You are an idiot. The directors have been buying shares hand over fist for 3 years now on the open market. God your post just truly crack me up. The sad part is that NOBODY on this board even pays attention to them. You are truly a waste of space here.
Your reply about directors buying shares have nothing to do with the Topic about dilution. GTx has about $32M as of today. $42M as of March 31, 1st Q. Gtx burns about $10M per quarter. At the present rate of burn, GTx will have $0 cash by the end of the 1st q 2014. With $32m left, you don't wait until the cash completely runs out before you have to raise more. So the topic was better to dilute at $7 than $2. Usually, a dilution takes the stock down about 20%. Stock is usually discounted at least 15% to the market with new shares going out.
You can be sure that GTx will dilute, again. And if such dilution was done when the stock was $7, the next trading day will see this stock at about $5.50/share. And this could be any day now. What does this have to do with the directors buying shares? But some did sell, go look again.
