Dear Cro,,,
You cry like a 2 year old and ask us to talk you out of selling all your GTCB stock and buying ZGEN. Then the stock moves up a few pennies and you're giving us all directions on how to trade GTCB. I feel pretty sure I'm not the only one not seeking your advice or who does not really care whether you are buying or selling (unless you are trading in 100,000 share lots). I believe you posted you are a retired physicist and I'm sure your very smart and probably no one on the board would debate "string theory" with you.
There is an old saying in the market; if you can not sleep at nite, sell down to the point where you can. Another old saying; the stock market does not offer a college education. I take that to mean we do not always understand why stocks move up or down at the time they are doing it. Try to be patient, this is a stock where those who are patient will do well.
