This is why you short every time it pops. It takes days to rise 1 or 2% and minutes to drop. Shorting makes more faster!
What is interesting is how fast it can drop even in the face of news like this: Zillow says that 2 Million Homeowners No Longer Underwater and I drove Shelby Twp. last weekend. Unreal how many acres are going under development for new subs and new homes. Builders are under pressure to build, build, build.
