I have both ARRY and CLDX from $4. Trust me and stay away from naked_finger. He bought ARRY at 3.70 and sold at 4.27. He keeps on doing this to many stocks. On ARRY msg board he was saying "CLDX is a junk". CLDX is a perfect example of what could happen if you are a player for 30-40 cents gain. I was like this guy before and look what happened to me, I lost $160 gain per stock in REGN.
