Risk and Volatility
When most people think of risk in their investment
portfolios, they think of price fluctuations in the open
market (also known as volatility or market risk). However,
many investors don't realize that even "safe" investments
can be affected by the risk of inflation eroding purchasing
power. With that in mind, you should be aware of the other
types of risk you may encounter with different investments.
-
Inflationary risk, also known as purchasing power risk, is the decline
in the purchasing power of dollars over time, so that
even the "safest" investments can leave investors with
substantially less purchasing power. For example,
assuming an inflation rate of 4% for the next 10 years,
if you have a $100 today, 10 years from now inflation
will have eroded that $100 so that it is worth only
$68.
-
Investment or credit risk
is the possibility that a company backing a security
will not be sufficiently profitable to remain in
business.
-
Interest rate risk
is the fluctuation in the prices of some investments,
such as bonds, due to changes in prevailing interest
rates. When interest rates rise, new issues of bonds
come to market with higher yields than older
securities, making those older bonds worth less. Hence,
their prices go down. When interest rates decline, new
bond issues come to market with lower yields than older
securities, making those older, higher-yielding bonds
worth more. Hence, their prices go up. As a result, if
you have to sell your bond before maturity, it may be
worth more or less than you paid for it.
When considering your own risk tolerance, you should
understand that investments associated with higher risk
typically offer higher reward potential over time. A key
factor to successful investing is to identify how much risk you are willing to assume in exchange for potential investment gains.
