Greedy dude. Sell now and re-position. The news/event has occurred. At least for the foreseeable future, this stock will trade in the $50s unless there is another significant news/event such as partnership deal or buy-out. So take your profit and enjoy it. A bird in hand is worth more than ten in the bush.
You are right my short friend" a bird in the hand is worth 10 birds in the bush", but bad advise isn't worth spit. Don't sell buddy Dendreon has a long way to go. They are going to go it alone as Amgen and Genentech did. If you must sell then sell your initial investment and ride your profit you made with this stock up. Remember if you sell out your out. Then you will have to find another stock to take Dendreons place. That won't be easy. You have a gem here don't let it slip through your fingers. If you knew that apple would have exploded upwards would you have sold it? As for me I'm keeping my Dendreon shares, See ya in chursh. .
