Considering the tremendous amounts of
volatility stock investors have had to deal with
over the last decade and the returns from holding a mix of bonds and stocks that investors should expect to earn
over the next decade, Mr. Bernstein, who
passed away in 2009, would surely be making the same argument.
Typically they'll do about 100
passes over the plan to get a sense of its probable risk versus growth - potential versus
volatility, and tweak the plan until the normal
volatility is within the range you've said you're comfortable with while trying to produce the best return with the least risk.
