Make sure that you change your cover-limit orders at least by -100 bucks. Why to leave free money on the table. No new buys...no short covering now... extreme-bubbly-valuation ==> sudden lack of bid scenario might develop one fine morning and you may regret it, if your higher-set order to cover gets executed needlessly. All IMHO of course.
I second this. As I said before, MMs occasionally take it back up to push out shorts, then let it go back to its real pace. Don't rush. The thing is going down. And the pretty thing is, the lower it goes, the faster it goes. Magic!
