Check out Google finance link to a new article tonight titled "Analyst: Celldex aiming at accelerated approval with brain cancer drug". Might explain the after hours action......
100 shares at $20.89 isn't really "action". Let's see what happens premarket.
Maybe some will take notice tomorrow when trading begins but after hours really doesn't mean much with 26k shares traded. Cldx will get to 30+ by years end IMO.
I agree as to your year-end price objective.
On the surface the AH "action" raising showing an increase of about 58 cents appears to be a head fake. Only 100 shares up that much. Most show a decline from the closing price, but the article is positive.
