We have not had these for a long time, but when we had these...

We have not had these for a long time, but when we had these they were usually some positive announcements (?). That is what I am expecting also now.
This is a management action, not a scientific thing IMO. Would it be only made by Prana itself, I would think that there would be no need for trading halt for several days, in fact 4 days. So I think that there is an other company, perhaps the long waited "Big Pharma" as the other "partner" of this future announcement.
What ever it is at least the down trend ended for 4 days.
