Announcing submission/acceptance creates angst until approval
I see it as the company is making progress, and as a shareholder, am much more confident that I have a winner. I don't expect the application my biotech has submitted will be denied review, and I don't expect that once the application is accepted for review it won't be approved. I have those expectations because that's what my research tells me. If the application is denied review or upon review gets a Complete Response Letter, which are material events, I would expect it to be PR'd then. By PRing submission and/or acceptance of review there might be a little angst since nothing is ever a 100% but at least I'll have strongly positive expectations that it will be reviwed/approved and have that feel good feeling till that decision is made. There is no reason not to PR submission of application based on my experience of a biotech I owned and of recent examples of Vertex and Adaptimmune PRing start of rolling review submission a couple of months ago that was noted on this board.
