Institutional inflows diverge from persistent insider selling
Signal Basis
13F data shows strong institutional accumulation: net value change of +$12.3B with 861 buyers vs. 776 sellers. However, insiders have made 32 sales totaling ~$26.2M over 90 days with zero buys, creating a clear divergence.
Confirmation
A shift in insider behavior—such as insider buying or a cluster alert—would confirm a bullish tilt, continued selling without institutional reversal would confirm bearish.
Invalidation Risk
A resolution of the divergence—either institutional selling picks up or insider buying appears—would invalidate the neutral stance.

See the institutional 13F filings behind this signalNOC does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, 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.
