I've been reading about this 8.6 year Global Business Cycle or Princeton Economic Confidence Model. Took me some time to understand but still dun understand.
Aiyah, I won't bother about the details or history. The most important thing are the dates which I managed to find the answers now.
Based on the 8.6 year cycle, with a 2.15 year interval (see diagram), this model predicts the future highs and lows in the stock market. From now, the future highs and lows are:
2009.3 = April 23, 2009 (High)
2011.45 = June 18, 2011 ( Low)
2013.6 = Dec 8, 2013 (High)
2015.75 = July 10, 2015 (High)
2017.9 = Jan 12, 2017 (High)
Take note of April 23, 2009! But the high might be earlier than predicted.
