I predict that within the next five years the Cubs will win the world series.
I too look at those projected returns for the future as I stategize for the future but the man behind the mirror keeps whispering to me that anyone who says he can predict the future is but one thing. A lyer.
While the market could double or more in the next five years the odds are not likely at these valuations. Still Mr Market has made many learned prognosticators look foolish in the past.
Many many excellent folks in finance are predicting lower returns for the future and I pay attention but nonetheless they still could be wrong.
I do feel, however, that I likely am preaching to the choir here.
