Agree Rain- i'm one of those and while I know I want to hang on and most likely will- Monday will be a nail biter. Unless the PR contains completed actions as opposed to "we're working on/we plan to, etc.- it may be perceived as fluff/damage control.
You also make a good point- unless a trader really knows what they're doing- be careful not to get caught in panic sell that results in a major rebound. It's happened here before.
