Medium term SP500 might found support at 50% Fibo retracement of potential Minor first of Intermediate fifth of Primary third wave sinse 3/6/2009. The price could drop to lower $1710 level and hit 61.8% Fibo.
This suggesting is based on the Fibonacci extention sequence, i.e. every third wave in this bull market unfolds to 161.8% Fibo of the first wave. If we follow this ratio then Primary wave three target should be far and away from here.
