Conflicting signals; hold neutral stance
Signal Basis
Institutional net buyer count exceeds sellers (546 vs 427) but net value declined $1.38B; insiders net sold $5.66M against $0.31M bought in 30 days. Divergence without clear conviction.
Confirmation
A sustained shift in institutional value flow or insider direction would break the stalemate.
Invalidation Risk
Acceleration of insider selling or a unified institutional sell-off would tip bearish.

See the institutional 13F filings behind this signalSTT does not currently show a 13F-and-insider convergence signal — its insider confidence score is 10/100, below the threshold this product uses to flag combined buying pressure.
13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
