✦ Quant Ownership Signal how this is computed

Distributing
  • The number of reporting institutions increased by 2 in the most recent period (2026/Q3).
  • Total institutional ownership fell 1.5 percentage points.

As of
2026/Q3 vs. prior period

Ownership vs. money flow

Diverging

Institutions trimmed shares last reporting period, and the stock has seen net inflows 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.
