Institutional net buyers outpaced sellers 397 to 345 in Q1 2026, driving a $2.52B net value increase. Insider activity remained light with only $136K in 30‑day sales and a net $1.43M sell over 90 days, insufficient to reverse the institutional tone.

Confirmation

A second consecutive quarter of institutional net buying would validate the accumulation momentum.

Invalidation Risk

A surge in insider selling volume or a sudden shift to institutional net distribution would derail the bull case.
