I'm invested Provention Bio who was one of the one

I'm invested Provention Bio who was one of the ones to get BTD last August. They were trading around $10, went down to $9 upon getting the BTD for some reason, and are now at $16. Their big pop had actually come a couple months earlier when they announced some results, and it has continued to gradually climb through some ups and downs as the push towards their BLA later this year.
