[闲谈] Why I never play bio stocks any more -- look at ARNA

yijianmei

Used to play some bio stocks last year, including BCRX, ARNA, etc., but didn't really make any money. Boy, am I glad that I haven't touched them since. Check out ARNA, diet drug got rejected by FDA after hours today, and its shares dropped to $2.2. Just two days ago, it was at $7.x. What a waist-cut!
