Bear versus Bull

Let me reduce this to a few sentences.

The expression "Bears have to get going" to push the market lower is absurd.  You can't push the market lower by shorting.   All you do is set a target for a stop run.  This adds fuel to the bulls. 

Bull can push the market higher....all they have to do is buy.

Bears have to be smarter than bulls...using the bulls own energy against them. 

OK, get it?   This is not bears versus bulls.   It is about when when bullishness is exhausted....do the bears still have the wherewithall and/or the nerve to jump in at that point.
