1964-74 was the first large-scale multi-year correction since the great depression. Large enough and long enough that it took a decade to recover from it. I noticed that it had a very similar look to what we have been seeing since 2018. So, I overlaid a scaled version (scale factor = 31) of the 1964-74 market correction (the blue line). Now the time frame does not match, but surprisingly the high and low peaks align amazingly well. If the S&P does repeat the 64-74 pattern, then there is still major correction in store for the S&P over the next year.
