DJIA Possible Macro Picture 1917-1929 vs 2000-2016

Possible scenario if the current secular bear market carries on rallying from here...
Comparison of the current market vs. Quarterly chart from 1917-1929

Could rally up to 20,000 hit some major resistance, then correct lower into a wave 4, and eventually go up to 23,000 then fall 75-83% causing the next depression for the next 10-15 years afterwards

Possibly the worst case scenario and a big "what if...." using fib projections to estimate the potential turning points

Refer my 100 year to see the historical secular bear markets,
1917-1942 = 25 years, Secular bear market/ depression
1942-1966 = 24years, Bull market Industrial age
1966-1983 = 17 years, Secular bear market
1983-2000 = 17 years, Bull market Information age
2000-2016 = 16 years to date Secular bear market large corrective pattern
