings or insider buying for a stronger read.
Executive Summary
In Q4 2025, a mixed institutional cluster formed in Chime Financial (CHYM) with two passive mega-managers (State Street, Morgan Stanley) adding $10.5M in combined positions while three other passive mega-managers (Vanguard, BlackRock, Fidelity) trimmed $7.8M. The net buying of $2.7M is modest relative to the $6.3B market cap, and all activity comes from passive/index funds, not active managers, weakening the signal. Historical performance on CHYM reports has been poor (0% win rate at T+20, average -22.55% return), and the calibration data shows low observed win rates for scores 6-8, suggesting limited predictive value from this cluster.
