It looks like GT has bought 9 shares for every 1 share that he has sold recently. Many CEO's don't draw much of a salary and rely on selling stock on occasion to pay the bills. He didn't buy nearly $600,000 worth one month ago to watch it go down in flames. As an insider, he is unable to sell those shares for 6 months if I'm not mistaken.
Do your own DD. I'm not responsible for anything I say.
