This sell-off has nothing to do with institutional investors lack of belief in Rida. It has nothing to do with Berger's character. Imo, it is 100% caused by opportunistic hedge funds and retail shorts just running down a little biotech company that has a history of this sort of thing.
Sorry boys but I believe you are not seeing the forest through the trees here. Rida is a nice sidebar for Aria but the real value of this company lies in Pona. Ariad is on sale right now.
