11. Portfolio beta and weights Rafael is an analyst at a wealth management firm. One of his clients holds a $7,500 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 Beta Standard Deviation 23.00% 35% 0.600 20% 1.500 27.00% Atteric Inc. (AI) Arthur Trust Inc. (AT) Lobster Supply Corp. (LSC) Transfer Fuels Co. (TF) 15% 1.100 30.00% 30% 0.300 34.00% Rafael calculated the portfolio's beta as 0.7550 and the portfolio's expected return as 3.21%. Rafael 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 Transfer Fuels Co. The risk-free rate is 4%, and the market risk premium is 5.50%. According to Rafael's recommendation, assuming that the market is in equilibrium, how much will the portfolio's required return change? (Note: Round your intermediate calculations to two decimal places.) O 0.45 percentage points O 0.72 percentage points 0.58 percentage points 0.67 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, Rafael expects a return of 9.13% from the portfolio with the new weights. Does he think that the revised portfolio, based on the changes he recommended, is undervalued, overvalued, or fairly valued? Undervalued Overvalued Fairly valued Suppose instead of replacing Atteric Inc.'s stock with Transfer Fuels Co.'s stock, Rafael 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 beta would and the required return from the portfolio would
