5. Portfolio beta and weights Rafael 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 Atteric Inc. (AI) Investment Allocation 35% 20% Beta 0.600 1.500 Standard Deviation 23.00% 27.00% Arthur Trust Inc(AT) Lobster Supply Corp. (LSC) Baque Co.
