• A: 5.00%
• B: 6.80%
• C: 7.25%
• D: 7.50%

6. A portfolio’s risk depends on:

7. Which of the following statements is correct?

• A: Systematic risk can be eliminated via portfolio diversification.
• B: Market portfolio is an equally-weighted portfolio of all risky assets.
• C: There are no portfolios above the efficient frontier.
• D: Portfolio risk depends only on the variances of assets in the portfolio.

## Section C: CAPM and APT

8. What is the expected return on a stock if it has a beta of 0.4, the risk-free rate of return is 2%, and the market return is 5%?

• A: 4%
• B: 2%
• C: 5.6%
• D: 3.2%

9. Which of the following statements is incorrect?

• A: Arbitrage pricing theory accommodates multiple systematic risk factors.
• B: CAPM posits a linear relationship between an asset’s expected return and its beta.
• C: The slope of the security market line is equal to the beta.
• D: Factor betas capture an asset’s sensitivity to systematic risk factors.

10: Which of the following is not one of the factors of the Fama French 3-factor model?

• A: Market risk
• B: Momentum
• C: Size
• D: Value

End of the investments quiz.

#### Solutions

1: C. (\$11 + \$2 − \$10) / \$10 = 30%. Read more about net returns versus gross returns.

2: A. [(1 − 20%) * (1 + 30%) * (1 + 5%)]1/3 − 1 = 2.98%. See our post geometric average return calculations.

3: D. First, calculate the average return: (8% + 12%) / 2 = 10%. Then, the realized volatility is [ (8% − 10%)2 + (12% − 10%)2 ]1/2 = 2.83%. Check the lesson on return volatility for detailed explanations.

4: A. 60% * 12% + 40% * ( −3%) = 6%. Read more about expected return calculations.

5: B. ( €4,000 / €5,000 ) * 8% + ( €1,000 / €5,000 ) * 2% = 6.8%. You can find a more detailed explanation here: Portfolio return calculation.

6: D. Read our post on portfolio risk to learn more.

7: C. There are individual assets and portfolios below the efficient frontier but not above it. A is incorrect – it is the idiosyncratic risk that can be eliminated via diversification. B is incorrect since the market portfolio is a value-weighted portfolio. D is incorrect because portfolio risk depends on covariances as well as variances.

8: D. 2% + 0.4 * (5% − 2%) = 3.2%. Go to our post on the capital asset pricing model for details.

9: C. In fact, the slope of the security market line is equal to the market risk premium.

10: B. Fama-French 3-factor model contains market risk, size factor, and value factor. Factor models are covered in our post on the arbitrage pricing theory.
