If the markets do well for the rest of the day without going berserk I'll probably hold overnight. If we have some riduculous spike up this afternoon, I'll take profits on the theory that we'd then fall flat on our faces tomorrow.
If I do hold overnight, I'll adjust my stop upward & watch it carefully during AH and PM tomorrow. (I don't know about other brokers, but stop-loss orders at Fidelity don't apply outside of regular trading hours.)
