As we trade at the top of this wedge, volume has been on a decline. Also, bearish divergence on the weekly TF -- not great! And, it would only make sense for us to go down for the E wave before breaking out. This is strictly a technical analysis, so yes, Carnival could definitely pump if they come out with some great news -- doubtful though as cruises keep getting cancelled and delayed.
I am personally picking up $30 puts with a 8/20 expiration. I am certainly not betting heavy on this move as I rarely have luck with puts. (This is not financial advice)
