Dark pool volume for AAPL hit 21,463,740 shares this week. Independently, Joe Terranova, Steve Grasso, Josh Brown flagged AAPL on CNBC with buy-side calls. Neither signal alone is actionable. But when institutional plumbing (dark pool volume) and public sentiment (CNBC calls) point the same direction simultaneously, the convergence has historically preceded the ETF rebalancing flows that amplify the move.
