Well, let's see... The Dow and Nasdaq lost 2.2% this week, and IBIO lost 12%...
The Dow and Nasdaq lost about 2.2% in a month, and IBIO lost 23%.
So, I have a problem with your premise that IBIO "remained strong" I have some stocks that gained 20% this month; that is "strong"
After another pumpjob, IBIO is deflating like an old, bald tire.
