What’s the best asset allocation for your age?

Conventional wisdom suggests the percentage of equities in a portfolio should equal 100 minus your age—so 40% stocks if you’re 60 years old. But in our low-rate environment, coupled with the fact people are living longer, this outdated equation may not provide the returns needed for a comfortable retirement.

A more aggressive guideline is to subtract your age from 120 for more stock growth that should make your money last longer—so 60% stocks if you’re 60 years old. Conservative investors can use 110.
