I absolutely agree, if you are unhappy with your holding to sell. I would not advise "moving on"
There is no reason for your portfolio to get beat up over principal.
However if you do sell, and you have spent a lot of time doing DD here, then keep a close eye on it. IF you sell, there is NOTHING that says you can't buy back in.
There are no moral imperatives with holding a stock. The sole reason to hold a stock is to sell it and make money.
I hope this turns around soon, and we can ALL make money. Right now it is limited to insiders and management.
Good Luck
(I) can't wait
