SP500: Bears take Control?

Weekly View of the S&P500 which is beginning to show signs of a change in direction. We need the 2600 price level to hold if we want to buy back into this pull back. I will be looking at buying around between the 2016 .50 & .618 fib retracement. We are most likely in my opinion to get a move downward that mirrors 2011's pullback of -21.5% if this trend holds.
