The Strong Bearish S&P 500

A sustained move under 4510.50 will indicate the presence of sellers. If this creates enough downside momentum then look for the selling to extend into 4438.50 and 4419.25.

Taking out 4419.25 could trigger an acceleration into 4327.50, followed by 4266.00, a main bottom at 4212.75 and 4137.50.
