Institutions pile in, but insiders keep selling – mixed signals
Signal Basis
Institutional data shows strong net inflows: total value rose by ~$27.7B with 1,141 net buyers vs. 942 net sellers. Yet insider activity over 90 days is entirely selling (14 trades, ~$37M, zero buys), creating a clear divergence between smart money flows.
Confirmation
A reduction in insider selling or the emergence of insider buys, coupled with sustained institutional accumulation, would tilt the balance bullish. Conversely, accelerating insider sales or institutional distribution would confirm bearish pressure.
Invalidation Risk
Either a reversal in insider behavior (buying) or a shift to net institutional selling would invalidate the neutral stance and resolve the signal conflict.

See the institutional 13F filings behind this signalGLW 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.
