The last 2 $heff FDA approvals are still trading well above entry. There will be a pullback at SOME POINT for sure but just no way in hell its going back to even past $13-14 IMO.
Look at DNDN, was 40 before approval and opened around $53. It did its pull back from $54-50, then right back to $57 the next day and closed back at $54.
Will probably see similiar action, if not less of a pullback. SOMX did the same, little pullback after it opened double but then ran higher shortly after.
