✦ Quant Ownership Signal how this is computed

As of
2026/Q3 vs. prior period

Ownership vs. money flow

Diverging

Institutions added shares last reporting period, and the stock has seen net outflows in main-fund flow over the last 20 trading sessions - the two are pointing in different directions.

Institutional ownership changes are reported quarterly with a lag; fund-flow data is daily. Treat this as a directional cross-check, not a precise timing signal.
