✦ Quant Ownership Signal how this is computed

Distributing

The number of reporting institutions decreased by 4 in the most recent period (2026/Q3).
Total institutional ownership fell 8.0 percentage points.

Institutional ownership

Held by institutions: 93.35% -8.01pp
Institutions: 265 -4
As of: 2026/Q3 vs. prior period

Ownership vs. money flow

Aligned

Institutions trimmed shares last reporting period, and the stock has seen net outflows in main-fund flow over the last 20 trading sessions - the two line up.

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.
