I have never heard of LEVP - sorry. And I dont follow ALXN - when did ALXN get approval? I am really referring to instances where a small bio which doesn't have much in the way of approvals aready reacts immediately preceeding and post approval. It's a pretty obvious trend over the last 2 years from the names I have followed, but it doesn't hurt me if you don't pay attention and want to be dismissive of it. There are occasional exceptions - but the vast majority of stocks have sold off significantly post approval and MANY are lower then before they got approval and all that I watch are much lower then the highs they got on the first day trading post approval.
