No idea about what 4th wave in the S&P means...........
I only trade stocks, not indices, at least not yet. Sometimes stocks will move in unison with the index, but most times, I find, they go their own way. I find it very confusing to follow an index, and use that to get entry and exit signals in individual stocks, as the stocks give me all the signals I need.
Gold, intriguing, as usual. Best to just follow, and leave predictions alone.
