$PFE is sitting on its 200 Day MA, which is just below the 0.618 Fib.
This is where bulls need to step in and react on this support level to move this higher.
$PFE received some positive Phase 3 news yesterday that one of their respiratory drugs has given a significant immunity response...but I don't see this news showing any reaction yesterday when it released, this may come this week.
Impulse wave continues as shown
Getting below the 200 Day MA would show weakness for me and the $27 level would be the invalidation line.....but bouncing from here and $PFE is looking good to complete Wave 3.
