Unformatted text preview: : [RxCML] = rf + x(E[RMkt] - rf) E .14 = .05 + x(.12 - .05) x = .09 / .07 = 1.286 So the portfolio is long 129% market and short 29% risk-free asset SD(RxCML)= xSD(RMkt) 1.286(.16) = .2057 = 20.6% 26) Which of the following statements is false? A) The risk premium of a security is equal to the market risk premium (the amount by which the marketʹs expected return exceeds the risk-free rate), divided by the amount of market risk present in the securityʹs returns measured by its beta with the market. B) We refer to the beta of a security with the market portfolio simply as the securities beta. C) There is a linear relationship between a stockʹs beta and its expected return. D) A security with a negative beta has a negative correlation with the market, which means that this security tend to perform will when the rest of the market is doing poorly. Answer: A Explanation: A) The risk premium of a security is equal to the market risk premium (the amount by which the market’s expected return exceeds the risk-free rate), multiplied by the amount of market risk present in the security’s returns measured by its beta with the market.

Monsters Inc. has a 24% volatility and a correlation with the market of .60, while California Gold Mining has a 32% volatility and a correlation with the market of -.7. Assume the CAPM assumptions hold. 27) Monstersʹ required return is closest to: A) 10.0% B) 13.0% C) 11.5% D) 15.5% Answer: C Explanation: A) B) C) (.24)(.6) SD ( RMonsters )Corr ( RMonsters, Rmkt ) = = .80 bMonsters = .18 SD( Rmkt ) ri = rf + b(E[RMkt] - rf) = .05 + .8(.13 - .05) =.114 D) 12.4 Determing Beta 28) Which of the following stateme...
