Zoe, I tend to agree with you. It would be foolish not to take profit (speaking of those that bought below the .0255 area). That's just good trading.
However, I bought in the same range, and have not and will not sell until my target is reached. There is WAY too much room and potential to take ATRN out of my portfolio at this time. I don't usually hold stocks....I trade them, but sometimes certain scenarios DO present themselves. That sums it up.
