Yeah of course, a correction could come at any time, so one thing would be to close longs along the way (which means selling) and another thing is going short (which means going on margin, and is a step further than some folks are willing to go).  Personally, I don't mind selling small amounts on the way up, but going short is playing a bit harder ball than is within my bailiwick. 

To be more specific, I could see breaking above $10k, by 10% or even 15% and then correcting below $10k,,, but who knows.. $10k could become a new floor, also, as others have postulated that possibility, which is not unreasonable, either.
