I know ARNA has the better drug - their pps has gone up quite a lot since the CELG disaster was released, although they're not going for MS off the bat, just UC - but UC is still a huge market. If both ARNA and AMRN pay off in a big way, I'm nearly set for life - they're my two biggest holdings, own them in IRA and cash account, plus a 3rd small position of ARNA in a ROTH, and a 3rd small position of AMRN in a 2nd cash account, been slowly building that one up $500-$1000 at a time when I have some extra money - shoulda added more to that one when we went down to the $2.70's, but it was a busy week, never got around to doing the transfer, now AMRN up 30 cents from the lows - nuts.
