Rate of return
The annual rate of return for this investment or savings
account. The actual rate of return is largely dependant
on the type of investments you select. From January 1970
to December 2007, the average compounded rate of return
for the S&P 500, including reinvestment of dividends, was
approximately 11.4% per year (source: www.standardandpoors.com).
During this period, the highest 12-month return was 61%,
and the lowest was -39%. Savings accounts at a bank can
pay as little as 1% or less.
It is important to remember that future rates of return
can't be predicted with certainty and that investments
that pay higher rates of return are generally subject
to higher risk and volatility. The actual rate of return
on investments can vary widely over time, especially for
long-term investments. This includes the potential loss
of principal on your investment. It is not possible to
invest directly in an index and the compounded rate of
return noted above does not reflect sales charges and
