Depends on your time frame and tax position. It's typically much better tax wise to hold a position for year and if you look at the longer term trajectory of the markets that GTAT is in, this will be higher a year from now, barring a major market correction - always a possibility. But look at TSLA and NFLX and SPWR when they had news that really turned their investing thesis around. Yes, they surged mightily on those day but basically that was just the beginning of the upswing. So many investors who have never heard of GTAT are learning today about the company for the first time and it will take time but they will buy in too. THis is maybe the second inning right now - much much more possibility for upside. I see $13-$15 by the end of the year, especially if there is more bright news about the LED market.
