People who criticize others who are profiting legally have their own problems. People who comment daily on every move the market or an individual stock makes have a different problem. Good luck either way.
As for GTI, let's see where it goes if it closes the gap at $13. I assume that's a point the shorts might come back in. I assume the past several days of higher volume have been a short covering rally based on the extra 2 million short shares put on in July-August 9 period at about $10.
Personally have a partial position limit sell order in at $12.82. I find it difficult not to sell part of a position when a stock is up 50% in 4 months. Each to his own.
Good investing. Long GTI and SGG. Bought more SGG today in belief (hopes) that it will follow GTI in this move especially if GTI breaks past gap.
