Since the market has been rallying lately and people are all positive again, when a sell off comes it really picks up speed as the downward spiral accelerates.
When people buy a stock, they research and deliberate a lot and fix various profit levels in their minds. They are careful in their decisions. What I like about shorting is when it starts to crash, all reason goes out the window and they panic, eventually selling at any price they can get. This is a great opportunity for traders with level heads to make better choices and go with the flow.
I don't know what the market is going to do today, it can skyrocket higher or pile drive lower, but at the moment I can see a lot of weakness and droopy chart patterns so shorts or inverse ETFs are the right play.
