What will be the average rate of return of Asian CERC Ltd.'s shares for past 6 years.
All possible questions which the investor may ask, the most important one is concerned with
the probability of actual yield being less than zero, that is, with the probability of loss. This is
the essence of risk. A useful measure of risk should somehow take into account both the
probability of various possible "bad" outcomes and their associated magnitudes. Instead of
measuring the probability of a number of different possible outcomes, the measure of risk
should somehow estimate the extent to which the actual outcome is likely to diverge from the
expected.
Two measures are used for this purpose: The average (or mean) absolute deviation and the
standard deviation.
