Q1 13F data reveals net institutional buying of $13.8B, with 692 buyers versus 489 sellers—a decisive accumulation wave. Insider selling totals just $748K over 90 days, negligible relative to the institutional flow.

Confirmation

Continued institutional inflows or a pickup in insider buying would reinforce the bullish case.

Invalidation Risk

A reversal to institutional net selling or a significant uptick in insider disposal would nullify this thesis.
