AKE Chart, page-743

If you don't need to sell it's really simple , hold , wait for the recovery.
A few years back I remember I bought XRO at $82 and it went to $160 and I did not sell, and then it went all the way back to $85, I did not panic sell and 4 months later it was back at $155.

The moral of the story is do not panic sell if you are in a quality stock , wait it out , there's nothing worse if you sell at $8.90 and 4 months later it's back at $13.
