A) The CML is the line from the risk-free rate through the market portfolio. B) The CML is the best atta

10、inable capital allocation line. C) The CML is also called the security market line. D) The CML always has a positive slope. E) The risk measure for the CML is standard deviation. Answer: C Difficulty: Moderate Rationale: Both the Capital Market Line and the Security Market Line depict risk/return re

11、lationships. However, the risk measure for the CML is standard deviation and the risk measure for the SML is beta (thus C is not true; the other statements are true). 8. The market risk, beta, of a security is equal to A) the covariance between the securitys return and the market return divided by t

12、he variance of the markets returns. B) the covariance between the security and market returns divided by the standard deviation of the markets returns.
