8.4 Risk and return: The Capital Asset Pricing Model (CAPM)
1) The difference between the return on the market portfolio of assets and the risk-free rate of return
represents the premium the investor must receive for taking the average amount of risk associated with
holding the market portfolio of assets.
2) Total risk is the sum of a security's nondiversifiable and diversifiable risk.
3) Total risk is attributable to firm-specific events, such as strikes, lawsuits, regulatory actions, or the loss
of a key account.
4) As any investor can create a portfolio of assets that will eliminate all, or virtually all, nondiversifiable
risk, the only relevant risk is diversifiable risk.
5) Diversifiable risk is the relevant portion of risk attributable to market factors that affect all firms.
6) Diversified investors should be concerned solely with nondiversifiable risk because they can easily
create a portfolio of assets that will eliminate all, or virtually all, diversifiable risk.
7) Nondiversifiable risk reflects the contribution of an asset to the risk, or standard deviation, of the
portfolio.
8) Systematic risk is that portion of an asset's risk that is attributable to firm-specific, random causes.
9) Unsystematic risk can be eliminated through diversification.
10) Unsystematic risk is the relevant portion of an asset's risk attributable to market factors that affect all
firms.
11) The required return on an asset is an increasing function of its nondiversifiable risk.
12) The empirical measurement of beta can be approached by using least-squares regression analysis to
find the regression coefficient (bj) in the equation for the slope of the "characteristic line."
13) Investors should recognize that betas are calculated using historical data and that past performance
relative to the market average may not accurately predict future performance.
14) The beta coefficient is an index that measures the degree of movement of an asset's return in response
to a change in the market return.
15) The beta coefficient is an index of the degree of movement of an asset's return in response to a change
in the risk-free asset.
16) Systematic risk is also referred to as ________.
A) business specific risk
B) internal risk
C) nondiversifiable risk
D) maturity risk
