4. Portfolio beta and weights Brandon is an analyst at a wealth management firm. One of his clients holds a $10,000 portfolio that consists of four stocks. The investment allocation in the portfolio along with the contribution of risk from each stock is given in the following table: Stock Investment Allocation Standard Deviation 35% 53.00% Atteric Inc. (AI) Arthur Trust Inc. (AT) Lobster Supply Corp. (LSC) Baque Co. (BC) 20% 15% 30% Beta 0.600 1.500 1.200 0.500 57.00% 60.00% 64.00% Brandon calculated the portfolio's beta as 0.840 and the portfolio's required return as 8.6200%. Brandon thinks it will be a good idea to reallocate the funds in his client's portfolio. He recommends replacing Atteric Inc.'s shares with the same amount in additional shares of Baque Co. The risk-free rate is 4%, and the market risk premium is 5.50%. According to Brandon's recommendation, assuming that the market is in equilibrium, how much will the portfolio's required return change? (Note: Do not round your intermediate calculations.) O 0.1502 percentage points 0.2214 percentage points 0.2387 percentage points 0.1925 percentage points Analysts' estimates on expected returns from equity investments are based on several factors. These estimations also often include subjective and judgmental factors, because different analysts interpret data in different ways. Suppose, based on the earnings consensus of stock analysts, Brandon expects a return of 9.93% from the portfolio with the new weights. Does he think that the required return as compared to expected returns is undervalued, overvalued, or fairly valued? Fairly valued Undervalued Overvalued Suppose instead of replacing Atteric Inc.'s stock with Baque Co.'s stock, Brandon considers replacing Atteric Inc.'s stock with the equal dollar allocation to shares of Company X's stock that has a higher beta than Atteric Inc. If everything else remains constant, the portfolio's risk would
