Ans. CONCEPT OF RISK
Risk
may be understood as the possibility of adverse happening. We consider those
situations as risky, if they involve larger deviations from the expectations.
Whether a particular situation involves risk or not depends on with what
precision we can estimate the possibility of occurrence of a particular event.
This gives raise to the following three states of possibilities:
A.
Certainty
B.
Uncertainty
C.
Risk
Certainty
is a situation reflecting the happening of a particular event as expected with
zero deviation. In case of certain ‘All Truths’, there will be no deviation.
Like the sun rising in the east and inevitability of death. Similarly, there
may be some business situations involving near certainty. Expecting to sell a
certain number of bags of rice in a locality, when you are a monopolistic and
rice is the staple food of the people of the locality.
Uncertainty
is a situation that makes prediction difficult. One may not be sure of the
occurrence of a particular event with any degree of precision. People find it
often difficult to make predictions pertaining to weather. So also, the
meteorological department , sometimes. To attempt to define uncertainty with
any rigor presents extremely complex and
hazardous conceptual and mathematical problems. In practice also, it is
difficult to deal with the situations of uncertainty, since nothing stands to
prediction.
Continuum Reflecting the possibility
of occurrence of an Event
Certainty (100%) Risk Uncertainty
(0%)
The
third state of possibility, i.e., risk, is said to be a situation lying in
between the above two states, viz., certainty and uncertainty. This can be best
understood in the form of a continuum with certainty and uncertainty on the two
ends and risk covering the middle ground.
In
statistical terminology, Risk is referred to be a situation in which future
outcomes, together with their associated probabilities are known. In other
words, it is said to be as dispersion in a subjective probability distribution.
As
a matter of fact, a businessman can face confidently, the situation of risk
only. There will be no difficulty in making decisions under the situation of
certainty; and he will not be precise with any amount of sophistication of
tools under uncertainty. Therefore, what can a manager reasonably perform are
the situations of risk only. The theory of finance, therefore, realizes the
significance of risk in final decision-making.
Ex-ante
and Ex-Post Risk : Risk, as a
concept, has both ex-ante and ex-post meaning. Ex-ante risk refers to a
decision variable reflecting the probability of realizing unfavourable outcomes
in the future as a result of a decision made currently. Ex post risk refers to
observed variation in outcomes during prior periods. This risk is historical.
The estimation and evaluation of future outcomes, based on current information,
is the most difficult exercise involved in financial decision making. Finance
literature considers the ex ante concept of risk as having greater value than
the ex-post concept of risk, since it is the former that a finance manager
confronts.
