The Fibonacci extension on the SP500 chart shows that it has reached the 618 halfway move and then blasted past the 100{37471d21a8c4ca072ce05e5c1dfbdaec01ff2ef8391827b0199be0aecce32fae} measured move. So what will happen next? When hot terms like A.I. are used to advertise, say, toothbrushes, have we finally hit the peak? Is this a sign of exhaustion, or are we just getting started?
