Institutional net accumulation of $275.5M with 415 net buyers vs 374 sellers. A single insider sale of $2.79M is negligible and does not offset the strong institutional inflow.

Confirmation

Insider buying or continued institutional accumulation would further solidify the bullish view.

Invalidation Risk

A sharp reversal in institutional positioning next quarter would invalidate this bullish thesis.
