Risk
tolerance, a person's attitude towards accepting risk, is
an important concept that has implications for both financial
service providers and consumers. For the latter, risk tolerance
is one factor which may determine the appropriate composition
of assets in a portfolio, which is optimal in terms of risk
and return relative to the needs of the individual. Risk is
often defined as portfolio volatility, or the fluctuation
in the value of assets over time. At a personal level, risk
can mean the chance that one will not achieve one's goals
or the risk of losing one's savings. Understanding tolerance
for risk, which differs for each investor, is a key to choosing
an investment program. The tolerance for risk is a very personal
characteristic that may be difficult to determine and may
change over time.
Despite
its importance in the financial services industry, there remain
some unresolved questions with respect to the `determinants'
of risk tolerance. Although a number of factors have been
proposed and tested, a brief survey of the results reveal
a distinct lack of consensus. First, it is generally thought
that risk tolerance decreases with age (Wallach and Kogan,
1961; Mclnish, 1982; Morin and Suarez, 1983; and Palsson,
1996), although this relationship may not necessarily be linear
(Riley and Chow, 1992; and Bajtelsmit and VanDerhai, 1997).
Investment managers use this input (age) as a measure of the
time remaining until a client's financial assets are needed
to meet goals and objectives. In addition to being used as
a proxy for time, investment managers also use age as a measure
of someone's ability to recoup financial losses. Income and
wealth are two related factors that are hypothesized to exert
a positive relationship on the preferred level of risk (Lee
and Hanna, 1991; Riley and Chow, 1992; and Schooley and Worden,
1996). |
