One interesting aspect of Tuesday’s action is the SPY gapped up above Monday’s close, and never filled that gap. This made the 2nd day in a row with an unfilled up gap. The study below is one I’ve shown before in the subscriber letter. It examined other times SPY left 2 unfilled up gaps and closed at a 50-day high. All stats are updated.

The size of the follow-through isn’t terribly large, but it has been very consistent that some follow through was achieved in the next few days.
