I have to admit I have questions on this too. I bought into this head and tails very few PSDV. Of course PSDV was the one that took off before. All the talk was PSDV has better pipeline and was worth more. Well I have been taking profits on my ALIM and reinvesting in PSDV thinking it is going to catch up. As we can all see I should have stayed put with ALIM, could kick my self in the butt for the money I missed, luckily still hold a few so did not miss everything. I still think PSDV is going to move but I want it to move now!, not later.
I don't short. Ever. I don't play options at all. That's for people who want to lose. I hold alim but will sell very soon as this is way overvalued when they pay 25 million to psdv.
I hold 250k shrs of psdv and 100k shares of alim at this time.
