Ch. 11 Risk and Return
What is the expected return of a security with a beta of 1.2 if the risk-free rate is 4 percent and the expected return on the market is 12 percent?
4% + 1.2(12% - 4%) = 13.6%
What is the expected return for a security if the risk-free rate is 5%, the expected return on the market is 9%, and the security's beta is 1.5?
Expected return for a security= 5 + 1.5 x (9 - 5) = 11%
What is the equation for the capital asset pricing model?
Expected return on security = Risk-free rate + Beta × (Return on market - Risk-free rate)
True or false: The expected return of a portfolio is a combination of the weights of each asset in a portfolio.
False; The expected return on a portfolio is a combination of the expected returns on the assets in the portfolio.
True or false: Portfolio weights can be defined as the dollars invested in each asset.
False; percentages

What is systematic risk?
It is a risk that pertains to a large number of assets.
Which of the following types of risk is not reduced by diversification?
Systematic, or market risk; Systematic risk cannot be diversified away.
What is the slope of the security market line (SML)?

cost of capital
The minimum required return on a new project is known as the:
cost of capital
The security market line (SML) shows that the relationship between a security's expected return and its beta is ______.
positive; the higher the risk, the higher the expected return.
Even if the portfolio is well diversified, the investor is still exposed to _____ risk.
systematic
A portfolio can be described by its portfolio weights which are defined as _____________________.
the percentage of dollars invested in each asset
The systematic risk principle argues that the market does not reward risks:
- that are diversifiable - that are borne unnecessarily
What is the beta of the risk-free asset?
0
By definition, what is the beta of the average asset equal to?
1
True or false: A well-diversified portfolio will eliminate all risks.
False; Even if the portfolio is well diversified, the investor is still exposed to systematic risk
True or false: Expected return and inflation are the two components of risky return in the total return equation.
False; Market risk and unsystematic risk are the two components of risky return in the total return equation.
True or false: The calculation of the portfolio beta is similar to the calculation of the portfolio weights.
False; The calculation of the portfolio beta is similar to the calculation of the expected return.
What is the intercept of the security market line (SML)?
The risk-free rate
According to the capital asset pricing model (CAPM), what is the expected return on a security with a beta of zero?
The risk-free rate of return; Risk-free rate + 0 × Market risk premium = Risk-free rate
True or false: According to the capital asset pricing model (CAPM), the risk-free rate of return is the expected return on a security with a beta of zero. True
True
True or false: The expected return is the return that an investor expects to earn on a risky asset in the future.
True
True or false: It is possible for the unsystematic risk of a portfolio to be reduced almost to zero.
True; If enough securities are added, all the unsystematic risk of the securities in the portfolio should cancel one another out.
The calculation of a portfolio beta is similar to the calculation of:

Which of the following statements is (are) true about variance?
- Standard deviation is the square root of variance. - Variance is a measure of the squared deviations of a security's return from its expected return.
The CAPM shows that the expected return for an asset depends on which three things?
- The amount of systematic risk - The reward for bearing systematic risk - The pure time value of money
What are the two components of risky return (U) in the total return equation?
- Unsystematic risk - Market risk U = m + Ɛ
What is the definition of expected return?
It is the return that an investor expects to earn on a risky asset in the future.
If an asset has a reward-to-risk ratio of 6.0%, that means it has a __________ of 6.0% per unit of _______.
risk premium; systematic risk

As more securities are added to a portfolio, what will happen to the portfolio's total unsystematic risk?
- It is likely to decrease. - It may eventually be almost totally eliminated.
The true risk of any investment comes from:
-surprises -unanticipated events
What is a portfolio?
a group of assets held by an investor, holding a single asset would generally not be considered to be a portfolio.
