Longer timeframe charts from 2005 suggest that Wave 1 ended at April 206 at 295 and then a long multi year Wave 2 correction and then 3rd wave from March 2010 till 2015.
Wave 4 correction for past 2 months and may have ended at 782. Price is just about 10% higher than Wave 4 lows.
Potential 5th wave to reward a minimum of 25% in next 1 to 2 years.
Suggest to buy with SL = Monthly close below 760.
