Question 23

Review LaterAdd Note

You are given the following returns on "the market" and Stock F during the last three years.We could calculate beta using data for Years 1 and 2 and then, after Year 3, calculate a new beta for Years 2 and 3.How different are those two betas, i.e., what's the value of beta 2 ? beta 1? (Hint: You can find betas using the Rise-Over-Run method, or using your calculator's regression function.) $\begin{array} { c r r } \text { Year } & \text { Market } & \text { Stock F } \\1 & 6.10 \% & 6.50 \% \\2 & 12.90 \% & - 3.70 \% \\3 & 16.20 \% & 21.71 \%\end{array}$

A stock you are holding has a beta of 2.0 and the stock is currently in equilibrium.The required rate of return on the stock is 15% versus a required return on an average stock of 10%.Now the required return on an average stock increases by 30.0% (not percentage points) .The risk-free rate is unchanged.By what percentage (not percentage points) would the required return on your stock increase as a result of this event?

The slope of the SML is determined by the value of beta.

Your mother's well-diversified portfolio has an expected return of 12.0% and a beta of 1.20.She is in the process of buying 100 shares of Safety Corp.at $10 a share and adding it to her portfolio.Safety has an expected return of 15.0% and a beta of 2.00.The total value of your current portfolio is $9,000.What will the expected return and beta on the portfolio be after the purchase of the Safety stock? $\quad\underline{\text {Ip}}\quad\quad\underline{\text {bp}}$ a. $11.69 \% ; 1.22$ b. $12.30 \% ; 1.28$ c. $12.92 \% ; 1.34$ d. $13.56 \% ; 1.41$ e. $14.24 \% ; 1.48$

Which of the following is NOT a potential problem with beta and its estimation?

Calculate the required rate of return for the Wagner Assets Management Group, which holds 4 stocks.The market's required rate of return is 15.0%, the risk-free rate is 7.0%, and the Fund's assets are as follows: $\begin{array} { c r r } \text { Stock } & \text { Investment } & \text { Beta } \\\text { A } & \$ 200,000 & 1.50 \\\text { B } & 300,000 & - 0.50 \\\text { C } & 500,000 & 1.25 \\\text { D } & 1,000,000 & 0.75\end{array}$

Which of the following statements is CORRECT?

For markets to be in equilibrium (that is, for there to be no strong pressure for prices to depart from their current levels) ,

We will almost always find that the beta of a diversified portfolio is less stable over time than the beta of a single security.
