The problem with that is if the crash is only say... 5-8%... you get the move in your favor but you still could lose your investment. Something to take note of is the fact that hedge funds and money managers are having one of their worst years on record... they are sitting on tons of cash as well. They have to hit certain benchmarks, so they will be buyers on any dip. That will be standing in the way of a massive drop in my opinion...
