I hold Amarin, a biotech company. Bought at 2.05 a month ago and has been steadily climbing. There's been a lot of positive activity in particular over the last two days, pushing the price from 2.35 to 2.90 which is the highest it's been since October 2013. There's an earnings release this Thursday. Is that usually a good sign to hold onto my shares longer? Thanks for your help.
