Dark pool just lit up at 12:09 PM — $172.5M $GOOGL buy through NASDAQ Carteret.

Context matters here: $GOOGL has been flat to net-sell in the dark pool for over a week. We saw -$906M on August 5, -$36M on August 12. Now institutional buyers are stepping in at scale.

This is a positioning shift. When dark pool flow flips from persistent selling to a chunky buy like this, it's often early institutional accumulation before the crowd catches on. Not a guarantee of upside, but it's a signal worth tracking — especially if you're watching $SPY and $QQQ for broader tech rotation.
