In a recent article featured in our twice monthly McClellan Market Report newsletter, we featured the chart shown this week. It was inspired by some work done recently by famed technical analyst Peter Eliades, who has been a newsletter writer for many years and is the proprietor of stockmarketcycles.com.
The basic point is that a period of 150 months (12.5 years) shows up in lots of places as the time distance between several important turning points for stock prices. The price data in the chart this week is the log value of the monthly close of the DJIA. Using log scaling allows us to better see the turning points without the effect of arithmetic scaling interfering with the view. mcoscillator.com/learning_center/weekly_chart/the_magic_of_150_months/
