Not sure so only guessing... the over reaction to AF's slanted negative article caused a drop in share price below what made sense and buying now is just going back to the baseline (around $7). I think also at these levels and with the Elan statement (which leads people to think others are seriously interested in buying Amarin) no one wants to get caught with their pants down which shifts the share price in favor of longs who are buying due to the artificial dip..... now if there was a major institution buy etc., options, etc. I have no clue. Amarin at the current share price is ridiculously low.... also NCE is "looming" again which always leads to a slight uptick and then a drop after it's not granted. All guessing here.
Sentiment: Strong Buy
