As of
2026/Q3 vs. prior period

Ownership vs. money flow

Aligned

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