Hi Friends! We at WWW.assignmentconsulatncy

help.
It has been long time since I came out with a blog. Today, I am
going to concentrate on Risk premium. The CAPM model which is basically used to
quantify the market risk in the form of market return consists of two things
which is given by
Ke = Risk free rate +
Risk premium
= Rf + ( Rm – Rf )
The second value
basically speaks about the premium that an investor expects from his investment
for taking extra risk to invest in the stock of a particular company. The most
simple step to calculate risk premium is to subtract ( Rf) from expected market
return ( Rm ). But the problem with this approach is that we use historical
data to calculate the average value of Rm. Hence, the value changes
significantly with change in sample size and the method use to find average.
Secondly, the standard error also increases with increase in the standard
deviation of the return as standard error is given by
S.D/ Sqrt(n)
Where n= Sample size
For example, If we
calculate Rm from past 20 years data of BSE with an assumption that standard
deviation is 20 %, then the value of standard error will be around 4.4 %, which
is significantly large. Hence we must explore some other methods to calculate
Risk premium.
Equity risk premium can
also be calculated by using country risk premium. Generally, Country equity
risk premium shows the value that an investor expects to get because of the
extra risks that he takes compare to stable equity market. For ex, the U.S.A
market is considered extremely stable. Hence, CERP for U.S.A is must be kept
minimum or zero.
Country risk premium can
be calculated in one of the two ways
1)
By treating the value of CERP equal to the value of default spread i.e. the
extra return that an investor expects from the risk associated with country
bond as compare to stable market bond as per the rating given by rating
agencies But the problem with this approach is that the risk taken by equity’s
investors is more than bond’s investors. Hence, CERP should be more than
default spread.
2)
In order to overcome above problem we can adjust the above calculated CERP by
multiplying it with ratio of standard deviation of country’s equity market and
the country’s bond market.
Adjusted CERP = Default
spread * ( S.D of equity market/ S.D of Bond market)
We generally use second
method to calculate CERP. Hence, here onwards we use CERP in place of adjusted
CERP in all the discussions. Once we calculated the CERP, the risk
premium associated with one’s equity can be calculated in one of the following
two ways:-
1)
If we assume that the risk taken by company in other country is similar to
home’s country, then Risk premium is given by
Risk premium =
Beta*(CERP+ US premium)
2)
If we assume that the risk is different in different countries then,
Risk premium = Beta*(US
premium) + lambda *(CERP)
Here, lambda shows the
ratio of revenue earned by company in domestic market to the average revenue
earned by similar’s business firm in the same market. In the above example we
used US premium while calculating risk premium because we assume that the US is
the most stable country and there is negligible or no risk associated with US
market.
Hence, once the risk
premium is calculated, add it to risk free rates to get cost of equity (Ke).
Hoping, this article will help you in understanding the concept behind
calculation of (Ke) by using different approaches. Kindly follow my blogs to
