Gap and go
Traders came back from the long weekend with a vengeance, pushing stocks up handily at the open and not letting up. This is one of the few times that SPY's low was at least 0.5% above its prior close, while adding at least another 0.5% from open to close. Of the other times it's shot higher like this, only one ended up being a true gap-and-go. The others took a median of 7 trading days before falling back below the prior day's close (Friday's close in the current case).
