Ownership vs. money flow
DivergingInstitutions 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.
