Well, I agree that this all is just guess work. But, here is my take.
We had our first secular bull market from 1979 to 1992. During this time period sensex rose from 100 in 1979 to 4500 in 1992. (45 times in 13 years, that too for Index!!)
After this 13 years of secular bull market, we expereince secular bear market from 1992 to 2003. During this 11 years of bear market, sensex went from 4500 to 3000 at bottom in April 2003.
From 2003 onwards, we are on to next secular bull market. If you ask Eliot wave theories, this second bull market will be stronger and longer than first bull market.
If so, this bull market will last much more than 13 years which would take us the time frame of 2016 to 2019 for the peak of this secular bull market.
Also, if this bull market is stronger than last one, return should be more that 45 times which wa achieved last time. Take a number of 70 times and with starting point of 3000, it gives us sensex number of 2,10,000 (Two lacs ten thousand)
Well, as I said, all this is guess work only. Hence, please do not feel offended.
