And one more thing. Although technicals may call for a pull back (I've read as low as $3.13), there does seem to be support in the $3.70s. With trial completion announcements expected in a few weeks and of course data two months later, I would think anything around $3.80 would be a decent buy in.
I plan on loading up some more soon. Just waiting for the DEA and EMA to give ARNA some news so I can hopefully squeeze another dollar or two out of that stock.
