Of course, there's a bit more to it today.
In today's terms, asset allocation is the process of
selecting asset classes, such as stocks and bonds, and
determining their proportions within an investment
portfolio. But that's a basic explanation of what might be
one of the most important decisions an investor makes.
Research shows that it's the asset allocation decision
that accounts for nearly 92% of the variation between
returns on different investment portfolios.
Here's the theory: Individual asset classes have distinct
characteristics and historically don't react in tandem
under the same market conditions. When some are
falling in value, others may be rising.
By strategically diversifying your assets, you help offset
declines in any one particular class and smooth out
the ups and downs of your portfolio.
When it comes to shaping an appropriate asset allocation
strategy, information is power. That's because it should
be built around you.
