✦ Quant Ownership Signal how this is computed

Distributing

The number of reporting institutions decreased by 3 in the most recent period (2026/Q3).
Total institutional ownership fell 4.3 percentage points.

Institutional ownership

Held by institutions: 109.48% -4.35pp
Institutions: 215 -3
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.
