Arena Pharmaceuticals, Inc. (ARNA)

While I love to see 5 figure gains in two accounts and a smaller gain in my ROTH, I can almost guarantee you this spike will be short lived and the shorts will double down from the $6's - they drove it down 20 cents going into the close. And holy cow, look at the volume! Nearly 110M shares! Almost half of shrs out! I've never seen so many 500k+ share blocks trade before, amazing to look at the raw data on Quotetracker.
