4. Portfolio beta and weights Gregory is an analyst at a wealth management firm. One of his clients holds a $5,000 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: . Beta Standard Deviation Stock Atteric Inc. (AI) Arthur Trust Inc. (AT) Lobster Supply Corp. (LSC) Baque Co. (BC) Investment Allocation 35% 20% 0.600 38.00% 42.00% 1.600 15% 30% 1.200 0.300 45.00% 49.00% Gregory calculated the portfolio's beta as 0.800 and the portfolio's required return as 8.4000% Gregory thinks it will be a good idea to reallocate the funds in his client's portfolio.
