There's no telling what it might do from here, at the 1.618, currently. Could keep running, but volume is diminished as price continues. Little bitty inverse Head and Shoulders on RSI could be a tell tell of more upside. Next target up (not a straight line) could be the 2.618
SHOP just hit the 1.618 at $590. If it makes it to the 2.618 fib it will be $879. This could be traded but perhaps should be a long term hold considering that could all happen just this year, IF the imaginary channel is respected.
SPX seems to have left one channel to form another steeper upward one. It dipped to retest the previous channel. Seems well enough, but a divergence seems to be forming. Could test the top of the lower channel again, among other possibilities.
