Let annual growth be x%, and number of years being y.  Usually the stock doubles when x times y = 72. 

For example:

annual growth is 8%, it will take 9 years to double.  1.08 ^ 9 ~ 2. 

annual growth is 5%, it will take 14 years to double.  1.05 ^ 14 ~ 2.

So if you want to double in 6 years, the annual growth has to be 12%.   This is not the historical performance of SP 500. 

So where is your 历史经验 coming from？
