I update since end june my correlation with august 1980. you see on the chart how the last month datas have been experiencing the same moves than in saugust-september 1980.
I used the first time, 82 open days ; THE ATTACHED GRAPH IS USING 150 OPEN DAYS. Normally it should be statistically difficult to find more than a 80% CORRELATION. i FIND 2 EXTREMELY INTERESTING CORRELATIONS, with september 1980 with a 94.96 % correlation and with March 1961 with a 95.58% correlation coef.
What is interesting is the correlation between the 2 predictions . Both past dates have a common output in the next 150 days
, SPX is up 7% exactly for both.
I think these correlations are not spurious correlations and tell something abouth the waves market experience again and again.
I find 1961 as an interesting date as it is a period of geopolitical tensions (JFK, Cuba, Cold war, kroutchev)
I cannot paste the file here too big with excel
you will find it on my yahoo list last message
Also both correlated dates are bear market rallyes followed by a strong sell-off which erase all gains until august 1982 and June 1962, then followed by a long bull market.
