Look on the bright side. XLS is still trading high. You have only just begun to lose money. Just wait until the lack of bookings due to congress taking a sword to the defense budget. Then you will really lose money.
apparently somebody dumped 1.15 million shares at close today from what I am seeing that caused the EOD drop.
I say hang in there, this stock is still young and the company has a proven track record. It could jump very quickly to a new price and stay there for a while.
I think what we are seeing now is the weak hands who thought this would immediately jump 50% after the spinoff selling their shares due to lack of patience. Once that is done it will start to move up again.
