CAPM depends upon the
following things:
- Risk Free Rate on Risk Free
Assets
- Expected Market return on
stock
- Beta which is the correlation of
stock return with market returns.
Importance of the components
of CAPM:
- Risk Free Rate :
This rate compensates the investors for placing money in any
investment over a period of time. These rates are generally of
T-bills issued by government, which is assumed to be the risk-free
and is not affected by market fluctuations.
- Expected market return on
stock : The rate is the return of stock in market over a
period. This is imortant as it tells how much return is expected
when investment is done in stocks.
- Beta: Beta is the
risk- measure the volatlity of the stock and the market as well as
the correlation between the stock and the market. It is important
as investors will be interested in knowing how much risky is the
stock to the market, so as they do not experience huge losses, and
if they are ready to take the risk of an risky stock, they must be
compensated with higher returns.
