Yes, it was that news that caused the rise to 23. I had a sell there, but you think they gave it to me? Hah!
Long term, I like ELN very much and actually had it before the "death drop" a couple years ago. As far as any biotech stocks are concerned, I think it is the best. Ty is a wonderful drug and they have several things lined up for Alzheimer's down the road a bit.
Nonetheless, it seems like the most manipulated stock around, especially near options expiration. Makes for good trading.
