Dow Jones Transportation have just finished their wave 5 cycles up. Which means we are in store for a larger correction down. There we are looking at retracements to the 0.382 fib at 7800 or a 0.5 fib retracement at 6700.
If transportation were to drop, the SPX and S&P is going to drop too. Transportations has always been a early warning regardless to do that.
