According to the capital asset pricing model (i.e., equation 10.11):
kE = RF + (RM – RF) × βOnogo
6. Practical application of the capital asset pricing model.
This question is about some of the practical problems encountered in applying the capital asset
pricing model (CAPM). Of the variables in the model, RF (the risk-free rate) is directly
observable and (the firm’s equity beta) can be fairly easily measured by regressing the returns
of a particular security, or securities belonging to the same industrial sector, on the returns of a
market index. It is the expected average return on the market, RM, which creates the measurement
Why have some investment banks been using very low market risk premiums? Since the lower
the market risk premium, the lower the cost of capital that is used to discount expected future
cash flows, company valuations will be higher. A cynic might suspect the banks have a strong
incentive to obtain high valuations since their fees will be larger. Sellers of a company in a
