The fierce rally in the SPX is rapidly approaching upper part of the century-old trend line, as well as a decade-and-half old trend line.

This is an extremely rare moment where the froth in the markets are at the dangerously high levels. If history patterns are to be believed, we may enter a 9-10 years of lull markets with non-positive returns.

At between 7500-8000 level, the index may start going sideways before undergoing its overdue correction. Thus, 3500-8000 may become a large sideways boundaries for the index till late 2035.
