Comparison DJIA to NASDAQ 71 years later 21 This entry was posted in Analysis US Markets and tagged 71-year-cycle DJIA NASDAQ on July 23, 2015 by Ray Tomes. This is a comparison that I did some years ago. David asked about Kondratieff cycle now. I think the correct cycles to look at for stock market are 71 year, 35.5 year etc. This shows why.
