Strong institutional accumulation offsets light insider selling
Signal Basis
Institutional 13F data shows 945 holders with total value of $20.86B, net inflow of +$9.39B; 548 net buyers vs 388 net sellers, 248 new buys vs 104 exits. Insider activity shows only 6 sells totaling $26.26M with no buys — a small divergence that does not override the dominant institutional bullish signal.
Confirmation
Further increases in institutional holdings or any insider buying would confirm the bullish thesis.
Invalidation Risk
A sustained rise in insider selling or a reversal in institutional accumulation would invalidate the current bullish outlook.
The scenarios above are AI-generated directly from institutional holders' Form 13F filings on SEC EDGAR and describe historical patterns only. Not investment advice — see the underlying institutional filings linked below.
See the institutional 13F filings behind this signalLYB 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.
