The secular uptrend on a 13-year time frame remains intact. SPX's move below the midpoint was not sustained, and price has rallied back above the midpoint of the channel. But on this much larger time frame, it's appears SPX is just making very little progress—other than chopping around the mid-point of the 13-year channel!
Interesting to refresh the chart and consider whether the lower edge of the channel may still be tagged as hypothesized last fall.
